Camshaft position sensor, also known as the cylinder identification sensor, camshaft position sensors are generally expressed by CIS. Camshaft position sensor function is to collect the valve camshaft position signal, and input ECU, in order to identify the ECU compression TDC cylinder 1, thereby performing sequential fuel injection control, ignition timing control and knock control.

How to install vibration velocity sensors
Speed sensor vibration velocity sensor , the vibration velocity is typically used to measure the vibration of the bearing , but there are a few cases in the shaft for measuring vibrations. How to install vibration velocity sensors do ? In the measurement of vibration velocity , if sensor is installed incorrectly or is not securely installed , the measurement results will cause distortion due to vibration or damage caused by the speed sensor . So we have to consider a good choice for vibration velocity sensor is installed. When the speed sensor is used to measure shaft vibration when installed in the field are usually taken with the hand , sticky water plasticine magnetic disk fixed , bolted in several ways . In the temporary vibration measurement , in most cases, hand sensors way , this method measured flexible , easy to use , especially when the number of the lack of vibrationEngine Coolant Temperature Sensor interchangeability bad, has a special advantage ; And this the disadvantage is that the test measurement error is relatively large, and the intensity of work is relatively large . Current speed sensor when measuring the vibration velocity , usually people will use the Engine Coolant Temp Sensor fixing screws directly on the bearing , not only can reliably measure the bearing at the top of the vibration in three directions , but also can be measured in two directions perpendicular to the plane of vibration this method is the best way to install the measure . Also has a different installation methods , due to the installation of the various conditions to determine that we have a good effect on manually installing a useful little plasticine paste the speed sensor is also more convenient , you need to note that plasticine vibration Motor sensor can not be pasted into the vertical plane , and can only be fixed on a horizontal surface , as affected by temperature adhesive force , high temperature and the lower the adhesive strength will be significantly reduced, so it is not suitable for fixing the high temperature high pressure turbine rotor and reel measuring wheel speed sensor bearing ; winter cold start , the bearing temperature is too low and it is not used . There is a similar permanent magnet sucker fixed speed sensor mounting , etc., when we observe the installation follow the rules is to measure the needs , the need to make sense of your environment changes , so that the vibration velocity sensor mounted only purpose is to more has the effect of reducing unnecessary errors
