DIESEL ENGINE CONTROL DEVICE, DIESEL ENGINE, AND DIESEL ENGINE CONTROL METHOD

摘要

An ECU provided in a dual-fuel diesel engine performs governor control in which, when the load increases to a switching load ratio, the ECU reduces the rate of increase in the supply of oil fuel compared with that before the load increases to the switching load ratio and starts supplying gas fuel after a certain delay from timing at which the load reaches the switching load ratio. Furthermore, when the load decreases to the switching load ratio, the ECU reduces the supply of oil fuel to less than that before the load decreases to the switching load ratio and stops supplying gas fuel after a certain delay from the timing at which the load reaches the switching load ratio.
