The first effect of the water temperature sensor is through relatively simple changes in its internal resistance to be achieved by varying the current variation through the resistor to drive the change in water temperature sensor changes indirectly tell people of the engine operating temperature. The second category, there is no change in the water temperature sensor in terms of structure, but its role is to provide an engine control unit temperature change analog signals. It is supplied by the supply voltage 5V power supply control unit, VDO oil pressure sensor, the control unit returns the signal to a linear change signal of 1.3V-3.8V. The main role is to tell the temperature of the engine control unit now how much. Conversely it is a signal to the control unit and its importance. The main engine work differently under different operating temperatures. For example: 86 degrees below the normal temperature of the engine more than 10 percent of jet fuel, the purpose is to allow the engine to rapid heating to reduce cold engine wear. The temperature rose to 86 degrees and then let the engine a little less spray oil, a little slow to make the temperature of regeneration. So its role is very important. If he had had a problem, wholesale oil pressure sensor to the engine control unit provides the wrong signal, such as in a hot car engine provides a low signal to your car if it's more than a little spray oil, so it becomes a little oil La. Combustion noise: the structure of diesel fuel in the combustion process, vibration and noise, oil pressure sensor, combustion noise level is very high in the cylinder, but the engine structure in most parts of the higher steel, its natural frequency more in the high frequency region, because of the sound wave propagation frequency response does not match, because you can not successfully came in low frequency high peak cylinder pressure level, while the high frequency cylinder pressure level is relatively easy to spread.
