Federal Mogul develops advanced aluminum piston for high-performance light-duty diesel engines

Green Car Congress

The piston’s raised gallery places the cooling oil as close to the piston bowl as possible to achieve maximum cooling. downsized diesel engines with improved fuel economy and CO 2 emissions. Federal-Mogul's 2D ultrasonic inspection technique enables high performance pistons for diesel downsizing. internal friction. its strength.

Pinnacle 4-stroke opposed-piston SI engine shows fuel economy improvements of between 30-60% at light loads, 12-30% at medium loads over conventional

Green Car Congress

The results represent a light-load indicated efficiency improvement of 15-30% (up to 40.9%). The sleeve valves have a short heat rejection path directly to lube oil. During the valve open event, all but the top few millimeters are drawn past a lip seal into oil. There is no ISFC improvement at high load. Active sleeve cooling.

Downsized 4.0 TFSI for Audi S8 cuts fuel consumption 23% compared to predecessor; cylinder deactivation and start-stop

Green Car Congress

Weighing 220 kilograms (485 lb) including all key add-on parts, the V8 is comparatively light. Audi’s principle of downsizing: “ Forced induction replaces displacement ” One twin-scroll turbocharger per cylinder bank compresses the fresh air. The demand-controlled oil pump varies oil pressure in two stages.

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Alcohol-based transportation fuels from a wide range of biomass feedstocks including agricultural, forestry, municipal and industrial waste and specially grown crops and trees can potentially offer a substantial substitute for oil derived fuel. More modest downsizing up to 5 liters could offer a practical solution. In this manner a 3.6
