The Experimental Study Of Fuels Stead Of Gasoline In The Electronic Controlled Fuel Injection Gasoline Engine

Based on the environment protection ,in the paper the pivotal technique of LPG, Methanol-gasoline and the sanitary naphtha used in the electronic controlled fuel injection gasoline engine is studied, it is investigated synthetically how the component of LPG and the capability of engine were optimally matched in the electronic controlled fuel injection gasoline engine which is of a great number used in china. The factor influencing the capability of the LPG-gasoline dual-fuel cars used in the low temperature condition is analyzed detailedly. In different environmental temperature the engine experiment of LPG in the different component is investigated along with the experiment of the whole car ,the optimum component of LPG adapt to the low temperature condition of the north area was brought forward at last. The experimental studies on the mixed fuel of gasoline with middle methanol content are carried out, the engine experiment of methanol-gasoline hi the different component (M30, M40, M50) was analyzed detailedly along with the experiment of the whole car .The experimental studies on the sanitary naphtha are carried out, the property of use of the new fuel is investigated detailedly .Through comparing with gasoline in the same condition hi the properties of dynamics and economy and emission ,find the advantages and disadvantages of three fuel ,so that people can comprehend their the property of use and select the right fuel according to requirements.
