Federal-Mogul marine piston ring technology reduces oil consumption and pollution from two-stroke diesels

Green Car Congress

Federal-Mogul Powertrain, a division of Federal-Mogul Holdings Corporation, has developed a new piston ring for two-stroke diesel engines that reduces oil consumption and marine pollution by allowing the quantity of lubricant used to be greatly reduced. This feed oil is not uniformly distributed on the cylinder wall. Click to enlarge.

For our own security it’s time to ditch oil dependency

My Electric Car

It’s been obvious for a long time that our position in Australia is rather precarious when it comes to our reliance on oil. The drone attacks on the Saudi oil fields brought this point into sharp focus over the past few days. We rely on foreign liquid fuel imports for 85% of our needs (and climbing). It no longer serves us well.

Fraunhofer developing process to ferment steel exhaust gases to fuels and chemicals

Green Car Congress

Fraunhofer researchers in Germany have developed a process for the conversion of CO-rich exhaust gases from steel plants into fuels and specialty chemicals. In addition to the exhaust gases, syngas—similar gas mixtures from home and industrial waste incineration—can also be used for the engineered process.

Researchers develop viable catalysts for reforming of heavy gas oil to hydrogen

Green Car Congress

Less refined fuels—such as heavy gas oil—would be less expensive; however, the higher levels of sulfur in the fuels could prove problematic for catalysts. One approach to overcoming such limitations is the use of direct reforming of gas oil (heavy hydrocarbons) over a heteroatom-resistant catalyst. Now, researchers in S.
