A derate selection electronically reduces the rated thrust of the engine to either one or more prespecified values or by a selectable percentage of the normal flat rated thrust. As this new thrust limit cannot be exceeded during the takeoff phase, critical speeds such as V mcg and V mca change from those associated with full rated thrust.DEF Dosing Valve Failure. The dosing valve is responsible for injecting DEF into the exhaust stream and, if it malfunctions, your engine will be forced into derate. This is because the ECU will not receive the correct information about the amount of DEF in the system. As a result, will not be able to properly regulate the engine's emissions.
