Abstract: A supercharging system 1 is changed over between a single stage supercharging mode in which an internal combustion engine 2 is supercharged only by a single turbo charger 3, and a two stage supercharging mode in which the internal combustion engine 2 is supercharged both by the turbo charger 3 and also by an electric supercharger 4. And the threshold values for a parameter that is used for operating a bypass valve 13 are different for the case in which closing operation of the bypass valve 13 is performed in order to change over from the single stage supercharging mode to the two stage supercharging mode, and for the case in which opening operation of the bypass valve 13 is performed in order to change over from the two stage supercharging mode to the single stage supercharging mode.

Abstract: An internal combustion engine is provided with a variable mechanism capable of adjusting the amount of intake air introduced into each cylinder by controlling the operation angle of intake valves. In a low-load region, the intake valve operation angle is minimized, and the amount of intake air is controlled on the basis of the degree of throttle opening. In the low-load region, the operation angle of each valve is set so that there is no period during which both an intake valve and an exhaust valve are open. In a high-load region where the intake pipe pressure becomes equal to the atmospheric pressure, the amount of intake air is controlled on the basis of the operation angle. During this process, the degree of throttle opening is controlled so that the intake pipe pressure can be kept at the atmospheric pressure before and after the intake amount control based on the operation angle is performed.

Abstract: A device for controlling an internal combustion engine with a variable valve timing system is provided. While the piston descends just after the combustion in the cylinder, the intake valve is opened by the variable valve system for the intake valve such that the intake air is supplied into the cylinder from the engine intake system.

Abstract: When an internal combustion engine including an electromagnetic valve drive mechanism driving a plurality of valves is to be stopped, application of current to at least one magnet for one valve or valve group is stopped at a different timing from another valve or valve group.

Abstract: An apparatus is provided which includes an internal combustion engine of a lean-burn type, an NOx catalyst disposed in an exhaust passage of the engine so as to remove nitrogen oxides contained in exhaust gas emitted from the engine, and a variable valve control system capable of changing at least one of the opening and closing timing and a lift of the intake valve and/or the exhaust valve for each cylinder of the engine. The variable valve control system is controlled so that the exhaust gas to which the NOx catalyst is exposed is controlled so as to be suitable for removing a selected gaseous component from the NOx catalyst when the selected gaseous component should be removed. A method of purifying an exhaust gas emitted from the above engine is also provided.

Abstract: A switching power supply comprises a transformer 3, a switching circuit 1, an output rectifier circuit, an output smoothing circuit, and a snubber circuit. A snubber capacitor 17 has one terminal connected to the one terminal of a snubber diode 19. The other end of the snubber capacitor is led to an output winding 4 of the transformer, while the other terminal of the snubber diode is led to the other of the electrode of an output rectifier diode 7. A snubber inductor 23 has one end connected to the connecting point of the snubber capacitor and the snubber diode, and the other end is. connected to the input side of the output smoothing circuit. The polarity of the diode is arranged to establish a charging loop circulating through the snubber diode, the snubber capacitor and the output winding of the transformer, so as to provide a reduced loss, in a cycle in which the voltage appearing at the output winding of the transformer is the reverse direction to the output rectifier diode.
