Description

technical field [0001] The invention belongs to the field of low-temperature start-up and preheating of motor vehicles, and relates to a low-temperature preheating device for motor vehicles. The fuel system is heated. Background technique [0002] In the plateau or cold area, subject to the influence of low-temperature environmental factors, the temperature in the cab is very low, and the driver's working environment is very harsh; the heat transfer of the cylinder itself increases, and the temperature of the air entering the cylinder is also low, making it difficult to catch fire; The lubricating oil in the engine oil pan is in a cooling state, the viscosity increases, and the fluidity becomes poor, which leads to increased wear of the parts in the engine, and even causes cylinder scuffing; the diesel oil in the oil supply system also becomes fluid due to the increase in viscosity. Poor, the use of low-grade diesel oil will often cause thickening and waxing of diesel oil, ...
