摘要： PURPOSE:To improve the response performance in the increase of supercharge pressure by suspending the operation of the second cylinder group with an engine is in an extremely low revolution and driving two superchargers and permitting the communication between two cylinder group sides of an intake manifold by a gate valve. CONSTITUTION:When an engine is operated in an extremely low revolution range, the second cylinder group B is put into repose, and only the first cylinder group A is operated. The first and second superchargers 23 and 24 are driven in this state, and a gate valve 26 is opened to permit the communication of the cylinder group A and B sides of an intake manifold 35. The air supplied into the cylinders 1-3 of the first cylinder group A is supercharged through the both superchargers 23 and 24, and the inhaled air pressure is speedily increased. When the number of revolutions of the engine increases and the supercharge pressure increases to a prescribed value, an electromagnetic clutch 32 is cut-off of repose the second supercharger 24, and the inside of the intake manifold 25 is closed by a gate valve 26.

摘要： PROBLEM TO BE SOLVED: To suppress the change of a driving force by adjusting the driving force to a desired value and by absorbing the change of engine torque, even if change occurs in the engine torque. SOLUTION: This motor generator control method is for a parallel hybrid vehicle provided with an engine that has a cylinder internal pressure sensor and a motor generator that assists power generation by an engine output or the engine output by battery electric power. Based on the detected opening of an accelerator, engine revolutions, and preset demanded torque map, driver-demanding torque is calculated (Steps S10, S11). Using the output value of the cylinder internal pressure sensor, the change of the cylinder internal pressure is detected (Step S12). Based on this detected cylinder internal pressure, the predicted amount of change of the engine torque or the predicted amount of change of the driving force is calculated (Steps S13, S14, S15). According to the predicted amount of change of the engine torque, the assist amount or the regeneration amount of the motor generator is feedback-controlled (Step S16). COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To simultaneously prevent the discharge of soot and NOx, and to prevent the occurrence of engine stall. SOLUTION: This internal combustion engine simultaneously prevents discharging soot and NOx by executing low-temperature combustion wherein an EGR gas amount supplied into a combustion chamber 5 is more than the EGR gas amount at a peak of generation amount of soot, and wherein soot is hardly generated in order to prevent the discharge of soot and NOx at the same time. When low temperature combustion is conducted and the occurrence of engine stall is expected, namely when hard braking is judged on the basis of output data from a brake switch 60, a crank angle sensor 52, vehicle speed sensor 61, and the like, the performance of low temperature combustion is prohibited or the air-fuel ratio is sifted to a lean side, consequently the occurrence of engine stall is prevented.

摘要： PROBLEM TO BE SOLVED: To surely suppress engine vibration at the time of idling by controlling an intake air rate so as to converge engine rotating speed to a target value, and controlling an inert gas rate to the target value so as to converge intake pipe negative pressure to the target value, in a device wherein inert gas is supplied into a combustion chamber. SOLUTION: When inert gas is supplied into a combustion chamber 5, a generating rate of soot is increased, and attains a peak value. After that, when inert gas rate is supplied, a condition becomes an operating condition in which the soot is hardly generated. In such constituted internal combustion engine 1, an intake air rate is controlled to a target value at the time of combustion when an inert gas rate much more than an inert gas rate having peaked soot generating rate is supplied into the combustion chamber, and at the time of an idling operation, and a rate of the inert gas supplied into the combustion chamber 5 is controlled to the target value. After a rate of the inert gas supplied into the combustion chamber 5 is controlled, a rate of fuel injected from a fuel injection valve into the combustion chamber 5 is controlled to the target value so as to surely suppress engine vibration.

摘要： PROBLEM TO BE SOLVED: To improve purifying performance of NOx by setting a condition in a combustion condition in which rates of inert gas supplied to a combustion chamber is differed from each other in a first operating region of a low load side and a second operating region of a high load side, and setting an air-fuel ratio of exhaust gas to a theoretical air-fuel ratio while the combustion condition is changed from the first combustion condition to the second combustion condition. SOLUTION: In an internal combustion engine 1 wherein NOx absorbent 25 is arranged in an exhaust passage, combustion is changed into first combustion in which a rate of inert gas supplied into a combustion chamber is much more than a rate of inert gas having peaked soot generating rate and soot is hardly generated, and second combustion in which a rate of inert gas supplied into the combustion chamber is few more than the rate of inert gas having peaked soot generating rate. First combustion is performed in an operating region of a low load side and second combustion is performed in an operating region of a high load side. While the combustion is changed from the first combustion into the second combustion, an air-fuel ratio of exhaust gas is set to a stoichiometric air-fuel ratio or a rich condition, and NOx absorbed to the NOx absorbent 25 is discharged and reduced.
