The electric conduction line (52) includes a common section (56a) one end of which is connected to the drive circuit (52), and branch sections (56b) which are sections following the other end of the common section (56a) that the electric conduction line (56) branches off at and on which the two fuel injection valves (24R and 24L) for the same cylinder are respectively installed. The electric current value I flowing through the common section (56a) is detected. An electric resistance (58) that is inserted in the branch section (56b) for the fuel injection valve (24L), is provided. A fuel injection valve, at which an occurrence of abnormality concerning electric conduction is recognized, out of the two fuel injection valves (24R and 24L) for the same cylinder, is detected on the basis of the magnitude of the electric current value I.

    摘要： A fuel injection control system for an internal combustion engine in which a driving signal for a high pressure fuel pump is calculated by using proportional plus integral control based on a difference between a delivery pressure of the high pressure fuel pump and a target pressure thereof. A delivery pressure of a low pressure fuel pump is caused to decrease when an amount of change per unit time of an integral term shows a decreasing tendency or zero, whereas the delivery pressure of the low pressure fuel pump is caused to increase when the amount of change per unit time of the integral term shows an increasing tendency. In cases where an increase in the integral term resulting from a change in the target delivery pressure of the high pressure fuel pump has occurred, the increase in the delivery pressure of the low pressure fuel pump is prohibited.

    摘要： A terminal apparatus and a computer-readable storage medium capable of achieving reduction of power consumption by appropriately controlling lighting of a display unit are provided.A CPU lights or extinguishes a display unit after the end of an interrupt event in accordance with a lighting state (lighting, dim-lighting, being unlighted) of the display unit when the occurrence of the interrupt event is detected. It is therefore possible for the CPU to perform appropriate display control according to the lighting state when an interrupt event occurs.

    摘要： In a starting system of an internal combustion engine including a fuel injection valve that directly injects fuel into a corresponding cylinder and a spark plug that ignites an air-fuel mixture in the cylinder, injection of the fuel from the fuel injection valve and ignition performed by the spark plug are stopped when engine stop conditions are met. If the engine restart conditions are met during rotation of the engine after the engine stop conditions are met, the fuel is injected from the fuel injection valve into an expansion-stroke cylinder that is in the expansion stroke at the time when the engine restart conditions are met, and the mixture formed in the expansion-stroke cylinder is ignited by the spark plug.
