New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). Cutting off at 23 nm avoids these ‘semi-volatiles’, whereas 6 nm is a much more comprehensive range. This shows that 13.4

Mercedes-Benz Trucks launching 3rd generation of OM 471 heavy-duty diesel

Green Car Congress

With the third generation of the OM 471, Mercedes-Benz Trucks is introducing two new turbochargers developed and manufactured in-house which are precisely adapted to the broad range of customer requirements. Reduced friction losses and pressure control with low-viscosity oil. Newly-developed exhaust gas aftertreatment system.

One of the decisive factors for this performance is the VTG turbocharger, which optimizes the dynamic response in the off-road-specific speed ranges thanks to its variable turbine geometry (VTG). In addition, this technology displays the maximum power and torque over a wide speed range.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

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

Green Car Congress

In cooperation with a major European supplier, a new oil-lubricated common-rail pump had therefore been developed. An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption.
