Exhaust valve control unit
The exhaust valve control units (VCU) control the servo oil to the exhaust valve of the related
cylinders. The exhaust valve control units are attached to the servo oil rail.
When the solenoid valve operates, servo oil is released to the slide rod. This releases servo oil to
the piston (003) and thus oil opens the exhaust valve.
