摘要： Provided is a control device for an internal combustion engine, which improves acceleration performance while maintaining fuel performance in a non-supercharging operation range. A bypass passage (33) which bypasses a turbine (32c, 32d) of a supercharger is provided. In the bypass passage (33), a wastegate valve (33a) for adjusting a flow-path area of the bypass passage (33) by a wastegate actuator (33b) is provided. For an operation in the non-supercharging operation range, an opening degree of the wastegate valve (33a) is set to fully close the wastegate valve (33a) when a ratio of a pressure (Pb) of an intake manifold (22) and an atmospheric pressure (P1) is smaller than a threshold value.

摘要： Respective positive terminal electric potentials of exhaust gas sensors are sequentially selectively inputted to an analog input terminal of a multi-channel AD converter through a multiplexer. An offset voltage is applied to respective negative terminals of the exhaust gas sensors. This offset voltage is inputted to another input terminal of the multi-channel AD converter. A microprocessor detects a generating voltage of the exhaust gas sensors by the difference between a digital converting value of the positive terminal electric potential and a digital converting value of the negative terminal electric potential. The microprocessor also individually judges that each of the digital converting values is excessively small and excessively large. Thus, the microprocessor judges the existence of ground, sky short circuit and disconnection abnormalities of the negative terminal and the positive terminal.

摘要： An electronic throttle control unit for an engine can perform precise control by using a single inexpensive AD converter. The unit includes an electronic throttle that controls an engine, a throttle opening detection section that detects the throttle opening of the electronic throttle, and a control section that controls the throttle opening to a target value in accordance with an operating condition of the engine. The throttle opening detection section includes a throttle opening sensor that generates a sensor voltage corresponding to the throttle opening, an offset part that converts the sensor voltage into a plurality of voltages with offsets, a distribution circuit for distributing the voltages with offsets to a single path, an AD converter that AD converts the voltages distributed to the single path; and a distribution switching section that performs distribution switching control of the distribution part, wherein the distributed voltages are detected as a final throttle opening to be controlled.
