Internal charge air feed from rocker cover integrated intake runners

An engine system comprising:

• a rocker cover;
• an intake port integrated into said rocker cover;
• an intake runner formed within said rocker cover and communicatively coupled to said intake port;
• a gas and oil separator fixed to said rocker cover, said separator having an upper separator plenum, a lower separator plenum, and a gas and oil diffuser fitted therebetween, said lower separator plenum having an oil outlet;
• an oil flow accelerator communicatively coupled to said gas and oil separator, said accelerator having an oil inlet in fluid communication with said oil outlet of said lower separator plenum, said accelerator further including an oil outlet, said accelerator being at least partially fitted within said lower separator plenum;
• and
• a high pressure path formed through said lower separator plenum between said intake runner and said oil accelerator, said high pressure path providing a passageway having an input end and an output end, said input end directly connected to and in fluid communication with said intake runner, said output end directly connected to and in fluid communication with said accelerator.

A system for separating crankcase oil and gases in an internal combustion engine comprising:

• a rocker cover having an intake runner formed therein, said intake runner having an input end and an output end;
• an air intake fluidly connected to said input end of said intake runner;
• a gas and oil separator including an upper separator plenum, a lower separator plenum, a wall dividing said separator plenums, and an oil and gas diffuser fitted in said wall to define an opening between said upper and lower separator plenums, said upper separator plenum including an oil and gas mixture inlet and said lower separator plenum including an air outlet and an oil outlet;
• an oil flow venturi having an inlet end and an outlet end, said inlet end of said oil flow venturi fluidly attached to said oil outlet of said lower separator plenum;
• a high pressure path providing a passageway having an input end and an output end, said input end of said passageway directly connected to and in fluid communication with said intake runner, said output end of said passageway directly connected to and in fluid communication with said oil flow venturi between said inlet end and said outlet end thereof.
