GENERAL INFORMATION

The cam-shaft is in a head of the block of cylinders and is put in action by a gear belt from a cranked shaft.

Gazoraspredeleniye phases


OZD
24 ° before VMT
ZZD
116 ° after NMT
OZW
110 ° before NMT
ZZW
18 ° after VMT
OZD and ZZD – respectively opening and closing of the inlet valve
OZW and ZZW – respectively opening and closing of the final valve

Phases of a gazoraspredeleniye are given when lifting valve in 1 mm and the fixed levers of all valves, except the lever of the valve which phases are measured.

Cam-shaft
