| Abstract: | Optimum calculation and research have been carried out for gasolene engine work-ing process by means of restrained variable dimension method,and WT(variable valve timing)andVCR(Variable compression ratio)methods ars explained. Result of the research shows that fuel e-conomy of gasolene engine may be sufficiently improved by combining VVT method and VCRmethod with optimum ignition advance angle,and potentiality of WT method and VCR methodmay be exploited out to the greatest extent. |
