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.

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. Active-WG control is used for improvements at all engine speeds (< 5500 rpm). is successful.
