CONTROL SYSTEM AND METHOD FOR AN ELECTRONICALLY GOVERNED ENGINE OF A REFRIGERATION SYSTEM

There is disclosed a transport refrigeration system (10) comprising an electronically governed engine (60) that drives a refrigeration circuit (80) of the system (10). The engine control unit (65) is configured to operate the engine (60) in a droop mode of operation, in which the engine speed increases with decreasing engine loads from the refrigeration circuit (80), so as to maximise the cooling capacity of the system (10) at low engine load conditions.
