First online measurement of gaseous sulfuric acid in diesel exhaust helps clarify role in formation of nucleation particles

Green Car Congress

Researchers in Germany and Finland report the first online measurement of gaseous sulfuric acid (GSA) in the exhaust gas of a modern heavy-duty diesel engine in an effort to quantify the role of low-vapor-pressure gases in the formation of nucleation particles (NUP). of hydrocarbons) significantly. of hydrocarbons) significantly.

Study finds diesel oxidation catalyst eliminates mutagenicity of diesel exhaust in gas phase

Green Car Congress

A team of researchers in Germany has found that the mutagenicity of diesel engine exhaust (DEE) is eliminated in the gas phase by a Diesel Oxidation Catalyst (DOC), but only slightly reduced in the particle phase. This can be achieved by direct measurement of the exhaust components.

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.

Cummins to purchase SCR doser assets from Hilite International

Green Car Congress

Air-assisted components use onboard compressed air to precisely dose the reduction medium into the exhaust pipe. This can only be achieved through a match between the reductant spray and the exhaust gas flow. The exhaust aftertreatment system needs to be up and running quickly, even under freezing conditions, for all applications.

SwRI launches Particle Sensor Performance and Durability consortium

Green Car Congress

Sensors that trigger engine malfunction illumination light (MIL) or a fault code when particle emissions exceed a certain threshold downstream of an exhaust diesel particle filter (DPF) will soon be required to meet California Air Resources Board (ARB) and US Environmental Protection Agency (EPA) on-board diagnostics (OBD) regulations.
