State the difference between ME and MC engine
The me series of enignes have no cam shaft. Instead ,to provide power for fuel injection and exhaust valve lifting, they utlise a hydraulic oil loop with injection and exhaust valve lifting, they utilise a hydraulic oil loop with fine filtered oil from the main engine lubricating system at about 200bar pressure. The advantages of the ME series of enignes come from the fact that the timing and intensity of the fuel oil injection and exhaust valve opening and closing is optimal and intensity of fuel oil injection and exhaust valve opening and closing is optimal at all steady and transient loads, thus giving lower part load fuel oil consumption, lower emissions and particularly smoother and better low load operation. The balance between cylinders will be easier to adjust smooth operation.
With improved combustion due to the electronic control of fuel injection.
