SwRI simulations show turbocharged Scuderi Engine could reduce a standard 2011 Nissan Sentras fuel consumption by up to 35% on FTP cycle

Green Car Congress

Modelled results of fuel consumption in 2011 Nissan Sentra. At the onset of the study, a computer baseline model of the Sentra was established, which closely matched the measured performance of the actual 2011 Nissan Sentra. Source: Scuderi. Click to enlarge. Preliminary results showed up to a 25% decrease in fuel consumption (i.e.,

Scuderi working on turbocharged variant of split-cycle engine; smaller, more powerful, and more fuel efficient

Green Car Congress

The Scuderi Group announced at the SAE 2011 World Congress in Detroit that boosting one of its air-hybrid split-cycle engines ( earlier post ) with a turbocharger to 3.2 You can either feed [two expansion cylinders] or the logical, more simple approach is that you downsize the compression cylinder.

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.

ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

This combined combined aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance and a 12+X volt micro-hybrid stop-start and energy recuperation systems. In 2011, the HyBoost team reported that the HyBoost demonstrator was achieving comparable performance to the conventional 2.0L

The thermal electric generator then converts the wasted heat into useful electrical energy to help power auxiliary systems. Producing 98g/km of CO 2 emissions, the i20 blue is scheduled to go into production in 2011. The new, downsized 1.0-liter Adaptive aerodynamic features also increase fuel efficiency.
