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.

Germany launches new study of oxymethylene ethers for optimizing clean diesel combustion

Green Car Congress

Due to their high oxygen concentration, they suppress pollutant formation in combustion. Further development of diesel and gasoline fuels now offers the chance of preventing the formation of hazardous exhaust gases directly at their origin, i.e. during combustion in the engine. Ford is currently leading a €3.5-million million (US$3.9-million)

Small-displacement two-stroke H2 engine could address performance and emissions cost-effectively for recreational market; potential for Asian motor vehicle fleet

Green Car Congress

It, or a scaled-up version, could also provide a solution for the Asian motor vehicle fleet, in which two-stroke engine vehicles constitute a major share—and contribute significantly to air pollution. Everything else—pistons, porting and crankcase, bearings, exhaust, etc.—were Oh and Plante. Click to enlarge.

Perspective: Europeans in the lead with range extenders for hybrid vehicles; 2nd vs. 3rd generation

Green Car Congress

The “ Electric Vehicles—Land, Sea & Air Europe 2011 ” conference and exhibition will take place in Stuttgart, Germany 27–28 June. The company is also producing a US variant of the conference in San Jose, California in November. These second generation engines retain piston-driven, internal combustion technology.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For offsets to be credible, a ton of CO 2 -equivalent emissions from an offset project should equate to a ton reduced from a covered emission source, such as a smokestack or exhaust pipe. To be credible, as noted above, an offset should equate to an emission reduction from a direct emission source, such as a smokestack or exhaust pipe.
