Document Type and Number:
Japanese Patent JP5508632
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ventilate blow-by gas chambers 5, 7 while an exhaust turbo supercharger is operating, in an object comprising an internal combustion engine 1 in which a first blow-by gas chamber by a crank chamber 5 and a second blow-by gas chamber by a valve gear mechanism chamber 7 are communicated each other, and the exhaust turbo supercharger 14 having an exhaust turbine 15 and a blower compressor 16.SOLUTION: To a pressure transmission passage 27 for super charging pressure to an exhaust bypass valve 26 with respect to the exhaust turbine, a supercharging pressure control passage 32 provided with a pressure control valve 31 is connected. One end of the super charging pressure control passage 32 is connected to one blow-by gas chamber of both blow-by gas chambers 5, 7, and meanwhile the blow-by gas passage 30 from the other blow-by gas chamber of both blow-by gas chambers 5, 7 is connected to a site on an upstream side than the throttle valve 24, in the intake passage 22 from the blower compressor 16 to the intake manifold 9.
