Abstract

Disclosed is a dimethyl ether city bus fuel-oil module supply system which is mounted on the tail part of the bus; the module supply system comprise a mounting bottom plate; a booster pump, a pressure gauge I, a filter cleaner, a stop valve I, a tank storage group, a stop valve II, a condenser, a check valve, a nozzle reflow electromagnetic valve, an overflow valve, a pressure gauge II and a fuel-oil pump reflow electromagnetic valve are all mounted on the mounting bottom plate. The parts are connected through pipelines and round joints; the pipeline adopts the stainless steel pipes; the stainless steel pipes are connected with the round joints through braze welding. The dimethyl ether city bus fuel-oil module supply system has the advantages of adopting the module design, performing production, centralized inspection, rapid and convenient mounting, convenient popularization, convenient repeated assembly, disassembly and good air-tightness due to the round joints applied in the parts.

Description

technical field [0001] The invention relates to the technical field of automobiles, internal fuel oil and power machinery, relates to a supply system for dimethyl ether used in compression ignition engines, and in particular to a fuel modular supply system for dimethyl ether city buses. Background technique [0002] The oil resources in the world can still be exploited for 40 years, but in our country it is only 15-20 years. The research and application of petroleum alternative fuels is imminent. [0003] DME has a high cetane number and contains 34.8% oxygen. When used as an alternative fuel, NO X The emission is only about 30% of that of diesel fuel, and it can realize smokeless combustion in the full range of speed and load, and can meet Euro III and U.S. ultra-low emission (ULEV) standards, so it is an excellent environmentally friendly alternative fuel. DME can be directly synthesized by one-step method from coal vaporization, and has a wide range of sources. The cost ...
