With the increasingly tense and the society of petroleum resources increasinglyattach importance to environmental protection, people look for new energyconstantly atthe same time, also in unceasingly develop new technology to reduceemissions andimprove fuel economy of engine combustion. Therefore, this paper will single cylindergasoline engine modified for natural gas engine for power generation, research on theperformance and the control system of the before and after modification of the engine.Based on the AVL-BOOST software research on gasoline engine modifiedfornatural gas engine, different ratio of gas, different compression ratios anddifferentinfluence of ignition advance angle of the engine performance, and on the basisofengine working characteristics to choose an optimal operating point. Use theAltiumDesigner design and Simulation of the natural gas engine control systemhardwarecircuit. The power supply circuit design and interface required for distributionof the single chip microcomputer. The temperature sensor, pressure sensor, oxygen sensor,a control circuit and ignition control circuit design and simulation analysis.SoftwareMPLAB software for electronic control system based on IDE was designed,which basedon the Proteus microcontroller simulation software of control systemsoftware simulationanalysis.The simulation results show that, the general market sales of natural gas used as fuel,compression ratio11, ignition advance angle20°, the performance of the engine is themost excellent. The design of hardware and software of control system has reached thedesign requirements.
