Heat pump overheating of the engine backlog to the top of the piston, the combustion chamber wall, the top of the valve and the spark plug on the formation of hot coke, hot oil pump easily lead to pre-combustion of the mixture of gas. At the same time, heat pump metal parts due to high temperature thermal expansion, the smaller the gap between the normal fit of the parts. 1 engine oil deterioration engine oil at high temperature and pressure when the work, so that the deterioration of oil oxidation stability, heat pump exacerbated its thermal decomposition, oxidation and polymerization process. These are accelerated wear parts, a serious impact on the service life of the engine. This abnormal combustion, hot oil pump more serious engine overheating phenomenon, the formation of a vicious cycle, heat pump cylinder block and cylinder head easy to produce thermal deformation or even cracks, more common is to burn the cylinder liner, valve and valve seat. 2. Unusual head combustion is not normal Atmospheric temperature is high, heat pump into the cylinder of the mixture temperature is also high, the engine of the work cycle temperature is high, and radiator cooling efficiency is low, the heat pump makes the engine overheated, Combustion chamber end of the mixed gas to accept more heat, exacerbating the flame reaction, which is prone to deflagration. Engine oil is mixed with incompletely burned product, water vapor condensed by the hot oil pump, and dust entrained in the intake air, causing the oil to deteriorate. 3. The hot air pump engine reduces the inflated coefficient of the hot oil pump temperature is higher, the smaller the air density, the actual intake of the engine to reduce; because the engine overheating, engine cover temperature is higher, the engine inflated ability to reduce. In addition, because the oil temperature is high, the viscosity decreases, the oil thinning, deterioration of oil, oil pressure decreases, heat pump engine parts surface is not easy to form a lubricating film. Inflation coefficient of the hot oil pump drops, causing the engine power to drop, making the car unable to drive. In addition, due to the decrease of the aeration coefficient, the mixture becomes thicker and the concentration of harmful substances (CO, HC, NOX, soot) in the automobile exhaust increases to increase the environmental pollution.
