Jaguar adds two new smaller forced induction gasoline engines to 2013 XF and XJ lineup; 8-speed automatic and start-stop

Green Car Congress

For the 2013 XF and XJ lineup, Jaguar is adding two new downsized forced induction gasoline powerplants: 3.0-liter It achieves this through a combination of technologies which results in peak power of 240 PS (237 hp, 177 kW) at 5500 rpm and 340 N·m (251 lb-ft) of torque available between 2000 and 4000 rpm. liter i4 and 3.0-liter

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

Due to the lower exhaust enthalpy of lower temperature engines using PPCI, it is difficult to produce intake boost with acceptable boost system parasitis. A practical powertrain system with robust PPCI combustion is needed, including injection, valvetrain, boost, and exhaust subsystems. Camtronic 2012. i-DTEC Diesel 2012.

Brunel engineers optimizing CAI combustion in 2-stroke camless gasoline DI engine

Green Car Congress

Many approaches have been attempted to achieve CAI operation on the four-stroke spark ignition engines, such as intake air heating, high compression ratio, dual fuel, recycling the exhaust gas, and so on. To minimize the air short-circuiting rate, the intake and exhaust valve timings were adjusted. Earlier post , earlier post.).
