2.1.2.1. Cam-shaft of the drive of valves

Fig. 2.13. Cam-shaft of the drive of valves: 1 – VVT-i regulator; 2 – cam-shaft of the drive of inlet valves; 3 – synchronization rotor; 4 – cam-shaft of the drive of final valves; 5 – cam-shaft drive asterisk


The cam-shaft of the drive of inlet valves has a synchronization rotor which ensures functioning of the sensor of provision of a cam-shaft. Due to the use of the VVT-i system the oil channel on which under pressure the engine oil necessary for work of the VVT-i system moves is provided in a cam-shaft of the drive of inlet valves. The VVT-i regulator providing change of phases of gas distribution is installed on a forward part of a cam-shaft of the drive of inlet valves.
