Embodiment Construction

[0021] In the following figures, the same reference numerals will be used to refer to the same components. In the following description, various operating parameters and components are described for different constructed embodiments. These specific parameters and components are included as examples and not meant to be limiting.

[0022] In summary, the present invention relates to directing crankcase gases from the crankcase of an internal combustion engine and into the intake manifold for combustion through the use of an internal charge air feed from the intake device through And through the intake runners integrated into the rocker cover. Internal charge air enters an oil flow accelerator located in the oil separator and induces a high velocity oil flow on its intake side. The separated oil is returned to the crankcase and the separated air is returned to the intake manifold for combustion.

Abstract

A high pressure charge air feed arrangement for an internal combustion engine is provided. The arrangement includes an intake having a high pressure output, a rocker cover having an intake runner defining a high pressure charge flow path, and a gas and oil separator having a flow accelerator with input and output sides. The high pressure output of the intake is attached to one end of the path and the accelerator is attached to the other end. The path is connected between the input and output sides of the accelerator. The separator includes upper and lower plenums divided by a wall having an oil and gas diffuser. The input side is connected to the lower plenum and the output side is connected to a crankcase oil return line. The flow accelerator may be any type of fluid accelerator, including but not limited to a venturi pump and a jet pump.

Description

technical field [0001] The inventive concept of the present disclosure relates to engine emission control systems, and in particular to closed crankcase ventilation for internal combustion engines. More specifically, the inventive concepts of the present disclosure relate to internal combustion engines having an intake and a rocker cover with an associated closed crankcase ventilation oil separator assembly, wherein the closed crankcase ventilation oil separator assembly The assembly increases the oil flow rate by using an internal charge air feed from the air intake and through the intake runners integrated into the rocker cover. Background technique [0002] During the combustion phase of an air-fuel mixture within an internal combustion engine, exhaust gas is produced which exits the engine via an exhaust manifold during engine operation. However, not all of the gas leaves the engine at this point. Due to the pressure created during the combustion of the air-fuel mixtur...
