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 ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

Improved liquid hydrogen-powered Corolla and GR86 (carbon-neutral fuel) to participate in Super Taikyu at Autopolis

Green Car Congress

The hydrogen-powered Corolla, mobile liquid hydrogen stations, and carbon neutral fuel have evolved in the two months since the Round 2 NAPAC Fuji SUPER TEC 24 Hours Race from 26-28 May. In addition, pump stress has been reduced by optimizing fuel pressure, leading to a weight reduction for the pump drive motor battery.

MAN ES reports Tier III exhaust-after-treatment orders for low-speed engines pass 1,000

Green Car Congress

Approximately one-quarter of the orders have been for EGR (Exhaust Gas Recirculation) systems, with SCR (Selective Catalytic Reduction) systems accounting for the remainder. The milestone was passed in early January 2021 and is built upon references from the company’s portfolio of ME-B, ME-C and MC-C fuel-oil engines.

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.
