Abstract
Apparatuses, systems and methods for utilizing crankcase compression air to effect forced air induction (i.e. “boost”) into the combustion chamber of an internal combustion engine is provided. In some embodiments, the apparatuses are a supercharger apparatus that is attached to an existing engine. In other embodiments, the supercharger components are located within the structure of a novel engine itself. An embodiment of the apparatus includes a conduit that includes three inlets: 1) an inlet that is capable of being placed in fluidic communication with the crankcase chamber of an engine; 2) an inlet that is capable of being placed in fluidic communication with an intake to a combustion chamber of the engine; and 3) an inlet in fluidic communication with the atmosphere.
Claims23
A supercharger for an internal combustion engine, the supercharger comprising:
- a conduit, said conduit including:
- a first inlet that is in fluidic communication with a crankcase chamber of the engine;
- a second inlet that is in fluidic communication with an intake port to a combustion chamber of the engine;
- a third inlet that is in fluidic communication with an atmosphere;
- and
- a centrifuge section positioned at least partially within said crankcase chamber proximate to said first inlet, said centrifuge section defined by a spiral shaped portion including at least one oil return port and configured to utilize centrifugal force to remove lubricant, fuel, and/or contaminants from an airflow as said airflow travels from within the crankcase chamber to the intake port of the combustion chamber,
- wherein said first and second inlets are positioned at respective first and second ends of said conduit, and said third inlet is positioned along a length of said conduit, such that a fluid flowing from said first inlet to said second inlet flows through said centrifuge section and past said third inlet.
An internal combustion engine, the internal combustion engine comprising:
- an intake port to a combustion chamber, a piston, a crankcase chamber;
- and
- a supercharger comprising:
- a conduit, said conduit including:
- a first inlet that is in fluidic communication with the crankcase chamber;
- a second inlet that is in fluidic communication with the intake port to the combustion chamber;
- a third inlet that is in fluidic communication with an atmosphere;
- and
- a centrifuge section positioned at least partially within said crankcase chamber proximate to said first inlet, said centrifuge section defined by a spiral shaped portion including at least one oil return port and configured to utilize centrifugal force to remove lubricant, fuel, and/or contaminants from an airflow as said airflow travels from within the crankcase chamber to the intake port of the combustion chamber,
- wherein said first and second inlets are positioned at respective first and second ends of said conduit, and said third inlet is positioned along a length of said conduit, such that a fluid flowing from said first inlet to said second inlet flows through said centrifuge section and past said third inlet,
- wherein said spiral shaped portion of said centrifuge section defines a first cross-section that is constant along a length of said centrifuge section, wherein said second inlet defines a second cross-section, wherein said third inlet defines a third cross-section, and wherein said second cross-section is smaller in dimension than at least one of said first and said third cross-sections.
