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

Green Car Congress

The SQ5 TDI was first introduced in the fall of 2012 as the first Audi S model powered by a diesel engine. 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. lb-ft) of torque. Many details of the V6 3.0

US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.

Study estimates the composition of non-exhaust atmospheric particulate matter from traffic

Green Car Congress

A study by a team of researchers in the UK has estimated the contributions of brake dust, tire dust, and resuspended dust to non-exhaust traffic particles as. As a result, these non-exhaust emissions make up a similar proportion of the airborne particulate matter (PM) resulting from vehicle use as exhaust emissions.

PowerDriver simulations predict thermoelectric exhaust waste heat recovery output of 300W, -2.5% in fuel consumption; prototyping begins

Green Car Congress

The European Union-funded PowerDriver project—a two-year, €3-million (US$4-million) research project initiated in February 2012 to turn exhaust gas waste heat into electricity using thermoelectric generator (TGEN) technology—has completed simulation work on on a potential automotive application.

Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. Diesel particulate filters (DPF) and urea-based selective catalytic reduction (SCR) exhaust after-treatment systems thus have emerged as feasible strategies to meet the 2010 USEPA regulations.
