Researchers in Nigeria say water in diesel emulsions could significantly reduce nitrogen oxides and particulate emissions without major engine redesign. The approach may also preserve, and sometimes ...

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions ...

A new study says the reduction in emissions in the newest clean-diesel engines has exceeded the amount required by law. The study by the Coordinating Research Council in cooperation with the Health ...

The diesel engine has undergone a significant evolution over the past two decades. Most of these changes were designed to reduce emissions and air pollution, but once early generation emission goals ...

Sophisticated electronic controls and fuel systems improve combustion efficiency and substantially cut emissions. Sophisticated electronic controls and fuel systems improve combustion efficiency and ...

Volkswagen promises significantly cleaner diesel engines by using regenerative diesel fuels. The CO2 emissions can be reduced by a whopping 95%. No word on the NOx emissions, though. The company ...

Kasmer s hydristor is drawing interest from heavy equipment makers. Tom Kasmer believes he can save the Earth with the power of hydraulics. The Binghamton, N.Y.-based inventor wants to use his ...

Fuel injector cleaner serves an important function in vehicle maintenance. Most vehicles sold today have fuel injectors. Those injectors work by delivering precise amounts of gasoline or diesel fuel ...

INDIANAPOLIS—While clean energy is the future, diesel will primarily power trucking’s near future. But as more U.S. fleets face a patchwork of regulations nationwide, planning will be imperative. “The ...
