- The diesel engine fuel injection piping is subjected to very high pressure, in the range of about 1200bar. Also, there is sudden increase and decrease of pressure which causes the fatigue in the material.
- Taking into consideration these two things it is necessary that the material and the manufacturing process of the piping should be such that it should be able to withstand the high pressure and fatigue.
- It is also of prime importance, from the point of view of safety of the ship and fire hazard, that the fuel pipe should not get cracked under these high pressures. In order to achieve these requirements, it is necessary to use fuel pump pipes made up of seamless, solid drawn tubes.
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
