    摘要： A storage device of a control system stores a trained neural network that is trained by using training data to which information as to whether there is an abnormality in an air flow meter is given as a true label. The trained neural network receives, as inputs, condition index values including the opening of a throttle valve and the engine speed, a load detected value calculated based on a detection signal of the air flow meter, a load estimated value estimated without using the detection signal of the air flow meter, and a change index value indicating the degree of change of the engine load. A CPU of the control system executes a diagnostic process to determine whether there is an abnormality in the air flow meter, using the neural network, which receives the condition index values, load detected value, load estimated value, and change index value as the inputs.

    摘要： When a state where a lowered amount of a detection value of high-pressure side fuel pressure with respect to target fuel pressure is at least equal to a specified lowering determination value at least continues for a specified lowering determination time, a pump high-temperature determination is set “ON”. In the case where the pump high-temperature determination is set “ON”, boost control for increasing pressure of fuel that is supplied from a feed pump to a high-pressure pump (a set value of feed pressure) from a low-pressure set value to a high-pressure set value is executed.

    摘要： The purpose of the present invention is to provide a rotation speed detection device which achieves improved detection accuracy regardless of a compressor and the operating state of the compressor, and enables the prevention of the breakage of a detection unit. A rotation speed detection device for a compressor, wherein a detection unit for detecting full blades and splitter blades that are blades approaching a compressor casing of the compressor in response to a change in the inductance of a magnetic field is provided. The detection unit is provided in an overlap region in which the full blades and the splitter blades that are all blades can be detected and the exposure pressure is in the range of a gauge pressure of one atmosphere or less.
