摘要： This engine control device, for controlling an engine with a turbocharger, is provided with: a parameter acquisition unit configured to acquire a first parameter relating to the engine operation state; an insufficient air supply determination unit for determining whether or not an insufficiency in the air supply to the engine has occurred; an ignition timing map selection unit configured to select, from multiple ignition timing maps that indicate the relation between the first parameter and the engine ignition timing, an ignition timing map that corresponds to the determination result of the insufficient air supply determination unit; and an ignition timing determination unit configured to determine the engine ignition timing on the basis of the first parameter acquired by the parameter acquisition unit and the ignition timing map selected by the ignition timing map selection unit.

摘要： [Problem to be Solved] The combustion state is prevented from becoming unstable when an operating point fluctuates in a pre-chamber internal combustion engine.
[Solution] In an internal combustion engine including: a combustion chamber; a pre-chamber communicating with an upper center part of the combustion chamber via an injection hole; a fuel injection valve that injects fuel into an intake passage; first ignition means that faces an inside of the pre-chamber; and second ignition means that faces the combustion chamber, the control device is configured to perform: (i) a first combustion mode that performs ignition in the pre-chamber (50) by the first ignition means (5) in a steady state, (ii) transition to a second combustion mode that performs ignition in the combustion chamber (20) by the second ignition means (7) when a change in an operating point is determined in the steady state; (iii) transition to a third combustion mode that performs ignition by both of the first ignition means (5) and the second ignition means (7) when transition of the operating point is completed and it is determined that combustion of the second combustion mode is stable, and (iv) transition to the first combustion mode when it is determined that combustion of the third combustion mode is stable.

摘要： An engine system is provided, which includes a main combustion chamber, a subchamber, an injector that injects fuel into the main combustion chamber, a main spark plug that ignites a mixture gas inside the main combustion chamber, and a subspark plug that ignites the mixture gas inside the subchamber, an throttle valve, and a control device. In a first range, compression self-ignition combustion of the mixture gas inside the main combustion chamber is performed. In a second range, flame propagation combustion is performed while setting an air-fuel ratio of the mixture gas lower than that in the first range. Immediately after the transition from the first range to the second range, only the subignition is performed, or the subignition and the main ignition are performed while setting a timing of the main ignition to a timing same as or retarded from the subignition.
