ことを特徴とする内燃機関。 In an internal combustion engine, two or more through-holes are formed that communicate from the upper deck of the cylinder head to the crankcase in order to allow lubricating oil accumulated on the upper deck of the cylinder head to fall into the crankcase. The two pit holes had an upper end protruding above the oil level on the top deck and opening near the upper fresh air outlet, and a lower end opening in the direction of rotation of the rotating body rotating within the crankcase. Fresh air introduction passage pipes are arranged concentrically, and within the at least one other pit hole,
Blow-by gas passage pipes are arranged concentrically, the upper ends of which protrude above the oil level on the upper deck and open toward the upper breather case passage, and the lower ends of which open into the crankcase. Internal combustion engine.
