- The underside of the piston acts like a cooling area for the piston crown. In this area the cooling medium is circulated and the heat transfer takes place at the underside of the piston crown.
- If the underside of the piston crown is provided with the fins, as the fins have better cooling effect with sufficiently thickened crown, we can have better cooling of the crown the thickened crown have more strength.
- At the same time the fin effect will be utilized for better cooling.
- Hence both, more strength and better cooling effect, is achieved by having a thicker crown and fins.
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
