Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode.

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

Green Car Congress

The Ricardo-led Advanced Diesel Electric Powertrain (ADEPT) project will apply 48V “intelligent electrification” concepts, mild hybridization and waste heat recovery in a Ford Focus diesel demonstrator. In 2011, the HyBoost team reported that the HyBoost demonstrator was achieving comparable performance to the conventional 2.0L

Downsized 5.5L V8 Biturbo in S 63 AMG Delivers 25% Fuel Savings Compared to Predecessor; Stop-Start is Standard

Green Car Congress

In addition to its twin turbos, the new eight-cylinder unit—known internally as the M 157—features gasoline direct injection with spray-guided combustion and twin turbochargers. The wet start-up clutch replaces a conventional torque converter, and helps to save fuel. AMG has developed a 5.5-liter The new AMG 5.5-liter

GM to double models with 40 mpg highway or better by 2017; ongoing manufacturing efficiency improvements

Green Car Congress

The company is also the thermodynamic efficiency of gasoline engines using a suite of technologies that include downsizing, turbocharging, direct injection, variable valve timing and cylinder deactivation. By recycling and reusing 90% of its manufacturing waste worldwide, the company generates about $1 billion in revenue annually.

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.

Optimizing a CNG-Fueled Spark Injection Engine for a Parallel Hybrid Powertrain

Green Car Congress

In recent years two methods, namely downsizing and downspeeding, were established on the market to reduce CO 2 emissions while maintaining the driving performance of engines with identical effective power but a larger displacement. The exhaust manifold and upstream catalytic converter was replaced by a manifold with a turbocharger flange.
