Abstract
An internal combustion engine 10 includes a supercharger 64 and an air supply system 40 including dual intake ports, aspirated air intake port 55 and charged air intake port 75. A piston 18 moveable in an engine cylinder 12 varies the volume of a combustion chamber 17. An exhaust system 80 removes combustion gases 99 from cylinder 12. Aspirated air induction is ceased when the piston displacement reaches approximately 75%-93% of maximum piston displacement. Charged air induction begins as aspirated air induction ceases and continues until piston 18 compresses the inducted air.
Claims20
An internal combustion engine comprising:
- a cylinder including:
- a combustion chamber;
- a piston movable in said cylinder so as to vary the volume of said combustion chamber;
- an exhaust system:
- for removing combustion gases from said cylinder including:
- an exhaust port in said cylinder;
- and
- an air supply system for supplying combustion air to said cylinder comprising:
- a naturally aspirated air intake system for supplying non-charged air to said cylinder comprising:
- a naturally aspirated air intake port in said cylinder;
- a valve controlling passage of air through said naturally aspirated air intake port;
- and
- an aspirated air passage including:
- a first end positioned for receiving noncharged air;
- and
- a second end in communication with said aspirated air intake port;
- and
- a charged air intake system for supplying charged air to said cylinder comprising:
- a charged air intake port in said cylinder;
- a valve controlling passage of air through said charged air intake port;
- a supercharger powered by said engine for drawing in and charging air;
- and
- a charged air passage communicating charged air from said supercharger to said charged air intake port.
An internal combustion engine comprising:
- a cylinder including:
- a combustion chamber;
- a piston adapted for reciprocating in said cylinder so as to vary the volume of said combustion chamber;
- an exhaust system for removing combustion gases from said cylinder including:
- an exhaust port in said cylinder;
- and
- an air supply system for supplying combustion air to said cylinder comprising:
- a naturally aspirated air intake system for supplying non-charged air to said cylinder comprising:
- a naturally aspirated air intake port in said cylinder;
- a valve controlling passage of air through said naturally aspirated air intake port;
- aspirated air valve operating means for opening said aspirated air valve so as to fill said combustion chamber with noncharged air as said piston increases the volume of combustion chamber;
- and
- an aspirated air passage including:
- a first end positioned for receiving non-charged air;
- and
- a second end in communication with said aspirated air input port;
- and
- a charged air intake system for supplying charged air to said cylinder comprising:
- a charged air intake port in said cylinder;
- a valve controlling passage of air through said charged air intake port;
- a supercharger powered by said engine for drawing in and charging air;
- a charged air passage communicating charged air from said supercharger to said charged air intake port;
- and
- charged air valve operating means for opening said charged air valve so as to release charged air into said combustion chamber.
