Patent number: 7191740Abstract: A cooling block forming a top wall of a combustion chamber of an internal combustion engine is formed by layering, from the outside to the inside, a casing, an upper layer block, a middle layer block, and a lower layer block. Labyrinth-shaped cooling water passages are formed on upper side faces of the three layers of blocks, and cooling water supplied from a cooling water supply passage flows from the cooling water passage on the side far from the combustion chamber to the cooling water passage on the side close to the combustion chamber, and is discharged from a cooling water discharge passage. Since the cooling water flows in a direction opposite to the direction of emission of heat of combustion from the combustion chamber, it is possible to ensure that there is sufficient difference in temperature between a cylinder head and the cooling water throughout the cooling water passages.Type: GrantFiled: October 23, 2002Date of Patent: March 20, 2007Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Atsushi Baba, Tsuneo Endoh, Masashi Shinohara

Patent number: 7069977Abstract: Heat transfer members (H4, H3, H2, H1) are sequentially 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 an exhaust passage (33) of an internal combustion engine. The heat transfer surface density (heat transfer area/volume) of the heat transfer members (H4) on the upstream side of the exhaust passage (33) is the lowest, and that of the heat transfer members (H1) on the downstream side is the highest. Thus, even though the temperature of the exhaust gas is higher on the upstream side of the exhaust passage (33) than it is on the downstream side of the exhaust passage (33), a uniform heat transfer performance across all of the heat exchangers (H4, H3, H2, H1) may be maintained.Type: GrantFiled: January 19, 2001Date of Patent: July 4, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masashi Shinohara, Haruhiko Komatsu, Seiji Nishimoto, Tsutomu Takahashi, Hideharu Izumi

Patent number: 7069884Abstract: 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.Type: GrantFiled: October 23, 2002Date of Patent: July 4, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Atsushi Baba, Tsuneo Endoh, Masashi Shinohara

Patent number: 7055315Abstract: 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.Type: GrantFiled: January 19, 2001Date of Patent: June 6, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masashi Shinohara, Tsuneo Endoh, Tsutomu Takahashi, Hideharu Izumi

Patent number: 7021059Abstract: 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.Type: GrantFiled: November 1, 2002Date of Patent: April 4, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masashi Shinohara, Tsuneo Endoh, Atsushi Baba
