FCT
Flex Cam Technology
Building upon the Emission Reduction
System integration concept, FCT achieves
synergy between flexible fuel systems
and advanced air systems with maximum
utilization of the current engine design.
While maintaining high fuel injection
pressure over the whole operating range,
fuel injection and inlet valve timing are
load controlled and influenced by a lever
shaft which affects injection timing/
pressure and inlet valve events. Valve
timing changes at part load to raise effective compression and enhance complete
combustion. In addition, shifting the relative position of the lever to the fuel cam
increases injection pressure, producing
a finer atomization of fuel in a load range
where it would otherwise be difficult to
control smoke.
