Problems solved by technology

However, even in the case where the above-mentioned EGR valve is actuated to be completely closed, the EGR gas introduced into the intake passage before closing the EGR valve flows into the combustion chamber with a certain delay with respect to the closing timing of the EGR valve, and thus the EGR gas becomes factors that cause internal combustion engine misfires

Embodiment 1

[0047] First, refer to Figure 1 to Figure 6 Example 1 of the present invention will be described.

[0048] [Description of system configuration] figure 1 is a schematic diagram showing the configuration of a system including the internal combustion engine according to Embodiment 1. figure 1 The system shown includes an internal combustion engine 10 . The internal combustion engine 10 is configured as an inline four-cylinder engine installed in a vehicle, and the combustion order of the cylinders is: first cylinder #1, third cylinder #3, fourth cylinder #4, and second cylinder #2, which Same as in normal engine. The intake passage 12 and the exhaust passage 14 communicate with each cylinder (combustion chamber) of the internal combustion engine 10 .

[0049] An air cleaner 16 is installed near the inlet of the intake passage 12 . A compressor 18 a of the turbocharger 18 is arranged downstream of the air filter 16 . The compressor 18 a is driven by the rotation of a turbi...

Embodiment 2

[0070] [Description of system configuration] Next, refer to Figure 7 and Figure 8 Example 2 of the present invention will be described.

[0071] The configuration of the system of Embodiment 2 is basically the same as that of Embodiment 1 described above. However, Embodiment 2 differs from the configuration of Embodiment 1 described above in that internal combustion engine 10 is an inline two-cylinder engine including a first cylinder #1 and a second cylinder #2.

[0072] Figure 7 It is a schematic diagram showing the inside of the intake manifold 22 of the second embodiment. Such as Figure 7 As shown, a guiding device 22c is provided at the bottom of the collective portion 22a. The guide 22c is provided from the vicinity of the outlet portion located on the right side of the intercooler 24 to the branch portion 22d between the first cylinder #1 and the second cylinder #2. Figure 8 is along Figure 7 Cross-sectional view of line A-A in. Such as Figure 8 As shown...

Embodiment 3

[0077] [Description of system configuration] Next, refer to Figure 9 and Figure 10 Embodiment 3 of the present invention will be described.

[0078] The configuration of the system of Embodiment 3 is basically the same as that of Embodiment 1 described above. However, Embodiment 3 differs from the configuration of Embodiment 1 described above in that internal combustion engine 10 is an inline six-cylinder engine including first cylinder #1 to sixth cylinder #6. Note that the combustion order of the internal combustion engine 10 is: the first cylinder #1, the fifth cylinder #5, the third cylinder #3, the sixth cylinder #6, the second cylinder #2, the fourth cylinder #4; or the first cylinder #1, fourth cylinder #4, second cylinder #2, fifth cylinder #5, third cylinder #3, sixth cylinder #6.

[0079] Figure 9 It is a schematic diagram showing the inside of the intake manifold 22 of the third embodiment. Such as Figure 9 As shown, only one guide 22c is provided at the b...

Abstract

When a deceleration request is issued while the engine load of the internal combustion engine (10) is in a predetermined high load region and the vehicle is decelerated in response to the deceleration request so that the engine load shifts from the high load region to the low load region, execution continues from the first The fuel supply to the injectors (36) of the cylinder (#1) and the fourth cylinder (#4) and cut off the fuel supply from the injectors (36) of the second cylinder (#2) and the third cylinder (#3) control. Condensed water generated in the intercooler (24) is caused to flow between two guides (22c) provided at the bottom of the collection portion (22a) of the intake manifold (22) to thereby flow into the second In the intake manifold (22b) of cylinder (#2) and third cylinder (#3).

Description

technical field [0001] The present invention relates to an internal combustion engine, and more particularly to an internal combustion engine equipped with an EGR device that recirculates a portion of exhaust gas into an intake passage. Background technique [0002] There is known an internal combustion engine which is equipped with an EGR device which has an EGR passage connecting the exhaust passage and the intake passage and passes a part of the exhaust gas flowing through the exhaust passage on the downstream side of the turbine as EGR gas through the The EGR passage recirculates to the intake passage on the upstream side of the compressor. Distinguishing between the EGR device of the above-mentioned type and the EGR device that recirculates a part of the exhaust gas flowing through the exhaust passage located on the upstream side of the turbine to the intake passage located on the downstream side of the compressor via the EGR passage, the EGR device of the above-mention...
