<P>PROBLEM TO BE SOLVED: To provide a control method of a fuel injection device that can improve fuel efficiency, exhaust gas, and combustion noise simultaneously by combining a multi injection and a rate shape injection, calculate an optimal fuel injection rate waveform, and jet fuel based on the optimal fuel injection rate waveform, and to provide an internal combustion engine, and a vehicle equipped with the same. <P>SOLUTION: A frequency and an injection amount of a pilot injection, a frequency and an injection amount of a rate shape injection, and a frequency and an injection amount of a post injection are set beforehand according to an operating condition of a diesel engine, a condition of fuel taken-in in a cylinder, and properties of the fuel used, and an optimal injection form 10 in which thermal efficiency is the highest, an exhaust gas component is minimal, and the combustion noise is minimal is calculated. The rate shape injections 12a and 12b in which the fuel injection rates are changed in two or more times of injection periods are performed based on the optimal injection form 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
