Two-stroke multi-cylinder engine
This patent describes an internal combustion engine having a pair of cylinder bores disposed at an angle to each other, pistons reciprocating in the cylinder bores, a crankshaft supported for rotation about an axis relative to the cylinder bores, connecting rods for transferring reciprocation of the pistons into rotation of the crankshaft, the connection between the pistons and the connecting rods being such that a side thrust is exerted on the pistons for causing the pistons to tilt in the cylinder bores during the power strokes of the pistons, and exhaust ports opening into the cylinder bores at one side of a plane passing through the respective cylinder bore axis and parallel to the crankshaft rotational axis, the improvement comprising each of the exhaust ports opening through the same side of the respective plane with respect to the direction of rotation of the crankshaft.
