Patent number: 8146706Abstract: An air duct for vehicle air conditioning, includes a duct body defining a passage, and a passage dividing wall for dividing an interior of the duct body into a first passage and a second passage. In the air duct, the width of the duct body in an arrangement direction of the first and second passages in a bending section is larger than the width of the duct body in upstream-side and downstream side straight sections adjacent to the bending section, so as to increase a passage length difference (L1?L2) between the first passage and the second passage. Accordingly, the air duct has a structure capable of reducing the duct width while obtaining a desired passage length difference between the first passage and the second passage.Type: GrantFiled: August 6, 2007Date of Patent: April 3, 2012Assignee: Denso CorporationInventors: Naoki Katoh, Minoru Hashimoto, Masashi Watanabe, Tatsuya Toyama, Shigeyoshi Nagaya

Patent number: 6425789Abstract: An improved fuel delivery and injection system for a small watercraft engine reduces the heat effects within an enclosed engine compartment upon various components of the engine and upon the fuel within the fuel system. The fuel system integrates a fuel pump within a fuel tank at a location which minimizes the effects of watercraft leaning. The inlet of the fuel pump desirably corresponds, in the lateral direction, with a position of an inlet to the jet pump unit. In this position, the pump is less likely to draw air as the watercraft maneuvers. The fuel lines also are arranged within the engine to minimize the effect of engine heat produced by the exhaust system on the fuel delivery lines. The arrangement of the fuel pump and fuel delivery lines consequently improves the consistency of the fuel/air ratio within the fuel charge produced by the engine as less air and vapor delivered to the fuel injectors.Type: GrantFiled: December 8, 2000Date of Patent: July 30, 2002Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Ryoichi Nakase, Naoki Katoh, Shigeyuki Ozawa, Masayoshi Nanami

Publication number: 20020023627Abstract: An improved fuel delivery and injection system for a small watercraft engine reduces the heat effects within an enclosed engine compartment upon a fuel pump of and the fuel within a fuel injection system. The fuel delivery system includes a vapor separator and a high-pressure fuel pump. The fuel pump is at least partially located within the vapor separator. The fuel within the vapor separator cools the fuel pump. The vapor separator also is positioned between a pair of air ducts such that an air stream between the ducts cools the fuel within the vapor separator. This arrangement consequently improves the consistency of the air/fuel ratio in the fuel charges delivered to the engine cylinders, provides a compact structure between the fuel pump, and the vapor separator and improves the durability of the fuel pump.Type: ApplicationFiled: August 28, 2001Publication date: February 28, 2002Inventors: Ryoichi Nakase, Naoki Katoh, Shigeyuki Ozawa, Masayoshi Nanami
