Dedicated Hybrid Cycle Based Motive Powerplants for Electrifying Off-Highway Vehicles

With quickening paces of transportation electrification, an innovative DHC (Dedicated Hybrid "Cycles (Combustion)" ) is developed to reconceive motive powerplants for transformative vehicle electrification. The energy-efficient DHC technology can reconfigure existing powerplants with low performaing Otto cycles to more than double the power density with remarkably less harmful pollutants. The proposed electrification technology provides a feasible solution to hard-to-electrify segments such as agriculture. We do envision that the synergy of DHC based electrification with carbon circular bio-fuels would be able to solve the puzzle of "the heavier vehicles, the more emissions, but the harder to electrify".
