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 develop effective exhaust catalyst for lower temperature exhaust

Green Car Congress

To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of waste heat in the exhaust. As a result, future generations of exhaust after-treatment catalysts must perform at temperatures that are 100 °C lower than current catalysts. —Nie et al.
