Abstract
In accordance with the characteristics of the power system of engineering machinery vehicle and its fuel consumption characteristics, its cooling system and fuel supply system are optimized through research and test based on operating modes of diesel engine to ensure that the vehicle is reliable and safe in the case of sudden changes in low temperature environment, cold environment or natural environment. Specifically, it is required to insert heating pipe through oil tank or install thermal insulation radiator at the bottom of the tank. In a word, the optimization is based on heat exchange principle, i.e., using the heat generated by the cooling system of diesel engine to heat the fuel tank to avoid diesel freezing in tube and tank, further improving fluidity of diesel at low temperature to ensure normal operation of diesel engine, and improving vehicles' power performance and energy economy to reduce emissions.关键词
