摘要： A small capacity pre-catalytic system (34) is disposed immediately downstream of an exhaust port (18), and a large capacity main catalytic system (35) is disposed immediately downstream of the pre-catalytic system (34). The pre-catalytic system (34) includes finely divided catalyst supports (48), and a third stage heat exchanger (H3) is disposed between these catalyst supports (48) so that a heat transfer tube (49) is bent in a zigzag manner. Fourth stage and fifth stage heat exchangers (H4, H5) are disposed on the upstream side, in the flow of the exhaust gas, of the pre-catalytic system (34), and first and second stage heat exchangers (H1, H2) are disposed on the downstream side, in the flow of the exhaust gas, of the main catalytic system (35). Water is made to flow through the first stage heat exchanger (H1) to the fifth heat exchanger (H5) in a direction opposite to that in which the exhaust gas flows, thereby exchanging heat with the exhaust gas. This allows the catalyst temperature to be actively controlled within the optimal temperature range without degrading the energy efficiency of the entire system.

摘要： Pistons (41) are slidably received in a plurality of cylinders (39) disposed radially in a rotor (31), and a plurality of vanes (42) cooperating with the pistons (41) are disposed radially in the rotor (31), so that a vane chamber (54) is defined between a pair of the adjacent vanes (42). The radial movements of each of the pistons (41) and each of the vanes (42) are substantially stopped, so that the volumes of each of the cylinders (39) and each of the vane chambers (54) are not changed, for a period from the end of an exhaust stroke at which a gas-phase working medium is discharged from the cylinder (39) and the vane chamber (54) to the start of an intake stroke at which the supplying of the gas-phase working medium is started. Thus, it is possible to prevent the generation of a water hammer phenomenon due to a liquid-phase working medium confined in the cylinder (39) and the vane chamber (54).

摘要： In a rotary fluid machine for converting the reciprocal movement of pistons and the rotational movement of a rotor from one into another by the engagement of rollers and annular grooves with each other, a value in a positive peak region of a pressure load of pistons received by the rollers engaged in the annular grooves and a value of a positive peak region of a centrifugal force load received by the rollers are set, so that they are substantially equal to each other, and phases of the two peak regions are deviated from each other. In addition, the phase negative peak region of a vane pushing-down load received by the rollers and the phase of the positive peak region of the pressure load of the pistons received by the rollers are established, so that they are overlapped at least partially on each other.

摘要： A heat exchange system is provided in which low temperature water from a supply pump (15) is split and supplied to an auxiliary evaporator (17) provided so as to cover an exhaust port (16) extending from a combustion chamber of an internal combustion chamber (E) and to a main evaporator (11) provided downstream of the exhaust port (16). The direction of water flowing through the auxiliary evaporator (17) is parallel to the direction of flow of exhaust gas, and as a result an upstream section of the exhaust port (16), which has a high temperature, can be cooled effectively with low temperature water, and the escape of heat from the upstream section of the exhaust port (16) can be suppressed. The direction of water flowing through the main evaporator (11) is opposite to the direction of flow of exhaust gas, thus ensuring that there is a temperature difference between the water and the exhaust gas along the whole length of the water passage of the main evaporator (11) and enabling the heat exchange efficiency to be improved.

摘要： First heat exchangers (H4, H3, H2) are disposed within an exhaust port (18), within a pre-catalytic device (34), and on the downstream of a main catalytic device (35); the exhaust port (18), the pre-catalytic device (34), and the main catalytic device (35) being provided in each exhaust passage (33) of a multicylinder internal combustion engine. These first heat exchangers (H4, H3, H2) are independently provided for each of the exhaust passages (33), and a second heat exchanger (H1) is disposed in a section where these exhaust passages (33) are combined. Since the first heat exchangers (H4, H3, H2) are disposed on the upstream side of the exhaust passage (33), high heat exchange efficiency can be obtained by high temperature exhaust gas, and, moreover, the occurrence of exhaust interference can be avoided, thereby preventing any decrease in the output of the internal combustion engine.

摘要： A heat exchange system is provided that includes an evaporator (11) that carries out heat exchange between exhaust gas discharged from an exhaust port (16B) and water, exhaust gas passages (87, 88) on the upstream side in the direction of flow of the exhaust gas being disposed on the radially inner side, an exhaust gas passage (89) on the downstream side being disposed on the radially outer side, and an oxygen concentration sensor cooling portion (92) for cooling a mounting section of an oxygen concentration sensor (91) facing the exhaust gas passage (87) on the most upstream side being positioned on the radially outer side of the exhaust gas passage (87). Water is supplied separately to a water passage (W3) of the evaporator (11) and a water passage (W4) of the oxygen concentration sensor cooling portion (92), and the water passage (W3) of the evaporator (11) is arranged so that the direction of flow of the water is opposite to the direction of flow of the exhaust gas. It is thereby possible to improve the waste heat recovery efficiency of the evaporator (11) that carries out heat exchange between the exhaust gas of an internal combustion engine and water and, in particular, to minimize the escape of heat via the oxygen concentration sensor (91) for detecting the condition of the exhaust gas.

摘要： An internal combustion engine is provided in which an exhaust port communicating with a combustion chamber formed in a cylinder head is formed from independent exhaust ports, which are positioned on the upstream side, and a grouped exhaust port, in which the plurality of independent exhaust ports are combined. Water supplied from a supply pump passes through a water passage of the grouped exhaust port and a water passage of the independent exhaust ports while cooling the exhaust port, and a valve seat and valve guide on the periphery of the exhaust port, which have high temperatures, thus heating the water itself and thereby recovering waste heat of the internal combustion engine. The heated water carries out heat exchange with exhaust gas in an evaporator provided in an exhaust passage and turns into high temperature, high pressure steam, which drives an expander of a Rankine cycle system. It is thereby possible to maximize the recovery of heat transferred from the exhaust port to the cylinder head of the internal combustion engine.
