Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

Blending 25-50% of this low-temperature ethanol reformate with ethanol or E85 fuels enables dilute engine operation, resulting in substantial improvements in fuel economy and emissions. Unlike high-temperature reforming, supplementary water is not required. —Sall et al.

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.

Hyundai showcasing new downsized turbo engines and 7-speed dual-clutch transmission; i40 48V Hybrid, i30 CNG

Green Car Congress

The new engine comes with an electronically-controlled waste-gate to optimize flow and improve low-end torque and throttle response. To keep the engine unit as small as possible, the exhaust manifold is integrated within the cylinder head and can therefore be cooled efficiently using the cylinder head water cooling system.
