An internal combustion engine comprising:
- a cylinder block, said cylinder block comprising:
- an air inlet channel;
- an auxiliary cylinder;
- a transfer channel;
- a working cylinder;
- and
- an air exhaust channel;
- a shaft, said shaft configured to operate as both a crankshaft and a camshaft;
- wherein at least a portion of said shaft is rotatably mounted to said cylinder block;
- an air intake valve;
- an air intake cam, wherein rotation of said shaft is configured to rotate said air intake cam to actuate a rod of said air intake valve;
- wherein said air intake valve is configured to open for flow of air into said auxiliary cylinder;
- an auxiliary piston, said auxiliary piston configured to move in said auxiliary cylinder;
- a first crank;
- a first rod, wherein a first end of said first rod coupled to said auxiliary piston, and a second end of said first rod is coupled to said first crank, and wherein rotation of said shaft is configured to rotate said first crank to move said first rod to cause said auxiliary piston to move to compress air;
- a first bypass valve, said first bypass valve configured to be actuated by rotation of said shaft to open for flow of air out from said auxiliary cylinder into said transfer channel;
- a second bypass valve, said second bypass valve configured to be actuated by rotation of said shaft to open for flow of air from said transfer channel into said working cylinder;
- a working piston, said working piston configured to move in said working cylinder;
- a second crank;
- a second rod, wherein a first end of said second rod coupled to said working piston, and a second end of said second rod is coupled to said second crank;
- a fuel injector, said fuel injector configured to inject fuel into the compressed air within said working cylinder;
- means for igniting the fuel in said working cylinder to cause said working cylinder to move;
- wherein movement of said working cylinder causes said second rod to drive said second crank to cause rotation of said shaft;
- an exhaust cam;
- an exhaust valve, wherein rotation of said shaft is configured to rotate said exhaust cam to actuate a rod of said exhaust valve;
- wherein said exhaust valve is configured to open for removal of exhaust gasses out from said working cylinder;
- a first cover member, said first cover member configured to mount to said cylinder block to cover at least a portion each of:
- said intake valve, said auxiliary cylinder, and said first bypass valve, and being further configured to permit selective flow therebetween;
- a second cover member, said second cover configured to mount to said cylinder block to cover at least a portion of each of:
- said second bypass valve, said working cylinder, and said exhaust valve, and being further configured to permit selective flow therebetween;
- wherein said air intake valve is configured to open to permit flow of air into said auxiliary cylinder through a top end of said auxiliary cylinder;
- wherein said first bypass valve is configured to open for permit flow of air out from said auxiliary cylinder out of said top end of said auxiliary cylinder;
- wherein said second bypass valve is configured to open to permit flow of air from said transfer channel into a top end of said working cylinder;
- wherein said exhaust valve is configured to open for removal of exhaust gasses out from said to end of said working cylinder.
