Tuk-Tuks

Tuk-Tuk is the sound these make when they run.

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 observed a dramatic improvement in the quality of air with the switch to CNG, and this is important for a city where it is not uncommon to see pedestrians and drivers wearing nurse's masks for protection against the prevalent city smog. Initially, auto rickshaw drivers in Delhi had to wait in long queues to get their CNG cylinders re-filled, but the situation has improved drastically with the rise of filling stations that sell 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). Cambodian tuk-tuks are 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. We recently reported on the unfortunate demise of the Bajaj 3-wheeler from the American market due to slow sales. Happily, a new brand of funky 3-wheelers is set to make its debut in the U.S. by way of Thailand. T

Tuk Tuk North America (TTNA) reports that its vehicles are currently undergoing EPA and NHTSA testing for road-use approval, though its line of trikes is reportedly already for sale for off-road use. Available in a number of passenger, cargo and truck body styles, the Tuk Tuk comes equipped with either a 200cc or 650cc version of a newly-designed, liquid-cooled four-stroke powerplant. This replaces the original two-stroker from which the vehicle received its funny-sounding name. TTNA also reports that its vehicles are available with both automatic and manual transmissions. Interestingly, the options page of the TTNA site shows an LPG kit which would convert the engine to run on dual fuels -- both liquefied petroleum and gasoline. http://www.tuktuknorthamerica.com/ Some of the models available have a Mitsubishi 650cc, water cooled gasoline engine that gets mid 50 mpg.
