Fig. 2.187. Scheme of the mechanism of the drive of valves: 1 – inlet valves; 2 – cam-shaft of the drive of final valves; 3 – cam-shafts of the drive of inlet valves; 4 – cam-shaft of the drive of final valves; 5 – final valves


Valves open and closed directly by four cam-shafts (see fig. 2.187). Cam-shafts of the drive of final valves are put in action by a gear belt while cam-shafts of the drive of inlet valves are put in action by gear wheels on cam-shafts of the drive of final valves.
