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.

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

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

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.
