Hybrid vehicles with radial engines

摘要

A radial cam engine with an optimized cam configuration can provide improve performance over crankshaft internal combustion engines. The cam configuration can include a flat-top or flat bottom piston motion, multiple lobe cam configurations, matching piston force with torque/force ratio in combustion phase, asymmetry piston motions for improved power transfer during combustion phase, and/or offset piston and cam configurations. The radial cam engine can be used in vehicles, such as hybrid vehicles.

1. A hybrid vehicle comprising
an electric motor configured to drive the hybrid vehicle,
wherein the electric motor is powered by an battery; a radial cam internal combustion engine configured to drive the hybrid vehicle,
wherein the radial cam engine is powered by a non-battery power source,wherein the radial cam engine comprises a piston,wherein the radial cam engine comprises a cam coupled to a camshaft,wherein the cam is configured to provide a substantially flat-top piston motion,wherein the cam is configured to provide a substantially flat-bottom piston motion,wherein the cam is configured to provide a force profile of the piston that is substantially similar to a torque/force ratio profile of the camshaft at least in a first duration, wherein the first duration is between a top-dead-center position of the piston to an inflection point of the piston motion.
