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).

Continental to supply turbochargers for new Ford 1.0L EcoBoost engines

Green Car Congress

Developed for the latest 1-liter downsized gasoline engines. The successful collaboration with Ford resulted in a turbocharger design that meets the particular technical challenges posed by small, downsized engines. Click to enlarge. Earlier post.) The first two engines will generate 74 and 88 kW from a displacement of just one liter.

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.

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.
