Low speed diesel propulsion engine for ships
ME SERIES: 10200-31710 kW
H. Cegielski-Poznan
Characteristics:
-reduced fuel consumption,
- better cylinder compensation,
- better acceleration,
Detailed observation and diagnostics of ME series engines also revealed:
- easier service,
- longer intervals between overhauls,
- easier gain of mean indicated pressure (MIP).
The operators of engines also indicated lower fluctuations in engine revolutions during stormy weather compared to fluctuations in engines with fuel injection controlled by distribution shaft. The fuel savings of the order of 4% were indicated in comparison to engines without electronic control.
Detailed specification:
The essence of the engines from this group is based on automatic and hydraulic system of fuel injection activation and on the control of exhaust valves. The activating devices are electronically controlled here, through determined number of controlling systems forming "Engine Control System".
Fuel injection in the engines of ME series is improved by supporting pressure device (Buster), which mechanically is a simpler device compared to fuel pumps used in traditional engines of MC series. The fuel plunger in engines of ME series is driven by piston activated by electronically controlled, hydraulically dosing oil valve, which is also the source of fuel in this case. Also the exhaust valve is, in engines of ME series, hydraulically opened, and closed by pneumatic shockabsorber.
