Patent number: 8413318Abstract: A method for manufacturing an armature core is provided, in which a plurality of split cores, which are formed by laminating core pieces produced through punching by punching dies, are coupled together to form an annular shape as a whole, so as to manufacture one armature core. The method includes: preparing a plurality of sets of the split cores, each set having three split cores, so as to form one armature core; and arranging the three split cores in each set at intervals of 120° in the circumferential direction. The three split cores in each set are formed by core pieces that have been punched by the same part of the same punching die.Type: GrantFiled: March 9, 2011Date of Patent: April 9, 2013Assignee: Asmo Co., Ltd.Inventors: Shinji Ikeda, Kenji Yoshimura, Shingo Matsuoka

Publication number: 20130042843Abstract: To accurately specify an EGR rate from an output value of an in-cylinder pressure sensor, a specifying method of an EGR rate in an internal combustion engine of the present invention acquires an output value of an in-cylinder pressure sensor at an intake stroke to calculate comparison data related to an in-cylinder pressure at the intake stroke from the acquired sensor output value. An output value of the in-cylinder pressure sensor at an exhaust stroke of the same cycle is also acquired to calculate comparison data related to the in-cylinder pressure at the exhaust stroke from the acquired sensor output value. Two comparison data are compared to specify the EGR rate of an air-fuel mixture provided for combustion from a difference between the values.Type: ApplicationFiled: May 11, 2010Publication date: February 21, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takeshi Sano, Shinji Ikeda, Yusuke Suzuki, Soichiro Tanaka

Publication number: 20120004821Abstract: A torque estimating system for an internal combustion engine including a plurality of cylinders is provided that is capable of accurately estimating torque for each cylinder. A cylinder pressure of a CPS-mounted cylinder #1 is acquired (step 100). Measured indicated torque Te1 resulting from an explosion in the CPS-mounted cylinder #1 is calculated based on the cylinder pressure (step 102). A first angular acceleration d?1/dt and a second angular acceleration d?2/dt are calculated (steps 104 to 106). Estimated indicated torque Te2 resulting from an explosion in a CPS-less cylinder #2 is calculated using the measured indicated torque Te1 of the CPS-mounted cylinder #1 and a difference value between the second angular acceleration d?2/dt and the first angular acceleration d?1/dt (step 108).Type: ApplicationFiled: February 26, 2010Publication date: January 5, 2012Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takeshi Sano, Yusuke Suzuki, Shinji Ikeda
