ABSTRACT:
An internal combustion engine has first and second cylinders (12, 14), the first cylinder (12) having a larger swept volume than the second cylinder (14) and the second cylinder being formed in the crown of the first cylinder. First and second pistons (16, 18) are reciprocable respectively in the first and second cylinders (12, 14), the second piston (18) being formed as a protrusion on the crown of the first piston (16). A combustion chamber (20) is formed in the second piston (18) with an air port (44) opening into the first cylinder (12) and a second port (40) opening into the second cylinder (14). A first inlet is provided (25) for supplying air or the like into the first cylinder (12) during an induction stroke of the first piston (16) together with a fuel inlet (36) for supplying fuel to said second cylinder (14). A passage extends between the first and second cylinder to enable transfer of air from said first cylinder (12) to said second cylinder (14) other than through said combustion chamber (20) over a preselected angle of movement of the pistons relative to the cylinders for assisting movement of gases from said second cylinder (14) into said combustion chamber (20). Additional control means for controlling the movement of air is also provided.
