- Power to Weight ratio is the ratio of horsepower produced to the weight of the engine itself.
- With high-speed or high-performance vessels, it is the most important criterion to use when comparing engines between two different makers since weight on these vessels is often critical, with vessel speed being the most important aspect of many military missions.
- Higher weight always equals higher displacement equals lower speed On commercial vessels, displacement is critical due to cost.
- Higher displacement requires more fuel to move the vessel.
- More fuel means higher cost of operation.
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
