    Abstract: Provided is an internal combustion engine including a sparkplug disposed in the vicinity of the center portion of an upper wall surface of a combustion chamber. Tumble flow generated during lean burn operation is controlled such that the tumble flow shape changes according to the engine rotation speed between a first tumble shape (usual tumble shape) in which the flow direction of a gas around the sparkplug at the time of ignition is direction from an intake valve side toward an exhaust valve side in a latter half of a compression stroke, and a second tumble shape (ω tumble shape) in which the flow direction of the gas is reversed in the latter half of the compression stroke from the direction from the intake valve side toward the exhaust valve side to the direction from the exhaust valve side toward the intake valve side.

    Abstract: A fuel injection device includes a fuel injection valve at a position corresponding to a portion between intake ports in an internal combustion engine. The fuel injection valve includes a body and a needle inside the body. The fuel injection valve is disposed closer to a piston of the internal combustion engine than the intake ports are to the piston. A single fuel injection passage for conducting gaseous fuel is present between a valve seat of the fuel injection valve and a combustion chamber of the internal combustion engine. The flow cross section of the gaseous fuel in the fuel injection passage is larger on a side closer to the piston of the internal combustion engine than on a side closer to an ignition plug of the internal combustion engine over a specified length in an extending direction of the fuel injection passage.

    Abstract: Where performing a main injection, and a sub-injection that injects a minute amount of fuel in a short region of driving time, a check is conducted to determine whether or not the minute amount of fuel is injected accurately. In a specific cycle at a time of cold starting when catalyst warm-up control is performed, the main injection is omitted and a checking injection corresponding to a sub-injection is performed. Injection conditions of an in-cylinder injection valve are made uniform between the checking injection and the sub-injection. A fuel amount that is actually injected from the in-cylinder injection valve in the specific cycle is calculated based on an air-fuel ratio of exhaust gas discharged from an engine and an in-cylinder air amount, and is compared with a fuel amount that theoretically should be injected from the in-cylinder injection valve.

    Abstract: An internal combustion engine includes an ignition plug and an electronic control unit. The electronic control unit is configured to: (i) execute a lean-burn operation in a first operation region, (ii) execute an operation in a second operation region at an air-fuel ratio lower than an air-fuel ratio during the lean-burn operation, and (iii) control a gas flow in a cylinder so that a ratio of a change in a gas flow speed around the ignition plug during ignition to a change in an engine rotation speed in a first engine rotation speed region within the first operation region is smaller than the ratio in a second engine rotation speed region within the second operation region.
