1. General
The Wärtsilä Engine Control System (WECS−9520) is specially designed for
two-stroke engines with Common Rail technology. This includes all engine-related
control functions (paragraph 3) and cylinder-related control functions (paragraph 4).
The engine-related control functions are as follows:
D Fuel pressure control
D Servo oil pressure for exhaust valve drive
D Cylinder lubricating system.
The cylinder-related control functions are as follows:
D Volumetric injection control, which includes Variable Injection Timing (VIT)
D Exhaust valve control, which includes Variable Exhaust valve Opening (VEO) and
Variable Exhaust valve Closing (VEC)
D Starting valve control
D Crank angle sensor.
Data buses transmit signals between the external systems, the Propulsion Control
System (PCS) and the Alarm and Monitoring System (AMS) (paragraph 5). These
data buses are the interface between the operator and engine control.
