Abstract

This invention discloses fuel oil ejecting system of methanol fuel engine. It includes general oil ejectors, the number of which is the same as that of air cylinders. The controlling circuit of the said general oil ejector connects to the engine electric controlling element. This system also has heating oil ejector, which connects in series with the oil orbit of oil ejector through fuel oil pipe. The fuel oil pipe controlling circuit of the said heating oil ejector connects to engine electric controlling element. This invention can effectively solve the engine low temperature cold boot question. It is safe, easy to assemble, long life span and low cost.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and relates to the power system of the automobile. More specifically, the invention relates to a low-temperature starting device for a methanol fuel engine. The invention also relates to the control method adopted by the methanol fuel engine low-temperature starting device. Background technique [0002] An important physical property of methanol fuel is that its latent heat of vaporization is 3.7 times that of gasoline, so the heat absorbed by methanol fuel when it evaporates is higher than that of gasoline, which means that it needs a higher temperature to vaporize, so the vaporization effect at low temperature is poor. , It is not conducive to cold start at low temperature, especially in the winter season in the north, methanol fuel enters the engine combustion chamber in the form of droplets, and cannot form a mixture of oil and gas, which will cause serious consequences of failur...
