Publication number: 20160290273Abstract: Embodiments of the present invention prevent the occurrence of rapid or intense self-ignition of fuel in an internal combustion engine that performs diesel combustion using a fuel having a relatively high self-ignition temperature.

Thereafter, main injection by an in-cylinder injection valve is performed before the top dead center of the compression stroke. In consequence, combustion of the fuel injected by the main injection is started by flame generated by the pre-combustion, and self-ignition and diffusion combustion of fuel occurs subsequently. Moreover, in at least a part of the operation range of the internal combustion engine, middle injection is performed at a time after the spark ignition of the pre-injected fuel and before the main injection. The fuel injected by the middle injection is burned by propagation of flame.Type: ApplicationFiled: April 1, 2016Publication date: October 6, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yuta OCHI

Publication number: 20160290307Abstract: A controller for an internal combustion engine includes a crank angle detector and an ECU. The ECU is configured to: (a) calculate a mass fraction burned; (b) acquire the crank angle, which is detected by the crank angle detector when the mass fraction burned reaches a predetermined mass fraction burned, as a specified crank angle; and (c) control at least one of an amount of fuel injected, an amount of intake air, or ignition energy on the basis of a first difference. The first difference is a difference between a first parameter and a second parameter. The first parameter is a crank angle period from an ignition time to the specified crank angle or a correlation value of the crank angle period. The second parameter is a target value of the crank angle period or a target value of the correlation value.Type: ApplicationFiled: November 10, 2014Publication date: October 6, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigeyuki URANO, Masakatsu NAGAI, Yoshihiro SAKAYANAGI
