Apparatuses, systems and methods are disclosed including apparatus for a ventilation system for supplying air to a crankcase of an internal combustion engine. The apparatus can optionally include a housing, an air filter, a lid and a pressure relief valve. The housing can form a cavity and having an inlet and an outlet therein. The inlet communicates with the cavity and is offset from a centerline axis of the housing. The air filter can be received by the cavity. An outer circumference of the air filter can be oriented at an angle that is substantially tangent to the inlet. The lid can be attachable to and removable from the housing for selectively accessing the air filter. The pressure relief valve coupled to the housing and in fluid communication with the cavity.

Positive pressure air cleaning apparatus for a crankcase ventilation system

Air valves, such as wastegates, utilize a shaft that rotates within a bushing system. Conventional deposition processes limit the thickness of the wear material between the shaft and bushing system. Accordingly, embodiments disclosed herein utilize one or more coating sleeves that are press-fit onto the shaft. This enables a thicker layer of wear material to be applied to the shaft, thereby improving the longevity and durability of the air valve, while also simplifying the manufacturing process. Embodiments may also utilize one or more anti-rotation features, such as a dowel or axial protrusion, and/or may utilize snap ring(s) to prevent axial sliding of the coating sleeve(s).

An engine system optionally including: a crankcase of an engine having a blow-by gas passing therethrough; a liquid source containing a liquid; and an oil separating apparatus in fluid communication with the blow-by gas. The oil separating apparatus having a coalescing filter to separate oil from the blow-by gas. Separate from the blow-by gas and the coalescing filter, the oil separating apparatus is in fluid communication with the liquid source to receive the liquid. The liquid is passed through the oil separating apparatus in a heat exchange relationship with the blow-by gas to maintain a desired temperature range for the blow-by gas.
