  • Inertia supercharging induction system for multi-cylinder internal combustion engine
    Patent number: 4838215
    Abstract: In order to minimize the supercharging effect from the cylinder to cylinder and to maximize the efficiency of the inertia supercharging effect over essentially the whole engine speed range, first and second elongate collectors which communicate with separate banks of cylinders are interconnected at essentially their mid points by a connection tube having a selected length and cross-sectional area. An engine speed responsive valve disposed in the tube or pipe selectively induces the situation wherein quasi separate induction systems are defined for each bank of cylinders or a single enlarged system is established.
    Type: Grant
    Filed: April 21, 1988
    Date of Patent: June 13, 1989
    Assignees: Nissan Motor Co., Ltd., Aichi Machine Industry Co., Ltd.
    Inventors: Makoto Yasuda, Syousabu Ura, Shuichi Nishimura, Isaya Matsuo, Masami Kato, Munehiro Sagata
