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. ADEPT will use CPT’s SpeedStart micro-mild hybrid (BSG and stop-start) and TIGERS energy recovery systems.

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

Green Car Congress

The wet start-up clutch replaces a conventional torque converter, and helps to save fuel. The eight-cylinder biturbo engine also features the generator management system from the E 63 AMG: whenever the engine is on the overrun or when braking, kinetic energy is used to charge the battery rather than being wasted as heat in the usual way.
