Patent number: 8186335Abstract: 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.Type: GrantFiled: September 25, 2008Date of Patent: May 29, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yoichi Ishibashi, Hideaki Morikawa

Patent number: 6095103Abstract: An exhaust passage for connecting to an exhaust port of a cylinder is provided. The exhaust passage includes a first path extending in a direction generally orthogonal to the central axis of the exhaust port. A second path connects the first path and the exhaust poil and a control valve is provided in the first path. The rotational axis of the exhaust control valve is generally parallel to the direction in which the first path extends. The surface area of an opening connecting the first path and the second path is variable as the exhaust control valve rotates, so as to carry out controlled combustion and exhaust timing. This makes it unnecessary to provide a hollow section for housing an exhaust control valve and bearing at a position close to the exhaust. It is also possible to reduce the size of a cylinder block and to realize smooth flow of exhaust gases by making the inner peripheral surface of the exhaust passage smooth.Type: GrantFiled: May 22, 1998Date of Patent: August 1, 2000Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yoichi Ishibashi, Masahiro Asai
