Federal-Mogul Introduces New Diesel Piston Design to Support Downsized Engines with Higher Output

Green Car Congress

Federal-Mogul Corporation has developed an innovative aluminum piston design that can reliably withstand the mechanical and thermal loads produced by heavily boosted engines, thereby enhancing diesel engine performance and supporting diesel downsizing. The grain size of the re-melted part is approximately one tenth of the as-cast size.

CPT VTES Electric Supercharger Selected for Two Projects

Green Car Congress

When applied to a radically downsized 1.2-liter liter naturally aspirated engine, the downsized engine with electric supercharger reduces the 70-100 km/h (44-63 mph) top gear acceleration time from 18 to 11 seconds. More than 90% of the available torque is delivered in less than a second. Compared with a 1.6-liter
