Electric-cooling liquid mixed fuel heating system

Abstract

The invention relates to an electric-cooling liquid mixed fuel heating system which is characterized in that: an electric heater is arranged on an oil suction pipe and an oil return pipe on an oil tank assembly, an oil pipeline of a heater, a rough filter and a fine filter; one end of the oil pipeline of the heater is connected with the heater; the other end of the oil pipeline of the heater is connected with the oil suction pipe; a heating bushing is arranged between the oil return pipe and an engine; heating bushings are arranged among the rough filter, the engine and the oil suction pipe; the detailed method is as follows: the oil suction pipe and the oil return pipe on the oil tank assembly, and the oil pipeline of the heater are firstly heated by electricity; the cooling liquid of the engine is heated after the heater works; the heated cooling liquid of the engine enters the heating bushings to heat the diesel oil in the inner pipes of the intake and oil return pipes of a whole vehicle; meanwhile, the rough filter and the fine filter are heated by electricity; after the engine is smoothly started and runs stably, a valve is closed, and heating to the diesel through the cooling liquid is stopped. The electric-cooling liquid mixed fuel heating system improves the low-temperature cold start performance and environmental adaptive capacity of the engine. Moreover, corresponding low-brand diesels can be used, and the use cost of users is reduced.

Description

technical field [0001] The invention relates to a fuel heating system mixed with electricity and coolant, which is a brand new fuel heating system. Background technique [0002] This system is currently blank in China, and the existing domestic fuel heating adopts a single electric heating or coolant heating method. The heating effect of this method has limitations. It cannot heat the fuel to an ideal flow state when it is cold started in a low-temperature environment, so the diesel oil has poor fluidity, and sometimes even waxes, which often causes difficulty in starting the engine, sometimes it cannot be started, and sometimes it stops suddenly during driving. . Contents of the invention [0003] The purpose of the present invention is to provide an electric and coolant mixed fuel heating system, which solves the problem of low-temperature cold start of commercial diesel vehicles by combining electric heating of diesel oil and engine coolant heating of diesel oil.
