摘要： The center injection engine is an engine equipped with the direct injector and an ignition apparatus at center of a ceiling part of the combustion chamber. The positive tumble flow flows from the intake port side to the exhaust port side on the ceiling part side of the combustion chamber, and also flows from the exhaust port side to the intake port side on the piston top part side. The ECU calculates the injection timing of the direct injector based on the engine load. In the first injection control, the higher the engine load becomes, the more the end crank angle is retarded.

摘要： High pressure regions (31H to 35H) and low pressure regions (31L to 34L) are created based on the exhaust gas flow at curves in an EGR pipe (30), thereby enabling the exhaust gas pressure at inlets (21b to 26b) of gas introduction passages (21a to 26a) to be adjusted. Accordingly, regardless of the number of cylinders or whether the lengths of the flow paths of the EGR pipe (30) are the same, the exhaust pressure at the inlets (21b to 26b) of the gas introduction passages (21a to 26a) can be appropriately adjusted so any difference in pressure of exhaust gas introduced into branch pipes (21 to 26) can be reduced. In this way, the EGR rates of the cylinders can be made closer or the same such that stable combustion can be achieved, thus enabling stable engine operation to be maintained. The EGR pipe (30) is arranged weaving closely between the branch pipes (21 to 26) so space efficiency can be improved and a sufficient amount of exhaust gas can be introduced evenly into the cylinders.
摘要翻译：基于EGR管（30）中的曲线处的废气流量，产生高压区域（31H〜35H）和低压区域（31L〜34L），从而能够使气体入口（21b〜26b）的排气压力导入通路（21a〜26a）被调整。因此，无论气缸的数量还是EGR管30的流路长度是否相同，气体导入通路（21a〜26a）的入口（21b〜26b）的排气压力可以是适当地调节，从而可以减少引入分支管（21至26）的废气的压力差。以这种方式，可以使气缸的EGR率更接近或相同，使得可以实现稳定的燃烧，从而能够保持发动机的稳定运行。 EGR管（30）布置在分支管（21至26）之间，因此可以提高空间效率，并且可以将足够量的废气均匀地引入到气缸中。
