Abstract:
PROBLEM TO BE SOLVED: To properly suppress a torque level difference by carrying out post-injection at changing from a single turbo mode to a twin turbo mode. SOLUTION: A controller for an internal combustion engine is suitably applied to a system equipped with a first supercharger and a second supercharger. A post-injection control means carries out post-injection in response to control for carrying out changing in changing from a mode of operating the first supercharger to a mode of operating the first supercharger and the second supercharger. By this, exhaust temperature is raised (that is to say, exhaust energy is increased) by the post-injection, and a coefficient of expansion can be improved. Therefore, dropping of the number of revolutions of a turbine of the first supercharger at changing can be recovered, and dropping of a boost pressure can be suppressed. Consequently, the torque level difference at changing can be properly suppressed. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a technology for avoiding a bad effect in the case of opening a low-pressure exhaust side bypass valve in a multi-stage supercharging system for internal combustion engine. SOLUTION: This multi-stage supercharging system for internal combustion engine includes: a high-pressure turbocharger; a low-pressure turbocharger; a low-pressure exhaust side bypass passage bypassing a low-pressure turbine; and a low-pressure exhaust side bypass valve for controlling the exhaust quantity flowing in the low-pressure side bypass passage. In the case of requiring catalyst warm-up (S101-YES) and opening the low-pressure exhaust side bypass valve, when a predetermined condition relative to reduction of the number of revolution of a low-pressure compressor is satisfied (S102-NO), the low-pressure exhaust side bypass valve is closed (S104).

PROBLEM TO BE SOLVED: To provide a technique for selecting and executing abnormal processing suitable for an abnormality generated in a walking robot. SOLUTION: This robot walks by changing an angle of each leg joint of a pair of leg links. The walking robot is provided with a controller 63 for adjusting the angle of each leg joint based on gait pattern data, and an abnormality detection means 76 for detecting the abnormality generated in the walking robot and detecting whether or not the detected abnormality is generated at least one portion of a standing leg and an idle leg. The controller 63 continues an adjustment of the angle of each leg joint based on the gait pattern data when the abnormality detection means 76 detects the abnormality and the detected abnormality is generated at the portion which is neither the standing leg nor the idle leg, and executes the abnormal processing for locking each leg joint in a grounding state of each toe after grounding each toe by a prescribed number of times, while reducing operation speed of each leg joint.
