Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2016217295
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To ventilate the inside of a crank case even when a negative pressure does not generate in an intake passage.SOLUTION: An internal combustion engine 100 includes an engine body 1, a supercharger 23a disposed in an intake passage, an intercooler 24 disposed at a downstream side with respect to the supercharger 23a, and a blow-by gas reduction device 90 for introducing a blow-by gas in a crank case 4 to the intake passage. The blow-by gas reduction device 90 includes a bypass passage 94 connecting a first position and a second position of the intake passage, an ejector 95 sucking a blow-by gas from a fluid suction port 95c when the air flows in the bypass passage 94 from the first position to the second position, and a blow-by gas passage 97 connecting the crank case 4 and the fluid suction port 95c of the ejector 95. The first position is located between the supercharger 23a and the intercooler 24, and the second position is located at a downstream side of the intercooler 24.SELECTED DRAWING: Figure 9
