Abstract:

PROBLEM TO BE SOLVED: To provide an operation control device of an engine in which occurrence of an inconvenience with bubbles contained in a working fluid is prevented, by setting a target engine speed immediately after transfer to an idling condition to a level higher than the target speed complying with the idling condition.
SOLUTION: When an engine operation transfers to an idling condition at the time t2, the count Cnt of an idle counter begins counting. When the count Cnt reaches a set value Cnt1, the corrective amount Nad for an engine speed is added to a target speed complying with an idling condition. The corrective amount Nad decreases gradually with time elapsed after transfer into the idling condition. Because the fuel injection is executed so that the target speed becomes high, bubble production and/or expansion generated conventionally owing to a pressure sink in association with the transfer to the idling condition within an injector, etc., used in a fuel injection system.
