Key advances for Gen 3 are in weight reduction, friction reduction, and the internal exhaust cooling system. Volkswagen first launched the EA888 engine generation in spring 2007 (Gen 1). Improvements contributing to this better fuel economy come from many areas. Generational progress with the EA888. liter engine.

In that study, they found that fuel economy and power output can both be improved by increasing the compression ratio and applying exhaust gas recirculation (EGR) under low loads and by lowering the compression ratio and applying higher boost pressure under high loads. (In VC-T technology is a step change for Infiniti.

Even a highly efficient combustion engine converts only about one-third of the energy in the fuel into traction actually propelling the car. The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. Click to enlarge. No more cold starts.
