摘要： PROBLEM TO BE SOLVED: To cope with the high temperature abnormality of an EGR gas caused by a problem of an EGR cooler or the like. SOLUTION: An engine includes a cylinder injection injector for injecting directly fuel into a combustion chamber 2, and a port injection injector for injecting fuel into an intake port. The temperature THEGR of the EGR gas is detected on the outlet side of the EGR cooler (S1), to be compared with the first-third threshold values (S2-S4). An injection amount from the cylinder injection injector is increased to prevent knocking (S6), when the temperature of the EGR gas is elevated to exceed the first threshold value. An injection amount from the port injection injector is increased to prevent an intake system resin part from being fusion-damaged (S7), when the temperature of the EGR gas is further elevated to exceed the second threshold value. The EGR is stopped (S8), when the temperature of the EGR gas is further elevated to exceed the third threshold value. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent influence of gas introduction on an intake air swirl control valve in a structure wherein a gas introduction passage is formed in a separation part of two manifold arrangements and the intake air swirl control valve is arranged in a downstream side. SOLUTION: Tumble control valves (TCV) 38 and 40 are arranged on the downstream side from the gas introduction passage 30 and the upstream side from a position of an opening part 32b of a gas branch passage 32 in intake passages 4a-8a and 12a-16a. The TCVs 38 and 40 are nearer to combustion chambers of respective cylinders than the gas introduction passage 30, and thereby, swirls can be suitably generated in the combustion chambers. Further, the TCVs 38 and 40 are not exposed to EGR gas, and deposit adhesion and condensed water adhesion can be effectively prevented. The gas branch passage 32 is branched from the lowermost part of the gas introduction passage 30, and therefore, condensed water can be rapidly and surely delivered to the downstream side compared to the TCVs 38 and 40, and staying or freezing of water in the gas introduction passage 30 can be prevented during stop of the internal combustion engine.

摘要翻译：要解决的问题：为了防止气体引入对进气涡流控制阀的影响，其中在两个歧管装置的分离部分中形成有气体引入通道的结构，并且进气旋流控制阀布置在下游侧。解决方案：滚筒控制阀（TCV）38和40布置在气体导入通道30的下游侧，以及从进气通道4a-8a中气体分支通道32的开口部分32b的位置的上游侧和12a-16a。 TCV 38和40比气体导入通道30更靠近各个气缸的燃烧室，从而可以在燃烧室中适当地产生涡流。此外，TCV 38和40不暴露于EGR气体，并且可以有效地防止沉积粘附和冷凝水附着。气体分支通道32从气体导入通道30的最下部分支，因此与TCV 38和40相比，冷凝水可以快速且可靠地传送到下游侧，并且在气体中保持或冷冻水可以在内燃机停止期间防止引入通道30。版权所有（C）2010，JPO＆INPIT
