Hello,
I have a Atlas Copco QAS-150kv generator.
It has a power tech PVX 6.8_6 cylinder diesel John Deere Engine. After it comes up to operating temp, it sits there and flutters or makes a chuffing noise.
The engine has a variable turbo charger on it. the
Actuator arm flutters it will not keep a constant rpm.
The turbo actuator module has been changed. It still makes the same chuffing noise.
I have changed all of the temperature and pressure sensors on both the exhaust and intake manifold.
Also the EGR cooler the bypass valve the sensors for it have been changed and the intake manifold air valve has been changed too. When you put the engine under full load, it stops chuffing.
