Abstract: In the case of performing a main injection, and a sub-injection that injects a minute amount of fuel in a region (i) in Fig. 3, 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 the in-cylinder injection valve 28 are made uniform between the checking injection and the sub-injection. A fuel amount that is actually injected from the in-cylinder injection valve 28 in the specific cycle is calculated based on the air-fuel ratio of exhaust gas discharged from the engine 10 and an in-cylinder air amount, and is compared with a fuel amount that theoretically should be injected from the in-cylinder injection valve 28.

Abstract: A control system for an internal combustion engine includes a temperature sensor and an engine controller. The sensor measures the temperature of exhaust gas passing through an exhaust manifold of the engine during each cycle. The controller selectively operates the engine in a first state and a second state. In the first, normal state, a quantity of fuel based on an open loop fuel mass command value is injected into the engine each cycle. In the second state, the controller determines a temperature of the exhaust gas during a normal cycle, injects the quantity and additional fuel into the engine during a second cycle, determines the temperature of the exhaust gas during the second cycle, compares the temperatures, and adjusts the command value for fuel to be injected each cycle when operating the engine in the first state.

Abstract: Based on respective signals from the combustion pressure sensor and a crank angle sensor, heat generation amount data in which a heat generation amount and a crank angle are related to each other is generated, and an estimated heat generation amount is calculated based on a fuel amount in the combustion cycle. When a final value of a heat generation amount in the combustion cycle is smaller than the estimated heat generation amount, the combustion state parameter is calculated based on the heat generation amount data to a crank angle corresponding to the final value of the heat generation amount. When the final value of the heat generation amount is equal to or larger than the estimated heat generation amount, the combustion state parameter is calculated based on the heat generation amount data to a crank angle at which the heat generation amount reaches the estimated heat generation amount.
