ENGINE CONTROL DEVICE

WIPO Patent Application WO/2015/029314

A1

An engine (10) is provided with: first injection valves (21) for injecting a gaseous fuel; second injection valves (22) for injecting a liquid fuel knocking resistance of which is lower than that of the gaseous fuel; and a variable valve mechanism (28) that is capable of varying a valve open period of each intake valve (25) and advances intake valve opening timing in accordance with advancement of intake valve closing timing. When it is determined that a request has been made to increase the compression ratio of the engine (10), a control unit (80) advances the intake valve closing timing toward an intake bottom dead center. In addition, when the valve opening timing of the intake valve (25) overlaps with the valve opening timing of an exhaust valve (26) due to said advancement, the control unit (80) performs the supplying of fuel within one combustion cycle of the engine (10) by means of injection of the gaseous fuel by the first injection valve (21) and injection of the liquid fuel by the second injection valve (22).
