Control device and control internal combustion engine


Provided are a control device and a control method for an internal combustion engine, which enable a throttle-valve upstream pressure through simple calculation processing without being affected by a state of an opening degree of a wastegate valve (wgv). When a wastegate (wg) command value to a wgv driving section (212) for driving a wgv (33a) provided in a bypass passage (33) which bypasses a turbocharger (32) is to control supercharging to be weakened to the lowest level, the throttle-valve upstream pressure is estimated from an exhaust-gas amount.

Apparatus and selecting a cycle short pad


An apparatus for selecting a cycle short pad includes a saddle having pressure sensors and a processor which compares data from the pressure sensors to data stored in a database to suggest a preferred cycle short pad. The processor is connected to and, receives data generated by, the pressure sensors and produces a user pressure data set.

Method and diagnosing a fuel pressure sensor


A device executes a power limiting process when the number of pressure sensors determined to be normal in a second determination process made by a second processing unit is smaller than or equal to one. When only one pressure sensor is determined to be normal through the second determination process, and when that pressure sensor and a pressure sensor connected to only a first processing unit are determined to be normal in a first determination process made by the first processing unit, a process associated with fuel injection based on a detected value of the pressure sensor determined to be normal in the second determination process is executed, and a degree of limiting engine power through the power limiting process is reduced as compared with when both the pressure sensors are determined to be abnormal in the first determination process..
