CPT presenting two papers at SAE World Congress on SpeedStart and TIGERS for 48V mild hybrid systems

Green Car Congress

Within the SpeedStart design water-cooled power and control electronics are housed within the rear of the machine to reduce cost, improve control response times and minimise losses in the power electronics. The exhaust gas can reach temperatures greater than 900 °C, whereas the turbine upper functional limit is 850 °C.

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

Green Car Congress

Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines.
