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.

Auckland Transport begins 2-year trial of hydrogen bus

Green Car Congress

It has a range of some 400 km (249 miles). Auckland Transport has also advanced its zero-emissions target from its vehicle exhausts to 2030, from an earlier target of 2040, subject to council funding. The bus is fitted with a Ballard fuel cell and ZF drive system. The bus will be refuelled at the Ports of Auckland with green hydrogen.

OECD report finds measures needed to curb PM emitted by wear of car parts and road surfaces, including EVs

Green Car Congress

Wear and tear from brakes, tires and road surfaces will soon overtake car exhaust fumes as the leading source of fine particles released into the air by road traffic, according to a new OECD report. Heavy electric vehicles with long-distance batteries could compound the problem even as they slash emissions from engine exhaust.

The exhaust gas contains significantly less carbon monoxide and nitrogen oxides (NO x ), while the share of soot or particulates is minimal. The total CNG tank capacity is currently 115 liters or 17.3 These are added to the fuels.

Cummins progressing toward ATLAS Tier 2 Bin 2 fuel-efficient diesel for light-duty pickups

Green Car Congress

US Light Duty Diesel Emission Standards (full useful life: 150,000 miles). Tailpipe emissions [g/mile]. The HP loop recirculate exhaust from exhaust manifold to intake manifold via an HP EGR valve; there is no physical EGR cooler in the HP loop. AN exhaust throttle and LP EGR valve work together to control mass flow rate.
