摘要： PROBLEM TO BE SOLVED: To provide a controller of a premixed compression self-firing combustion engine capable of performing stable self-ignition combustion even if an intake air temperature changes.
SOLUTION: In this controller, when the intake air temperature is higher than a predetermined normal temperature range, an ECU 25 controls a variable valve timing mechanism 24 so that the closing timing of an exhaust valve 9 is adjusted to a retard-angle side to reduce the amount of a hot internal EGR gas and avoid excessive premature ignition. During medium and high loading. the ECU 25 reduces the amount of the internal EGR gas by increasing the retard-angle amount for the closing timing of the exhaust valve 9 more than during the low loading. During the medium loading in the medium and high rotation ranges, the rotational speed of an electric motor 16 is increased to increase supercharging pressure by a supercharger 17. The electric motor 16 of the supercharger 17 and an EGR control valve 22 are so controlled that, in the high loading during the high rotation range, the more the supercharging pressure is increased, the more the intake air temperature detected by a temperature sensor 26 is increased, and the amount of the external EGR gas is increased.

摘要： PROBLEM TO BE SOLVED: To provide an fuel injection device capable of sufficiently reducing combustion noise, HC, CO, smoke.SOLUTION: The fuel injection device has an injector for injecting fuel into a combustion chamber and an ECU for controlling the injector so as to inject fuel while dividing the same two times. In this case, the first time fuel injection is set so as to be carried out at a delayed angle side from the time when the preliminary mixing time directly after the first time fuel injection becomes minimum. The second time fuel injection is set so as to be carried out when a heat generation ratio waveform generated the first time fuel injection and ignition and the second time fuel injection and ignition is made a double mountain shape. Specifically, it is preferable that the second time fuel ignition is carried out after the heat generation ratio peak by a low temperature oxidation reaction generated by the first time fuel injection and is carried out and before the heat generation ratio peak by the high temperature oxidation reaction generated after the low temperature oxidation reaction by the first time fuel injection.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control apparatus which realizes premix compression ignition combustion that is low HC and low fuel consumption. SOLUTION: In a compression stroke, a fuel injection valve 2 injects a first portion of fuel immediately after -28° ATDC. Immediately after this injection, the fuel injection valve 2 injects a second portion of the fuel as close as possible to the first injection without overlapping. The amount of the fuel injected in the second injection is remainder obtained by subtracting the amount of the fuel injected in the first injection from the amount of the fuel required to obtain a required torque, and is more than the amount of the fuel injected in the first injection. Next, the fuel injection valve 2 injects a first portion of the fuel immediately after -18° ATDC. The amount of the fuel injected at this time is approximately double the amount of the fuel injected in the first injection at -28° ATDC timing and less than the amount of the fuel injected in the second injection.

摘要翻译：要解决的问题：提供一种燃料喷射控制装置，其实现低HC和低燃料消耗的预混压缩点火燃烧。解决方案：在压缩冲程中，燃料喷射阀2在-28°ATDC之后立即喷射燃料的第一部分。在该喷射之后，燃料喷射阀2立即将燃料的第二部分尽可能靠近第一次喷射而重叠。在第二次喷射中喷射的燃料的量是通过从获得所需扭矩所需的燃料量中减去在第一次喷射中喷射的燃料量而获得的余量，并且大于在第一次注射接下来，燃料喷射阀2在-18°ATDC之后立即喷射燃料的第一部分。此时喷射的燃料量大约是在-28°ATDC时刻喷射的燃料量的两倍，并且小于在第二次喷射中喷射的燃料量。版权所有（C）2011，JPO＆INPIT
