Abstract
An internal combustion engine-includes at least one cylinder crankcase, at least one cylinder head (2) including at least one valve cover (1), charge-cycle valves, a valve train-assembly, injectors (3), an injector cable harness, injection lines (4), a fuel rail (5) and a pre-separator for separating the oil aerosols present in the blow-by volume flow being situated in the cylinder head (2).
Claims20
An internal combustion engine comprising:
- a cylinder crankcase;
- a cylinder head;
- a valve cover;
- wherein the cylinder head includes charge-cycle valves, a valve train-assembly, an injector, an injector cable harness, injection lines, a fuel rail, and a web;
- wherein the valve cover includes a valve train space accommodating the valve train-assembly, a fuel rail space accommodating the fuel rail, and a deflector plate extending downward from a top of the valve cover,
- wherein the web and the deflector plate are configured in a manner of a maze and separate the valve train space from the fuel rail space, and
- wherein the deflector plate includes slots constituting unsealed passages from a valve train space into the fuel rail space allowing gas to transfer from the valve train space into the fuel rail space.

An internal combustion engine comprising:
- a cylinder crankcase;
- charge-cycle valves;
- a valve train-assembly;
- an injector;
- an injector cable harness;
- injection lines;
- a fuel rail;
- a cylinder head;
- a valve cover, a lower edge of the valve cover rests on top of and in contact with the cylinder head, the cylinder head and the valve cover defining a space receiving the charge-cycle valves, the valve train-assembly, the injector, the injector cable harness, the injection lines, and the fuel rail;
- and
- a deflector plate extending downward from a top of the valve cover, the deflector plate including vertically-extending slots extending upward from a bottom edge of the deflector plate, the vertically-extending slots being horizontally spaced apart from each other, the deflector plate dividing the space defined by the cylinder head and the valve cover into a valve train space including the valve train-assembly and a fuel rail space including the fuel rail,
- the injection lines passing horizontally through the vertically-extending slots, the vertically-extending slots configured for surrounding the injection lines in a manner allowing gas to transfer from the valve train space into the fuel rail space around the injection lines through the vertically-extending slots.
