Audi introduces new high-efficiency 2.0L TFSI based on Miller cycle; 190 hp, 47 mpg

Green Car Congress

TFSI gasoline turbocharged direct injection engine for the first time at the Vienna Motor Symposium this week. This also addresses particulates from gasoline direct injection. The consistent reduction of friction as well as the use of low-friction engine oil (0W-20) also increases efficiency. Stansfield, P., and Freeland, P.

Ford E85 Direct Injection Boosting Study: A Less Expensive Alternative to Diesel

Green Car Congress

The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. The vehicle owner will realize high fuel economy because gasoline, with its greater eating value per volume, is the fuel that is primarily used for most driving modes.
