DUQ1-005E-1 RTA / RT-flex Exhaust valve air spring, low air pressure problem

An increasing of an air consumption of the exhaust valve air spring will effect the exhaust valve timing to make engine performance worse. In case the air pressure is too low, the engine will be tripped during operating or can not start.

 

The reason of low pressure will be caused by :
1. Air leaking from air supply pipe, drain valve of lubricating oil or drain pipes.
2. Malfunction of pressure regulation valve 21A, 125HA, or 19HA (excluding RT-flex50 / B).
