Direct injection is becoming standard on more and more late-model vehicles in both gasoline and diesel versions.

The 1.4-liter gasoline engine is one of Volkswagen’s latest EA211 series of small engines.

The LT1 now features direct injection, AFM (Active Fuel Management), continuous variable valve timing, and a new combustion system that incorporates 11.5:1 compression ratio. The LT1 combustion system is the most intensely analyzed, developed and optimized system in GM history.
