• Stable water temperature can make the metal parts of the engine expand evenly, and avoid the deformation and wear of the parts caused by excessive temperature change.
• Excessive engine temperature will accelerate the oxidation and deterioration of engine oil and reduce the lubricating performance of engine oil; If the temperature is too low, the viscosity of the engine oil will increase and the fluidity will become worse, which will also affect the lubrication effect. The water temperature control valve maintains the normal water temperature, which helps to maintain the good performance of engine oil and prolong the service life of engine oil, thus better protecting engine parts.
• When the driver steps on the accelerator pedal, the engine needs to respond quickly and output corresponding power. Appropriate water temperature can make the electronic control system and fuel injection system of the engine work quickly and accurately, and improve the response speed of the engine.
• The water temperature control valve can make the fuel fully burn by ensuring the good combustion state of the engine. At the same time, the appropriate water temperature is also helpful to control the temperature and pressure in the combustion chamber and reduce the generation of nitrogen oxides.
• When the engine is at a suitable temperature, all systems can work normally and the combustion process is stable, so that stable power can be output. If the water temperature is too high or too low, it will lead to problems such as engine power decline and poor acceleration. The water temperature control valve ensures that the water temperature is normal, so that the engine can always maintain good power and meet the power demand of the vehicle under different driving conditions."
