1. Detailed engine cooling system
The engine cooling system play in the automobile power system, an important role, the cooling system for temperature properly adjusted and controlled during engine operation, the engine of the components held in the normal operating temperature, in order to achieve the desired power output and good fuel economy, without the help of the cooling system, the engine will not work.
When the temperature of the combustion mixture into the cylinder up to 2000 degrees Celsius or more, when the engine piston, the cylinder, the cylinder head, valves and other components in contact with the high temperature combustible gas mixture strongly heated.
Effect of temperature on the action of the engine and cooling system
mentioned cooling system, we must first understand the effect of temperature on the engine. Car engine working cycle is carried out at a high temperature, the temperature at which the mixture into the combustion cylinder of up to 2,000 degrees Celsius. At this time, the engine piston, the cylinder, the cylinder head, valves and other components in contact with the high temperature combustible gas mixture strongly heated, if not effectively cool the engine at this time will deteriorate their mechanical strength, while causing the pneumatic cylinder coefficient decreased, resulting in abnormal combustion of the engine air-fuel ratio imbalance. The in-cylinder temperature is too high will make the gas mixture pre-ignition (advance combustion), resulting in serious damage to the engine knock phenomenon. Too high a temperature will make the lubricating oil burning and deterioration, the gap will become smaller in the cylinder at high temperatures, destruction of the protective film, resulting in decreased lubricity, can also cause severe adhesive wear, stuck
