- To make small adjustments to each unit make uniform power generation
in every unit.
- Pmax by timing of fuel pump(vit or by shims to pump or cam floating
- Pcomp in ME engines by exh valve timing change.
- Pmax- Pcomp not more than 35 bar to avoid piston ring failure.
Pi adjusted by fuel index.
(But limits are The peak pressure difference can't be more than 3 to 5
for AE And max 10 for ME. Exhaust gas temp diff 40deg C.
Fuel rack should not be adjusted more than 10% Otherwise we have to
change the plunger and barrel)
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
