Not going to richen up a mixture by dropping the rpm. A diesel is an
excess air engine. The air intake is not normally restricted ( some are
va***e governed) and the fuel injected is not related to the amount of
air in the cylinder but rather in response to the required output power
up to the the max fuel setting
