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

Green Car Congress

Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L Skarke et al.

Downspeeding and supercharging with transmission optimization can deliver fuel economy improvement over downspeeding and turbocharging

Green Car Congress

The downsped supercharged configuration also retained the first gear acceleration, top gear passing, and 0-60 mph acceleration of the baseline turbocharged vehicle. Engine downsizing and downspeeding are two strategies that can be applied to gasoline and diesel engines to improve vehicle fuel economy. —Ostrowski et al.

Rotrak testing prototype variable drive supercharger in vehicle on dyno

Green Car Congress

In a 2010 paper, Roger Stone, Engineering Director, Torotrak noted that conventional turbo- and supercharging technologies are more than capable of delivering the required peak power and torque levels from downsized engines but suffer from a number of. It gives the next generation of downsized powertrains ‘big-engine’ response.

Update on the ACCESS fuel efficient engine project; simulations find up to 48.9% improvement in fuel economy over baseline

Green Car Congress

To achieve the target fuel economy improvement over the baseline V6 configuration, the team used GTDI technology for downsizing in combination with part-load lean homogeneous charge compression ignition (HCCI) operation for further fuel economy gains. V6 accelerates from 0-60 mph in 5.5 The project team is replacing a 3.6L Wheeler, J.,
