Abstract: The oil mist separator includes a separator case, a gas inlet portion, a gas outlet portion, a separating component and a wall portion. The separator case is formed with a gas flow path. The gas inlet portion introduces the blow-by gas into the separator case on one side of the gas flow path. The gas outlet portion discharges the blow-by gas out of the separator case on the other side of the gas flow path. The separating component is disposed in the separator case and located between the gas inlet and outlet portions to separate the oil mist from the blow-by gas when the blow-by gas flows along the gas flow path. The wall portion is erected on the bottom wall in the separator case and faces the gas outlet portion at a position leaning toward the gas outlet portion between the separating component and the gas outlet portion.

Abstract: An intake apparatus of a V-type internal combustion engine including first cylinders arranged along a first direction in a first bank and second cylinders arranged along the first direction in a second bank, the intake apparatus includes a surge tank, first branch paths, second branch paths, and a protrusion. The surge tank is provided above the first and second banks. The surge tank includes a lower wall, an air inlet, first air outlets, and second air outlets. The first air outlets are arranged along the first direction in the lower wall. The second air outlets are arranged along the first direction in the lower wall. The first branch paths connect the first outlets to the first cylinders. The second branch paths connect the second outlets to the second cylinders. The protrusion is provided on the lower wall between a closest first air outlet and a closest second air outlet.
