Renault 2010 Environment Workshop, Part 1: Combustion Engine Technology and Product Plans

Green Car Congress

Renault held a “2010 Environment Workshop” last week to showcase its progress across its range of vehicles’ full lifecycle through the Renault eco² program. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines. New-generation 1.5 dCi engines.

Dearman begins on-vehicle testing of Gen 2 transport refrigeration system powered by liquid air engine; lighter, more efficient

Green Car Congress

Working with its technology partner Hubbard Products ( earlier post ), the entire refrigeration system has also been reconfigured, downsizing a number of components and optimizing them to deliver maximum efficiency and higher levels of performance. The only emission back to the atmosphere is air or nitrogen.

DOE to award $7M to accelerate fuel and engine co-optimization technologies; Co-Optima initiative

Green Car Congress

Groundbreaking research in the last 10 years has identified combustion engine strategies that—especially if optimized to run on new fuels—would offer significantly higher efficiency and produce fewer engine-out pollutants than current engines. Fuel research will focus on low-GHG advanced biofuel/petroleum blends.

A Dumbed Down Copenhagen For the Age of Stupid. It’s Time to Reach & Teach, Tell & Sell

Creative Greenius

With President Obama and the rest of the leaders of the world’s biggest polluting nations kicking the ball down the field on climate change and effectively pulling the rug out from under all of us who have been targeting the Copenhagen climate talks as the moment we must seize, our response must recognize the obvious. C= Closing.

Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

It is a high octane fuel with combustion characteristics that allow engines specifically designed for methanol fuel to match the best efficiencies of diesels while meeting current pollutant emission regulations. It is a safe fuel. The toxicity (mortality) is comparable to or better than gasoline.
