Internal combustion engine with a high-pressure fuel pump

An internal combustion engine comprising:

• a shaft, said shaft configured to operate as both a crankshaft and a camshaft, said crankshaft comprising:
• a first crank, a second crank, an intake cam, an exhaust cam, and a bypass cam;
• a cylinder block, said cylinder block comprising:
• an opening configured to rotatably mount said shaft therein, and a pair of cylinders, with each cylinder of said pair of cylinders configured to interconnect with said opening for said crankshaft;
• said pair of cylinders comprising:
• a working cylinder, and an auxiliary cylinder;
• a working piston, said working piston configured to move in said working cylinder;
• a first rod, a first end of said first rod coupled to said working piston, and a second end of said first rod coupled to said first crank;
• an auxiliary piston, said auxiliary piston configured to move in said auxiliary cylinder;
• a second rod, a first end of said second rod coupled to said auxiliary piston, and a second end of said second rod coupled to said second crank;
• an intake valve, said intake valve configured to be actuated by contact with said intake cam;
• wherein said auxiliary cylinder is configured to receive air through said intake valve, and to compress the air;
• a bypass valve, said bypass valve configured to be actuated by contact with said bypass cam;
• wherein said bypass valve is configured to permit movement of the compressed air from the auxiliary cylinder into the working cylinder;
• a fuel injector, said fuel injector configured to inject fuel into said working cylinder;
• means for igniting the fuel in said working cylinder;
• an exhaust valve, said exhaust valve configured to be actuated by contact with said exhaust cam;
• wherein said exhaust valve is configured to open for removal of exhaust gasses from the working cylinder;
• and
• at least one cover.
