摘要： To avoid the generation of a pumping loss, a communication passage is formed as a bypass passage between an exhaust port and a combustion chamber in an internal combustion engine. The communication passage is provided with a one-way valve as an exhaust gas return amount adjustment means. The one-way valve includes a spring member having a spring constant set to the value such that a valve body does not displace toward the combustion chamber under the pressure of the exhaust gas in the exhaust port. An opening degree of the one-way valve is autonomously adjusted depending on the amount of air introduced from an intake manifold when the pressure within the combustion chamber becomes negative in the intake stroke. Then inside of the combustion chamber is kept at substantially the atmospheric pressure with the exhaust gas returned to the combustion chamber via the communication passage and the aforementioned air.

摘要： PROBLEM TO BE SOLVED: To solve the problem of a hybrid engine wherein, if an engine brake is applied during deceleration, its pumping loss may decrease regenerative efficiency. SOLUTION: In the hybrid engine that outputs power by selectively connecting the output shaft of an electric motor with that of a multi-cylinder internal combustion engine, the internal combustion engine comprises a communication hole provided in a position higher than the position of a piston top face when a piston in each cylinder reaches top dead center; a connection conduit for connecting the cylinders together so that gas circulates via their respective communication holes; and a circulation control means for controlling the circulation of gas in the connection conduit. The circulation control means circulates the gas in each cylinder via the connection conduit if regenerative operation of the electric motor is carried out during deceleration; in the operating states of the electric motor other than the regenerative operation, the circulation control means stops circulation of the gas via the connection conduit.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for detecting abnormal combustion conditions by means of ionization signals for performing feedback control of a reciprocating engine provided with EGR(exhaust gas recirculation) control. SOLUTION: In the system, a succession of ionization signals for successive cycles of a running engine are received, and a plurality of related ionization signals are processed for signal stability. The ionization signals are checked so as to determine if an abnormal combustion such as a knock or a misfire has occurred or not. Variation in the ionization signals that change with respect to an engine parameter over a combustion event of the reciprocating engine is measured, and a floating bounded space is associated with the ionization signal. If the ionization signal is partly within the floating bounded space, an indication that the abnormal combustion conditions has been detected is given. COPYRIGHT: (C)2006,JPO&NCIPI
