Federal-Mogul hybrid liner for cylinders reduces bore distortion and improves function in lighter, downsized engines; up to 40% reduction in oil consumption

Green Car Congress

Dynamic strength increases as well; in a cyclic pulsing pressure test, the Hybrid Liner showed no failure at pressures of up to 200 bar, whereas a standard liner block design cracked at 100 bar. Conventional liners can allow water to seep down the joint between liner and casting, reaching the crankcase and contaminating the lubricating oil.

Audis A1 to Launch With Four Engine Options; Energy Recuperation and Stop-Start Standard

Green Car Congress

Audi will initially offer the A1 with four engines; the two TFSI gasoline engines and the two TDI diesels cover a power range from 63 kW (86 hp) to 90 kW (122 hp). This downsizing concept coupled with energy recuperation and stop-start technologies from the Audi modular efficiency platform give them fuel consumption ranging from 3.8
