BIKE and scooter major Bajaj Auto is all set to bring the two stroke engine bikes back to the Indian market. The legendary two strokes engine technology, which was launched in the early 1990s (Bajaj Chetak, Kawasaki Bajaj 100, ) have already been launched in three-wheelers as Gasoline Direct Injection (GDi), which is superior with increased mileage and substantially less emission. The company is likely to customise the GDi technology for its two-wheeler products in the next few months. Bajaj Auto has introduced direct injection technology (as the GDi name suggest) replacing the carburettor which delivers better fuel efficiency and higher power (torque) than the conventional two-stroke engines. It also meets the stringent emission norms with 50% lower carbon monoxide ((CO) and 25% lower hydrocarbons and nitrous oxides (HC+NOx) than the earlier two stroke engines, which were phased out by two wheeler companies because they failed to meet the required emission norms. A senior Bajaj Auto executive confirmed that the same engine is likely to be strapped on a two wheeler. “It is a big leap in the two stroke technology and we are working to get it on our bikes and other two wheelers. The Gasoline Direct injection (GDi) engine has substantially lower emissions than even alternate clean fuels like CNG and LPG. Additionally, it has lower operating costs than four stroke technology that currently dominates the bike market.” According to sources in the automobile industry, Bajaj is working to combine its proven DTSi technology with the GDi technology on bikes with smaller engines. The company wants to put the same technology in the volume generating 125 cc-150 cc segments as an alternative to the existing four stroke engines. Bajaj Auto is also in the process of developing two wheelers that will run on CNG fuel. The two stroke engine had been a success in the past due to its higher torque (power), faster pickup and better vehicle stability due to the smaller engine. Company officials said that in the GDi technology, the fuel is injected through a common rail fuel line directly into the engine’s combustion chamber where it is completely burnt unlike the conventional carburettor run two-stroke engine which leaves out unburnt fuel and results n higher emission. After successfully launching the GDi-run three wheeler, the company is working on different variations of the technology which can fit into smaller vehicles like bikes and scooters. Some prototypes of the new technology is expected to be unveiled at the upcoming Auto Expo in January
