Efficiency Improvement of Electric Generating Engine System Based on Internal Combustion Engine: Energy Simulation of New Engine Operation with Electric Generator and Motor

摘要

An internal combustion engine with a crank mechanism moves with its piston and load mechanism interlocked, and this poses a problem for efficiency improvement. We therefore built a system in which the piston and load mechanism linearly; a generator is used in the combustion stroke and a motor is used in the exhaust, intake, and compression strokes. This system can control piston motion freely, so generation energy and consumption energy in each stroke can be optimized. To check its effectiveness, we developed a simulator in which an engine mechanism and motor/generator is integrated, we performed an energy simulation, and we verified the effectiveness of the method of operation of the proposed system.
