Engine overheating caused by the adverse phenomena: 1. Hot oil pump engine inflation coefficient is lower Hot oil pump temperature is higher, the smaller the air density, the actual intake of the engine to reduce; due to engine overheating, the hood temperature is higher, the engine charge capacity decreased . Inflation of hot oil pump decreased, resulting in decreased engine power, making the car unable to drive. In addition, the concentration of harmful substances (CO, HC, NOX, soot) in automobile exhaust increases, resulting in increased environmental pollution due to the decrease of inflation coefficient and the relatively thick mixture. 2. engine combustion is not normal atmospheric temperature is high, the temperature of the hot gas mixture into the cylinder is also high, the engine temperature throughout the work cycle is high, and radiator cooling efficiency is low, the hot oil pump makes the engine overheated, the combustion chamber end Mixture to accept more calories, increased pre-flame reaction, which is prone to deflagration. In addition, hot oil pump overheating of the engine so that stored in the piston top, the combustion chamber wall, the top of the valve and the spark plug on the formation of hot carbon deposits, hot oil pump easily lead to combustible mixture of pre-ignition. This abnormal combustion, hot oil pump more exacerbated the phenomenon of engine overheating, the formation of a vicious cycle, heat pump cylinder block and cylinder head easy to produce thermal deformation or even cracks, the more common is to burn the cylinder liner, valve and valve seat. 3. Motor oil deterioration Engine oil in the hot oil, high pressure work, the deterioration of the oil oxidation stability, heat pump exacerbated the thermal decomposition, oxidation and polymerization process. The oil mixes with incompletely burned products, water vapor condensed by the hot oil pump, and dust entrained in the intake air, causing oil deterioration. In addition, as the oil temperature is high, the viscosity decreases, the oil thinning, deterioration of oil, oil pressure decreases, hot oil pump engine parts surface is not easy to form a lubricating film. At the same time, hot oil pump metal parts due to thermal oil thermal expansion, the smaller the gap between the normal cooperation with the parts. These are accelerated wear parts, seriously affecting the service life of the engine.
