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. Low pressure EGR (exhaust gas recirculation).

ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%

Green Car Congress

Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation. Using the virtual simulation environment GT-Power, this cycle is applied to a 4-cylinder SI engine.

CPT launching water-cooled electric supercharger for commercial diesel engines

Green Car Congress

Cobra could enable a 5–10% reduction in CO 2 emissions when implemented in conjunction with engine downsizing and down speeding strategies, and potentially more when used in conjunction with alternative fuels, according to CPT. Unlike a turbocharger, Cobra is not dependent on the exhaust gases flowing to do its work.

Federal-Mogul expands powertrain materials portfolio for more efficient heavy-duty diesel engines

Green Car Congress

A heavy-duty exhaust valve guide with thermal deformation and temperature color scaling demonstrates high side load at high temperatures in contact with the exhaust gas. Federal-Mogul’s new advanced turbocharger bushing materials provide enhanced wear performance at elevated temperatures and in highly corrosive environments.
