ABSTRACT:
A multi-cylinder engine block for an engine operating on the two-stroke cycle and having two or more adjacent cylinder bores (10,11,12) with the axes of the bores parallel and in a common longitudinal plane. Each cylinder bore having an exhaust port (20), and an exhaust passage (21) extending from each exhaust port (20) to an external surface (22) of the block in a direction generally at right angles to said common longitudinal plane (25). Two transfer ports (27,28) being provided communicating with the same cylinder bore on either side of the exhaust port in the direction of said common longitudinal plane. Each transfer port communicating with a respective transfer passage. The transfer ports (27,28) not extending beyond the common longitudinal plane (25), and the transfer passages (26,23) adjacent the respective transfer ports (27,28) extending in a direction generally tangential to the cylinder bore. The transfer ports (27,28) and transfer passages (23,26) being configured and located so the axes of two adjacent cylinder bores are spaced apart not more than about 1.22 times the diameter of the cylinder bores.
