Abstract
Systems are provided for separating oil from blow-by gases in an internal combustion engine. In one example, a system comprises a camcover configured to be mounted on a cylinder head, and a baffle positioned between the camcover and the cylinder head. The baffle may include at least a first and a second baffle plate, the first baffle plate including a first through-hole on a first face of the first baffle plate, the second baffle plate including a second through-hole on a second face of the second baffle plate. Further, the first and second faces may be positioned opposite one another, and offset such that the first and second through-holes are not fully overlapping.
Claims19
A system with an internal combustion engine comprising:
- a camcover configured to be mounted on a cylinder head;
- a first overhead cam driven by a first camshaft;
- a second overhead cam driven by a second camshaft;
- and
- a baffle positioned between the camcover and the cylinder head, the baffle including at least a first and a second baffle plate, the first baffle plate including a first through-hole on a first face of the first baffle plate, the second baffle plate including a second through-hole on a second face of the second baffle plate, the first and second faces positioned opposite one another, and offset in a substantially horizontal direction extending laterally between and perpendicular to the first and second camshafts such that the first and second through-holes are not fully overlapping.
A system with an internal combustion engine comprising:
- a camcover configured to be mounted on a cylinder head substantially above at least a cylinder located at a first end of the engine;
- and
- a lower baffle plate assembly including a plurality of baffles affixed to a baseplate, the plurality of baffles positioned between the camcover and the cylinder head and substantially above the cylinder located at the first end of the engine, each of the plurality of baffles including at least a first and a second baffle plate, the first baffle plate including a plurality of substantially rectangular through-holes on a first face of the first baffle plate, the plurality of through-holes on the first face of the first baffle plate including a first substantially rectangular through-hole on the first face of the first baffle plate, the second baffle plate including a plurality of substantially rectangular through-holes on a second face of the second baffle plate, the plurality of through-holes on the second face of the second baffle plate including a second substantially rectangular through-hole on the second face of the second baffle plate, the first and second faces positioned opposite one another, and offset such that the first and second substantially rectangular through-holes are not fully overlapping.
A system with a gasoline-fueled turbo-charged two-bank direct injected engine comprising:
- an upper camcover configured to be mounted on a cylinder head of only one bank of the engine;
- and
- a lower baffle plate assembly including a plurality of baffles affixed to a base plate, the plurality of baffles positioned between the camcover and the cylinder head, each of the plurality of baffles including at least a first and a second baffle plate, the first baffle plate including a first through-hole on a first face of the first baffle plate, the second baffle plate including a second through-hole on a second face of the second baffle plate, the first and second faces positioned opposite one another, and offset such that the first and second through-holes are not fully overlapping.
