2080132 9115663 PCTABS00007 A two stroke double acting oscillating piston quadratic internal combustion engine or machine comprising a plurality of double acting, rectangular faced, arc shaped oscillator pistons (1), symmetrically spaced apart, and secured to an oscillator flange (2), oscillating on a shaft (4), secured to a wall (5), of a crank case housing (6). The oscillator flange (2), embodies a gudgeon pin (7), which is coupled by a single connecting rod (8), to a crank shaft (10), (embodying a flywheel (11)); the 3 moving parts forming a Quadratic Mechanism so that rotation of the flywheel (11), produces oscillating motion of oscillator and vice versa. The oscillator pistons (1), are encompassed by inner and outer concentric cylinders (13 /A 14), which are secured to a stator flange (15), to form an annulus containing the oscillator pistons (1), and also stator pistons (17), (secured to the stator flange (15)), located between the oscillator pistons (1). Inlet ports and exhaust ports are embodied in the stator flange and transfer ports and transfer passage in the oscillator flange (2), for uniflow scavenge.
