The benefits of direct injection are even more pronounced in two-stroke engines, because it eliminates much of the pollution they cause. In conventional two-strokes, the exhaust and intake ports are both open at the same time, at the bottom of the piston stroke. A large portion of the fuel/air mixture entering the cylinder from the crankcase through the intake ports goes directly out, unburned, through the exhaust port. With direct injection, only air comes from the crankcase, and fuel is not injected until the piston rises and all ports are closed.

Bajaj has already launched Three wheelers with GDi engine .The engine also meets the stringent emission norms with 50% lower carbon monoxide ((CO) and 25% lower hydrocarbons and nitrous oxides (HC+NOx) .

As said in economic times by a senior Bajaj Auto executive -

“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.”

Bajaj Auto is likely to customize the GDi technology for its two-wheeler products in the next few months. 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. In 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 in higher emission.

If that happens, i am sure that we still have a large section of youth who loves to hear that two stroke sound! Count me also!
