2.5.2.1. Sensor of provision of a cam-shaft (SMR)

Fig. 2.228. Form of a wave of an output signal of the sensor of provision of a cam-shaft: 1 – sensor of provision of a cam-shaft; 2 – cam-shaft of inlet valves; 3 – angle of rotation of a cam-shaft 30 °; 4 – angle of rotation of a bent shaft; 5 – output signal of the sensor of provision of a cam-shaft; 6 – LF and L8 engines; 7 – L3 engine


For identification of the cylinder the sensor of provision of a cam-shaft finds a cam-shaft angle of rotation through 30 degrees after the top dead point of the piston of the first cylinder. The form of a wave of an output signal of the sensor of provision of a cam-shaft is shown in the figure 2.228.
