Study estimates 6% of lung cancer deaths in US and UK attributable to diesel exhaust

Green Car Congress

In 2012, the International Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), classified diesel engine exhaust (DEE) as carcinogenic to humans (Group 1). However, emission standards for offroad vehicles and industrial applications are generally introduced after those for on-road vehicles and therefore many offroad applications were still largely uncontrolled in 2000.

New 1.6L diesel in 2018 Chevrolet Equinox related to Opel’s 1.6L CDTi Whisper Diesel

Green Car Congress

Fuel pressure is 2000 bar (29,000 psi). A variable-vane turbocharger enables the engine to deliver more power with lower exhaust emissions and no decrease in overall fuel efficiency. NO x emissions are controlled via a Selective Catalyst Reduction (SCR) after-treatment system that uses urea-based Diesel (Emission) Exhaust Fluid (DEF). The new 1.6-liter diesel engine to be offered in the US in the 2018 Equinox ( earlier post ) is similar to Opel’s 1.6L
