Audi presents latest SQ5 TDI diesel; 48V MHEV & electric compressor

Green Car Congress

An actuator in the exhaust system, as fitted to the first SQ5 TDI, gives the V6 a sonorous sound. This offers the advantage since exhaust gas cleaning responds more quickly. The exhaust manifold benefits from improved insulation; the exhaust gas reaches the optimum temperature more quickly after a cold start.

Toyota Central R&D developing free-piston engine linear generator; envisioning multi-FPEG units for electric drive vehicles

Green Car Congress

Toyota’s FPEG features a hollow step-shaped piston, combustion chamber and gas spring chamber. Toyota envisions that a pair of such units (20 kW) would enable B/C-segment electric drive vehicles to cruise at 120 km/h (75 mph). The FPEG consists of a two-stroke combustion chamber, a linear generator and a gas spring chamber.

ICCT-led test of 73 Euro 6 diesels finds large difference in NOx results under NEDC and more realistic WLTC

Green Car Congress

The three main NOx control technologies currently on the market are exhaust gas recirculation (EGR); lean-burn NO x traps (LNT); and selective catalytic reduction (SCR). EGR systems recirculate a portion of exhaust gas to the combustion chamber, lowering the combustion temperature and the production of engine-out NO x.
