Publication number: 20040007202Abstract: A direct cylinder injection-type spark ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed in the top surface of a piston, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relatively small thickness. When the fuel injected in nearly the shape of a fan from the fuel injection valve is considered by being divided into a plurality of fuel segments in a radial direction, a side wall of the cavity has a first fuel deflection passage 82a and a second fuel deflection passage 82b for so deflecting at least two of the plurality of fuel segments as to pass near the spark plug. The side wall of the cavity is at least partly provided with a return portion 83 that protrudes toward the inside of the cavity.Type: ApplicationFiled: July 10, 2003Publication date: January 15, 2004Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toyokazu Baika, Tatsuo Kobayashi, Fumiaki Hattori, Takashi Hashima, Hiroyuki Hokuto, Toshimi Kashiwagura, Mutsumi Kanda, Hiroya Tanaka, Souichi Matusita, Shizuo Abe, Nobuyuki Muramatsu

Patent number: 6651612Abstract: An in-cylinder injection type spark-ignition internal combustion engine includes a spark plug, a fuel injection valve, and a piston having a top face and a cavity formed in a first part of the top face. The cavity is located closer to the fuel injection valve with respect to a center of the piston so as to bring the injected fuel toward the spark plug. A space formed in the cylinder at a top dead center of a compression stroke of the piston includes a first space in which a center of the cavity is located, and a second space. The top face of the piston is designed so as to reduce a volumetric difference between the first space and the second space, thereby preventing generation of a strong air stream flowing between the first space and the second space at around the top dead center.Type: GrantFiled: August 7, 2002Date of Patent: November 25, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventor: Tatsuo Kobayashi

Patent number: 6263855Abstract: A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a fuel injector and a cavity formed on the top surface of the piston. The cavity has a bottom wall, a spark plug side wall and a fuel injector side wall. The fuel injector injects fuel toward the bottom wall of the cavity in stratified charge combustion. The fuel mainly proceeds toward the spark plug side wall of the cavity along the bottom wall, is deflected by the spark plug side wall and is led to the vicinity of the spark plug. In the engine, the fuel injector side wall of the cavity is provided with a deflecting portion. If a part of the injected fuel proceeds toward the fuel injector side wall along the bottom wall of the cavity, that part of the fuel is led to the vicinity of the spark plug by the deflecting portion.Type: GrantFiled: March 29, 2000Date of Patent: July 24, 2001Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tatsuo Kobayashi, Souichi Matushita, Toshimi Kashiwagura, Shizuo Abe, Fumiaki Hattori, Taketoshi Fujikawa, Yoshihiro Nomura
