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.

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.

Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Green Car Congress

Before they can be used, however, it is essential to understand their physical properties, combustion chemistry, and characterization of the exhaust due to a number of issues associated with fuel properties—for example, a lower heating value and higher cloud point than regular diesel. Kumar et al.
