摘要： In an injector driving apparatus, a driving circuit supplies a current individually to each coil of multiple injectors, a current detection element detects the current flowing in a common current flow path, which is common to the coils, a current supply period guard part forcibly stops the current supplied from the driving circuit to the coil upon determination that a measured period reached a predetermined set period based on a detection result of the current detection element, and a diagnosis part operates in a period of no fuel injection to check whether the current supply period guard part normally stops the current supplied to the coil, by continuously supplying the current to the coil for only a short period, which disables the injector to open a valve, and sequentially switches over the coils.

摘要： The fuel pressure sensor abnormality diagnosis apparatus diagnoses that a fuel pressure sensor is abnormal in the case where, because a state where a detected value of the fuel pressure sensor is less than a target value occurs, a fuel discharge amount of a fuel pump is increased, and as a result, the fuel discharge amount reaches its maximum amount, and even if a predetermined period has elapsed since the fuel discharge amount reaches its maximum amount, the detected value is less than the target value.

摘要： A failure diagnosis apparatus for a fuel level sensor that detects a fuel remaining quantity within a fuel tank including at least a first tank and a second tank includes: a range deter mining unit for determining a range of a fuel remaining quantity on the basis of an output value of the fuel level sensor, the range being classified into a plurality of ranges in accordance with an output characteristic of the fuel level sensor; and a range failure diagnosis unit for carrying out failure diagnosis of the fuel level sensor for each range by comparing a fuel consumption quantity since the ranges are changed with a failure determining threshold value individually set up for each range. In a dead zone range in which a change in the output value of the fuel level sensor becomes small when a fuel consumer is switched from the first tank to the second tank, the range failure diagnosis unit sets the failure determining threshold value to a value corresponding to a fuel consumption quantity required to pass through the dead zone range.

摘要： A method of detecting a stuck plate valve of a gas engine. An accelerometer is mounted on or near the valve, such that the valve is operable to detect the closing and/or opening of the valve. A detection unit stores values representing the output of the accelerometer when the valve is operating normally. During operation of the engine, the detection unit receives current output from the accelerometer, and compares the current output with the stored values to determine whether the valve is operating normally.

摘要： In a method for operating a fuel injection device of a motor vehicle, fuel is conveyed under high pressure into a high-pressure reservoir, the pressure of which is controlled with the aid of a pressure regulation and from which fuel is taken for injection via at least one fuel injection valve under the control of a control device. A control pressure deviation of the pressure in the high-pressure reservoir is detected and the existence of a balance disturbance between quantity of fuel supplied to the high-pressure reservoir and quantity of fuel taken from the high-pressure reservoir is deduced from the control pressure deviation. If a balance disturbance exists, operational influencing of the fuel injection device counteracting the balance disturbance is produced and/or a corresponding report is generated.

摘要： A method and a device for identifying errors in emission-relevant control devices of a vehicle, such as the injection of fuel into a cylinder, allows error identification even if none of the sub-systems exceeds a predetermined threshold value. The method has the following steps: determining whether at least one parameter, which permits conclusions to be drawn about the emission behavior of the respective control device, lies in a desired range; if the parameter lies outside said desired range, an error value that correlates to an increase in emissions is stored; if the parameter is in the desired range, an error value of zero is stored; a total error value is formed from all error values of the control device and an error message is output if the total error value exceeds a predetermined threshold value.
