4. Cylinder-related Control Functions
4.1 General
Each cylinder has an FCM − 20. A redundant system bus gives communication
between each FCM − 20.
The last and last but one FCM − 20 receive the crank angle signal from a redundant
SSI bus.
If an FCM
− 20 becomes defective, the related cylinder is cut out. The other FCM − 20
continue to operate.
4.2 Functions
The the cylinder-related control functions are as follows:
D Volumetric injection control (with VIT)
D Exhaust valve control (with VEO/VEC)
