Abstract: A storage device stores a first mapping that receives, as an input, first input variables including a previously estimated value for a fuel temperature variable, a pump variable on a state of a fuel pump, a first engine variable on a state of an engine, and an outside air temperature variable on an outside air temperature, and outputs the fuel temperature variable. Further, an execution device is configured to acquire the first input variables and estimate the fuel temperature variable by applying the acquired first input variables to the first mapping. Therefore, it is possible to estimate the fuel temperature variable by applying the first input variables to the first mapping even without providing a temperature sensor.

Abstract: A system is for a diesel engine for detecting malfunctioning of an injection timing control apparatus. The apparatus controls an injection timing of fuel, pressurized by a pump, to be injected from injection nozzles. An electronic control unit (ECU) computes a target injection timing based on the running condition. The ECU controls the injection timing to set the actual injection timing to the target injection timing. The ECU computes a difference between the actual injection timing and the target injection timing. The ECU determines whether the injection timing control apparatus is malfunctioning when the difference between the actual timing and the target timing is greater than a predetermined value. The determination by the ECU is altered in accordance with the running condition of the engine.

Abstract: The warming up control device according to the present invention determines precisely whether the temperature of the catalytic converter of the internal combustion engine has reached the activating temperature of the catalyst after the engine starts, The device estimates the heat amount transferred from the exhaust gas the catalytic converter based on the amount of the fuel supplied to the engine, and calculates the total heat amount transferred to the catalytic converter after the engine starts. The device determines that the temperature of the catalytic converter reaches the activating temperature of the catalyst when the calculated total heat amount reaches a predetermined value. Since the completion of the warming up of the catalytic converter is precisely determined, the warming up operation of the catalyst, such as the ignition timing retardation, can be terminated at a proper time, thus an unnecessary increase in fuel consumption and a deterioration in the engine performance can be avoided.

Abstract: The start up fuel control device according to the present invention controls the fuel supply amount to an engine during the cranking operation. After the cranking operation starts, the device measures the time lapsed since the cranking operation started. Further, the measured time is stored in a backup RAM which can preserve the content of its memory even if a main switch of the engine is turned off. Since the time lapsed from the beginning of the cranking operation (cranking time) can be considered as a parameter representing the amount of unburnt fuel remaining in the cylinder, the device performs the following operation based on the cranking time to prevent the air-fuel ratio of the air-fuel mixture in the cylinders becomes too low (rich) for firing to occur. When the cranking time exceeds a predetermined period, the device starts a scavenging operation in which the fuel supplied to the engine is reduced in order to expel the fuel remaining in the cylinders by the cranking operation.
