A study by researchers at the University of Birmingham in the UK has found that while Diesel Oxidation Catalysts (DOCs) and Diesel Particle Filters (DPFs) has been very effective in controlling the tailpipe emissions of solid particles, there has been little change in the liquid mode ( 104 cm −3 /24-hour mean) defined by WHO. 2023.107888

Regulatory regimes seeking to reduce emissions from transport have largely focused on tailpipe emissions—i.e., the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. Non-exhaust PM factors include tire wear, brake wear, road surface wear and resuspension of road dust. earlier post ). Background.

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

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.

The researchers found that biodiesel has many advantages over regular diesel even in a very low blend percentage, including low emissions of particulate matter, combustion elements (mainly sulfur), elemental carbon, and carbon monoxide. Biodiesel may produce high NO x emissions. Kumar et al.
