US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.

Swiss team concludes that particulate filters should be mandatory for GDI engines

Green Car Congress

Empa researchers Norbert Heeb and Maria Munoz discovered large quantities of benzo(a)pyrene (red bar)—a combustion product responsible for cutting short the lives of cigarette smokers—in the exhaust gas emitted by GDI engines. Levels in exhaust emissions were found to be as much as 1,700 times above this limit.

Clemson research developing integrated modeling and control systems to reduce particulates from GDI engines

Green Car Congress

Onori notes that an integrated approach to reduce gasoline particulates is necessary because engine operating conditions determine oxygen and fuel content and temperature of the exhaust gas, which influence the output of the catalytic converter, which in turn governs soot accumulation and oxidation in particulate filters.
