Cars

Car

A car (also called an automobile) is a machine used for travel (a vehicle). Cars are different from motorcycles, and bicycles because they have four wheels.

Structure
A car has an engine to move it, put together with three or more wheels (almost always four), a purpose-built body frame, and controls such as a steering wheel and brakes. They usually have a seat for the driver and at least one other seat for a passenger, and most have a total of 4 to 6.
Some small "city" cars carry only two people, and/or have very little luggage space; other types are able to carry many passengers or heavy loads. For example, family station wagons carry from 6 to 9 people, or fewer people with lots of luggage. A van or pickup truck is a car-like vehicle made for carrying medium sized loads, for example of goods for delivery or plumber's and builder's tools and materials.
In order for a car to work, it must have fuel, most often petrol, which is sometimes called gasoline, or diesel. Other less common fuels are natural gas, or electricity. Many car-making companies are also now trying to build vehicles that run successfully using hydrogen fuel cells, which are as convenient as petrol or diesel fuelled cars but do not give out any polluting exhaust gases (but making hydrogen may at first still need electricity made by a powerplant that burns similar fossil fuels).

History

The earliest automobiles recorded were actually steam engines attached to wagons. This was invented by Nicolas-Joseph Cugnot in the late 1700's. The steam engines were heavy and therefore the wagon was very slow and hard to control. Cugnot was the very first person to get into a motor vehicle accident when he crashed his wagon into a wall!
Also, there were in the 1830's that were powered by
electricity, but these were also very slow and heavy so they were eventually left behind.
The
internal combustion engine changed the way automobiles were to be powered. The engine used either gasoline, diesel, or kerosene to work. When the gas is exploded in a cylinder it pushes the piston down and turns the wheel.
Although many people tried to make a good car that would work well and sell well, people say that Karl Benz invented the modern automobile. He used a four-stroke type of internal combustion engine to power his "car". He began to sell his production vehicles in 1888.


Benz may have invented the first modern car, but Henry Ford is the man who sold the most cars to the most people. In 1910 he began making and selling his Model T, which was a huge success. Many people could afford this car, not just the rich. Ford mass produced his Model T, meaning he made a lot of them in a short time in a factory. People say that the Model T is the car that "put America on wheels". The Model T was the most popular car of the time because it was so cheap but it was still a good quality car that everyone could own.
Since then, many different kinds of cars have been designed and built, from minivans to sports cars.


Advantages
Cars are faster than walking or riding a bike if you are going a long way, can carry more than one person, and a large amount of luggage. Depending on local public transport quality, they can also be faster and far more convenient than using buses, trams or trains, and can often go where public transport cannot. 4-wheel drive "offroad" vehicles are particularly good at reaching places difficult for any other wheeled transport, allowing provision of goods, emergency services, transport of disabled or infirm passengers, and faster and safer journeys for able-bodied passengers over long distances and harsh terrain where this may otherwise have been impossible.
Another good thing is that if it's raining heavily it is better to use a car than a bicycle or motorcycle, or walking, because driving a car in these conditions can be less dangerous, and keeps passengers and possessions dry as most cars are enclosed (they have a roof, doors and windows). Modern cars are often safer in accidents in any conditions, as they have added safety features such as seat belts, airbags, crumple zones and side-impact protection that would be expensive or impossible on two-wheeled or light 3-wheeled vehicles, or most buses.



Disadvantages
Buying and running a car needs a lot of money, even more for a good quality one that is not too old. There are a lot of things to pay for - the car itself, fuel, parts (for example, tires/tyres), maintenance, repairs, insurance to cover the cost of crashes or theft, parking charges and road tolls and/or any tax or licensing fees charged by government.
If two cars crash they can hurt the people inside or around them. Traffic jams happen when there are too many cars trying to go the same way. They can cause pollution if too many are used in a small area like a city, and the combined pollution of the world's cars is thought to be partly to blame for climate change. Many places where lots of people live have public transportation (or mass transit) such as buses, trains, trams and subways. These can help many people get to different places very quickly, often faster and less expensive than by car when traffic jams are a problem. Some of these problems can be fixed, for example, by carpooling, which is putting many people who may not normally travel together in one car to share costs, use less fuel, and create less pollution and traffic.
If many cars try to travel around an older, or badly built town, that was not designed for cars, this can make these problems worse, and cause danger to other road users, for example people riding bicycles or walking. But, designing a town layout where everything is made for cars as the main transport can cause other problems. These include even more pollution and traffic, as everyone has to drive. Communities are divided up and separated with roads. People walking are in danger by expressways with too few foot bridges, small road bridges or other crossings. Designers now understand these problems and try to build more balanced systems.


Motorcycle

Motorcycle

A motorcycle (also called a motorbicycle, motorbike, bike, or cycle) is a single-track,[1] two-wheeled[2] motor vehicle. Motorcycles vary considerably depending on the task for which they are designed, such as long distance travel, navigating congested urban traffic, cruising, sport and racing, or off-road conditions.
Motorcycles are the most affordable form of motorised transport in many parts of the world, and for most of the world's population, they are also the most common type of motor vehicle.[3][4][5] There are around 200 million motorcycles (including mopeds, motor scooters and other powered two- and three-wheelers) in use worldwide,[6] or about 33 motorcycles per 1000 people. This compares to around 590 million cars, or about 91 per 1000 people. Most of the motorcycles, 58%, are in the developing countries of Asia,[7] while 33% of the cars (195 million) are concentrated in the US and Japan. In the two countries of India and China, there are a total of only 6 million cars, but 71 million motorcycles.[8][9] These numbers, worldwide, are dwarfed by the number of bicycles in use, estimated to be near twice the number of cars, or close to five times the number of motorcycles.[10]

Auto Rickshaw

Auto Rickshaw
Auto rickshaw or three-wheelers (tuk-tuk, auto, rick, autorick or rickshaw in popular parlance) is a motor vehicle and one of the chief modes of transport in many parts of South and East Asia, especially as a vehicle for hire. It is a motorized version of the traditional rickshaw or velotaxi, a small three-wheeled cart operated by a single individual, and is related to the cabin cycle.
Auto rickshaws are particularly popular where there is traffic congestion. They are common in many Asian countries such as Bangladesh, Cambodia, India, Laos, Pakistan, Sri Lanka and Thailand. As well as some African countries such as Ethiopia.
Design
An auto rickshaw is generally characterized by a sheet-metal body or open frame resting on three wheels, with handle bars like a motorcycle, a canvas roof with drop-down sides, a small cabin in the front of the vehicle for the driver (sometimes called an auto-wallah), and seating space for up to three passengers in the rear. They are generally fitted with an air-cooled scooter version of a two-stroke engine, with handlebar controls instead of a steering wheel. Auto rickshaws are light vehicles.



Hiring
Hiring an auto rickshaw often involves negotiating a fee with the driver .
In the major cities of India, such as Chennai, Ahmedabad, Thiruvananthapuram, Bengaluru and Delhi, drivers are required to install fare meters in their auto rickshaws. These meters are calibrated according to the city guidelines.
In cities such as Delhi, Mumbai, Kolkata, Chennai, Pune, Hyderabad and Bengaluru, traffic-regulating authorities have implemented a schedule of predetermined fares. For example, in Chennai in 2006, the predetermined fare within the central city was approximately Rs. 50.
Regional variations
As a mode of transport, the auto rickshaw is turning out to be a major employer in India. All major nationalized banks of India offer loans to buy one under self-employment schemes. Major auto rickshaw manufacturers in India include Bajaj Auto and Force Motors (previously Bajaj Tempo). A two-wheeler major, TVS Motors, has announced it will enter the auto rickshaw market with a technologically updated and a less polluting vehicle, in early 2006. Not restricted to cities, auto rickshaws are also prevalent in large numbers in Indian villages and in the countryside.
There is an initial charge at the beginning of a ride then the price normally increases in proportion to the distance. It is mandatory that the initial charge be set at a value given by the government. In Mumbai currently, the initial charge is 9 Rupees for up to 1 kilometre and thereafter proportional charges at a rate of Rs. 9 per kilometre. However one will find that in most cities this is usually disregarded by drivers and one must bargain for a price.



Known locally as Rickshah or autos, and used mainly by the lower-middle-class, auto rickshaws are a popular mode of transport for short routes within cities in Pakistan. One of the major brands of auto rickshaws is Vespa (an Italian Company). Environment Canada is implementing pilot projects in Lahore, Karachi and Quetta with engine technology developed in Mississauga, Ontario, Canada that uses compressed natural gas (CNG) instead of petrol in the two-stroke engines, in an effort to combat environmental pollution.[citation needed]
In many cities in Pakistan, there are also motor cycle rickshaws, usually called chand gari (moon car) or qingqi (after the Chinese company who first introduced this rickshaw to the market).
In addition to ferrying people around, an innovative use of auto rickshaws in public life was the demonstration in Peshawar in 2001 against the American invasion of Afghanistan.

Auto rickshaws commonly known as 'three-wheelers' can be found on all roads in Sri Lanka from the curvy roads through the hill country to the congested roads of Colombo transporting locals, foreigners, or freight about. Sri Lankan tuk-tuks are of the style of the light Phnom Penh type. Most tuk-tuks in Sri Lanka are a slightly modified Indian Bajaj model, imported from India though there are few manufactured locally and increasingly imports from other countries in the region and other brands of three wheelers such as Piaggio. In 2007 January the Sri Lankan government imposed an ban on all 2 stroke three wheelers and therefore the ones imported to the island now are only with a four stroke engine. Most three wheelers are available as hiring vehicles with few being used to haul goods and as private vehicles. Bajaj enjoys a virtual monopoly in the island with its agent being David Pieries Motor Co Ltd[1]. The hiring three wheelers in Sri Lanka never have distance meters and the charges are specified more or less on the whims of the driver.
Auto rickshaws are very popular & are common transport in Bangladesh. In Dhaka, they are called "CNGs" lovingly by the residents. These "CNGs" are painted green to signify that the vehicles are eco-friendly. In Khulna, they are called "Baby Taxi" or "Baby". Auto rickshaws are visible in other Bangladeshi cities including Chittagong, Rajshahi. Auto rickshaws are available in most of the towns and rural areas. In rural areas, they are known as "Tempo", "Nosimon" or "VotVoti".
Southeast Asia

Referred to as bajaj in Indonesia, are common throughout the country's capital Jakarta. Bajaj is India's main Auto-Rickshaw manufacturer.
The auto rickshaw, called tuk-tuk in Thailand, is a widely used form of urban transport in Bangkok and other Thai cities, as well as other major Southeast Asian and South Asian cities. It is particularly popular where traffic congestion is a major problem, such as in Bangkok and Nakhon Ratchasima.

In Cambodia, the term tuk-tuk is used to refer to a motorcycle with a cabin attached to the rear. Cambodian cities have a much lower volume of automobile traffic than Thai cities, and tuk-tuks are still the most common form of urban transport.
At the temple complex of Angkor, tuk-tuks provide a convenient form of transport around the complex for tourists. One can hire a tuk-tuk and driver by the day.
Siem Reap tuk-tuks are generally of the style of motorcycle and trailer. Phnom Penh tuk-tuks are by contrast one piece. They are the front end of a motorcycle comprising of steering, tank and engine/gearbox with a covered tray mounted at the back. The power is transferred by chain to an axle mounted to the modified rear fork which drives the two rear wheels. Suspended upon the rear fork is an open cabin with an in-line seat on each side. This arrangement can carry 6 people at ease, with their luggage in the leg space. It is not unusual to see these vehicles greatly overloaded, especially in outer suburbs and around markets.
Lao tuk-tuks are generally of the Phnom Penh style. They come as tuk-tuks or jumbo tuk-tuks. Jumbos have a larger 3 or 4 cylinder 4 stroke engine, many are powered by Daihatsu engines. While the smaller tuk-tuks carry similar loads to Cambodian tuk-tuks, and are geared similarly, jumbos' larger engine and cabin size allow for greater loads, up to 12 seated people at a squeeze, and higher top speeds. Jumbos are almost without exception only found in Vientiane. A few Thai tuk-tuks, which have fully enclosed cabins, have also made their way to Vientiane.

There are comparatively few Vietnamese tuk-tuks on the road. Most are in the two largest cities, Ho Chi Minh City or Hanoi as well as a few in other major tourist centres. Ho Chi Minh tuk-tuks generally comprise the motorcycle and trailer style of Siem Reap while Hanoi and Hoi An tuk-tuks are of the style of the light Phnom Penh type.
Auto rickshaws are an especially popular form of public transportation in the Philippines, where they are referred to as tricycles (Filipino: traysikel; Cebuano: traysikol).[1] As opposed to other types of auto rickshaws, tricycles are motorcycles fitted with a two-seater implement at the side to allow transportation. They usually carry 5 passengers, rarely more, although one can opt for a 'special' ride, albeit with an increase in price.
Central and South America
The mototaxi or moto is the Central American and Peruvian incarnation of the auto rickshaw. These are most commonly made from the front end and engine of a motorcycle attached to a two-wheeled passenger area in back. Commercially produced models, such as the Indian Bajaj brand, are also employed. In Guatemala the commercial vehicles are referred to as tuk-tuks.
Tuk-tuks operate, both as taxis and private vehicles, in Guatemala City, Guatemala, around the island town of Flores, Peten, in the mountain city of Antigua Guatemala, and in many small towns in the mountains. In 2005 the tuk-tuks prevalent in the Lago de Atitlán towns of Panajachel and Santiago Atitlán all appeared to be from India (Bajaj Auto).
Three-wheeled Coco taxis, resembling a coconut, are used in Havana, Cuba.

Africa
There are tuk-tuks in several Kenyan towns. Using them is somewhat cheaper than ordinary taxis. However, tuk-tuks cannot operate in mountainous towns, which are common in Kenya. Fierce competition with Boda-bodas (bicycle taxis) and Matatus (minibuses) hinders popularity of Tuk-tuks, especially within the interior of Kenya. While they may not be as commonly found in Kenya, one does come across quite a number of them in the coastal regions, which are less mountainous. For example, in the town of Malindi they offer a less expensive and easy mode of transportation. Tuk-tuks are also common in Ethiopia, and is becoming common in Tanzania, particularly in the outer areas of Dar es Salaam, as well as, from 2009, in Maputo, Mozambique. In Tanzania and Ethiopia they are known as Bajajis, called after the Bajaj Auto company which manufactures many of them.
Other Countries
United Kingdom
The first Tuk Tuks to enter service in the United Kingdom were supplied and built by MMW Imports under the brand name MMW Tuk Tuks, The very first Private Hire license was issued to an MMW Tuk Tuk for tours of Bath in the '90s. MMW also gained full Hackney license in Weston Super Mare. MMW also now export Tuk Tuks from Thailand to New Zealand and Australia.
Tukshop of Southampton started the commercial importing of Bajaj rickshaws in 2003. Tukshop failed to gain an operator license for London after a number of media appearances in 2004.
A Bajaj tuk tuk is currently operated by Bangwallop of Salcombe, South Devon. Taking just two passengers at a time, the tuk tuk has an operator's license issued by VOSA and trips can be booked in advance.
Auto rickshaws were introduced to the city of Brighton & Hove on 10 July 2006 by entrepreneur Dominic Ponniah's company Tuctuc Ltd, who had the idea after seeing the vehicles used in India and Sri Lanka. They were CNG-powered, using a four-speed (plus reverse) 175 cc engine. Under the terms of their license, the Bajas ran on a fixed single route, and stopped only at designated stops. They are of the same design as traditional auto rickshaws in other countries.
An investigation was launched into Tuctuc Ltd's operation of the service after complaints were raised that routes, stopping points and timetables were not being adhered, primarily by the city's taxi drivers.[2] In November 2006, the company was fined £16,500 - the maximum penalty possible - by the South East Traffic Commissioner. After amendments were made to the timetable to reduce delays and improve reliability, the Commissioner allowed the company to keep its operating licence.[3] However, the company announced in January 2008 that it was ceasing operations, citing "archaic legislation" as the reason.[4]

Netherlands
Since 2007, tuk-tuks have been active in The Netherlands, starting with Amsterdam. They now operate in Amsterdam, The Hague, Zandvoort, Bergen op Zoom, the popular beach resort Renesse and Rotterdam. All of the tuk-tuks in The Netherlands are imported from Thailand. They are fitted with CNG engines and have passed the EURO-4 rules.

Fuel efficiency and pollution

In July 1998, the Supreme Court of India ordered the Delhi government to implement CNG or LPG (Autogas) fuel for all autos and for the entire bus fleet in and around the city. Delhi's air quality has improved with the switch to CNG, important in a city where people commonly wear masks for protection against smog. Initially, auto rickshaw drivers in Delhi had to wait in long queues for CNG cylinders refilling, but the situation has improved with the rise of stations selling CNG. Certain other local governments are also pushing for four-stroke engines instead of the current two-stroke versions. Typical mileage for an Indian-made auto rickshaw is around 35 kilometres per litre of petrol (about 2.9 L per 100 km, or 82 miles per gallon). Pakistan has passed a similar law prohibiting auto rickshaws in certain areas. CNG Rickshaws have started to appear in huge numbers in many Pakistani cities.
In January 2007 the Sri Lankan government also banned two-stroke trishaws to reduce air pollution. In the Philippines[5] there are projects to convert carburated two-stroke engines to direct-injected via Envirofit technology. Research has shown LPG or CNG gas direct-injection to be retrofit-able to existing engines in similar fasion to the Envirofit system[6]. Direct injection is standard equipment on new machines in India[7][8].

Traffic issues

Auto rickshaws have a top-speed of around 50 km/h (about 31 mph) and a cruising speed of around 35 km/h (22 mph). Traffic authorities in big cities try to implement mechanisms to reduce the resulting traffic slowing; however, none of these have really proven effective.
The MMW Tuk Tuk has a top speed of around 70mph and with the introduction of the new turbo will have much improved 0-60 start times, to allow for the increased speeds these Tuk Tuks have anti-roll bars and are fitted with disc brakes all round. The owner of MMW Tuk Tuks, Mr Michael Williams has over the years made huge strides forward in Tuk Tuk design.
The triangular form of the auto also makes maneuvering easy, with the front single wheel negotiating the available gap, and the rear two wheels forcing a larger space.
Racing
Due to their relatively low top-speed, auto rickshaws have never lent themselves to conventional road or street racing. However, their modest speed, simple construction and impressive fuel economy has endeared them to the international amateur adventuring community, most notably with the Indian Autorickshaw Challenge and more recently the Rickshaw Run.

Portrayal in media

Auto rickshaws are often portrayed in Indian films (Auto Shankar, Basha, Aye Auto, Oram Po) as well as some Hollywood and foreign productions such as the James Bond film Octopussy , the Canada-India film Amal and the Indonesian movie Pembalasan Rambu. Auto rickshaws are also prominent in the fuel-poor London of 2027 A.D. depicted in Children of Men. A memorable tuk-tuk chase features in the Thai film Ong-Bak: Muay Thai Warrior, climaxing with many of them driving off the edge of an unfinished elevated expressway. James Bond (Pierce Brosnan) rides in a tuk-tuk in a Visa Card commercial.[9]
