Estimating the term…
The invention relates to an oil separator for de-oiling crankcase ventilation gases of an internal combustion engine wherein the oil separator (1) comprises at least one cyclone encompassing a gas inlet connected to the crankcase of the internal combustion engine, a gas outlet connected to the air suction passage of the internal combustion engine, and an oil outlet connected to the crankcase sump of the internal combustion engine wherein the gas outlet, as a submerged pipe projects through a lid into the cyclone interior with the lid closing the cyclone at the top. The novel oil separator has a gas duct section which is provided above the gas outlet on top of the lid with the gas duct section comprising a cross-section horizontally enlarged to at least double size, and an oil drain passage is guided from this section downwards to the oil outlet or the crankcase sump.
