|
ZZD
|
116 ° after НМТ
|
|
OZW
|
110 ° before НМТ
|
|
ZZW
|
18 ° after ВМТ
|
| OZD and ZZD – accordingly opening and closing of the inlet valve |
| OZW and ZZW – accordingly opening and closing of the final valve |
Phases timing are resulted at valve lifting on 1 mm and the fixed levers of all valves, except the lever of the valve which phases are measured.
