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.

Use of a Low-Cost Electric Supercharger Could Significantly Reduce Smoke from Turbocharged Diesel Engines

Green Car Congress

It is commercializing three initial products: Variable Torque Enhancement System, VTES, an electric supercharging system; SpeedStart12, an integrated belt-driven starter generator system; and TIGERS, an exhaust turbine-driven generator system. It can also help minimize the need for expensive exhaust after-treatment. Earlier post.).
