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. liters (0.2

Researchers developing free-piston linear generator for exhaust waste heat recovery

Green Car Congress

Researchers in China have developed a novel free-piston linear generator (FPLG) to recover exhaust waste heat efficiently from a vehicle engine. The FPLG can be used in a small-scale organic Rankine cycle (ORC) system and can directly convert the thermodynamic energy of working fluid into electricity. —Tian et al.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

An electrically driven compressor for precise exhaust gas recirculation is also used. The research project is co-financed by the Swiss Federal Office of Energy (FOEN). Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption. —Patrik Soltic.
