- This arrangement has another advantage , when the valve is closing , the final steam blowing across the force setup high frictional resistance to closure of valve , this cause boiler pressure to fall below the blow off pressure before the valve closes.This is Blow down effect.
- This causes considerable wastage of steam , the shaped valve seat causes the valve lid to pulsate and this drilling action enables the valve to close properly and sharply with very little blow down effect
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
