It is shown that with adjusted ignition Angle of advance, larger compression ratio and appropriate preheating of the mixture, better fuel economy can be achieved.
指出调整点火提前角、提高压缩比以及适当预热混合气等，可以提高掺烧甲醇时燃油的经济性。

The problem of longer ignition delay for hydrocarbon fuel can be effectively solved by means of preheatingfuel by shock waves and using hot gas as pilot.
All the other premise parameters are unchanged except further raising the dome temperature by preheating the fuel gas with the heat recovered from waste gas.
