- Inadequate or failure of coolant supply and excessive deposit in cooling gallery.
- Continued overload operation
- Unbalanced cylinder load
- Incomplete combustion owing to loss of compression, faulty fuel timing, unstable fuel and insufficient charge air.
- High friction on liner owing to failure of lubrication, faulty rings conditions, long skirt touching the liner due Misalignment of piston and distorted liner
- Late ignition faulty fuel timing
- Excessive water content in fuel.
- Faulty rings conditions causing blow-by
- Long skirt touching the liner due Misalignment of piston and distorted liner
- Excessive deposit in cooling gallary
The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators
