Short Description of the Engine
1. General
General data about the engine are given as follows:
D The X engine is a single acting, two-stroke diesel engine of crosshead design
with exhaust gas turbocharging and uniflow scavenging.
D The engine is reversible and is directly connected to the propeller.
D The X concept is based on the WinGD Common Rail, with full electronic control
of the fuel injection system and the exhaust valve operation.
D The engine control can have different remote controls, which are related to our
specifications, from recommended manufacturers.
D If the remote control has a failure, the engine can be controlled with the
emergency control from the local control panel.
D Tie rods hold the bedplate, columns and cylinder block together.
D A partition isolates the crankcase from the cylinder block. This partition includes
the piston rod glands for the piston rods.
D The thrust bearing and turning gear are installed on the driving end of the engine.
D The engine control system (ECS) controls the exhaust valve operation, electronic
fuel injection and cylinder lubricating system.
D The lubrication oil, coolant water, fuel supply, booster pumps and air
compressors are parts of the engine room installation (ancillary systems).
2. Systems
General data about the systems are given as follows:
D The servo oil system opens the exhaust valves hydraulically. The exhaust valves
are closed pneumatically.
D Servo oil pumps in the supply unit, supply bearing oil at the necessary pressure
through two high pressure (HP) oil pipes to the servo oil rail.
D Bearing oil cools the pistons.
D The fuel pumps in the supply unit, supply high pressure fuel through the HP fuel
pipes to the fuel rail. The fuel rail supplies high pressure fuel to all the
injection valves.
D Fresh water cools the cylinder liners and cylinder covers.
D A single-stage fresh water (closed−circuit) cooler keeps the scavenge air cool.
D The ECS controls the engine start sequence. Compressed air flows through the
starting valve into the cylinders to start the engine.
