Abstract
A variable compression and asymmetrical stroke internal combustion engine includes a cylinder, a drive piston reciprocally disposed in the cylinder, an auxiliary piston reciprocally disposed in the cylinder, apparatus for reciprocating the auxiliary piston at twice the speed of the drive piston and in a manner wherein the relative reciprocation is asymmetrical, an intake port communicably connected to the cylinder, an exhaust port communicably connected to the cylinder, and an ignition device operably connected to the cylinder.
Claims7
A variable compression and asymmetrical stroke internal combustion engine, which includes:
- a cylinder;
- a drive piston reciprocally disposed in said cylinder,
