摘要： A stratified-charge two-stroke internal combustion engine of the kind in which a rich mixture of fuel and air reaches each cylinder from an auxiliary transfer passage, and further air from a main transfer passage. The fuel-supply device for each cylinder is located in the auxiliary transfer passage well upstream of its entry into the cylinder so that substantial mixing of fuel and air takes place before entry. The rate of fuel supply is typically simply related to conditions in the auxiliary passage, and may be governed by a carburetor-type device located there or by a pressure-sensitive device located there and controlling a pump delivering through an injector. Multi-cylinder designs are described with a single fuel-supply device located in an auxiliary passage common to all the cylinders. Also the use of pistons of stepped form in which the face of one step takes the firing force by which that piston is driven, and the face of the other step exerts the pumping action by which combustion air is delivered to another cylinder by way of the auxiliary passage.

摘要： A stepped piston two cycle engine, of the type including at least one set of two cylinders each such cylinder having a working part of smaller diameter and a pumping part of larger diameter, at least the air for each charge required by the working part of each cylinder of the set being pumped along transfer passage means from the pumping part of the other cylinder of the set, has the working part of each cylinder provided with exhaust port means, main inlet ports, and auxiliary inlet port means. The main inlet ports are arranged symetrically about and spaced from a plane which contains a longitudinal axis of the cylinder and which passes through the center of the exhaust port means, and the auxiliary inlet port means is provided in the cylinder wall opposite to the exhaust port means. Main and auxiliary transfer passages are provided for the main and auxiliary inlet ports, the auxiliary inlet ports and auxiliary transfer passages lying wholly on one side of an axial plane which contains the axes of the two cylinders of the set, while the exhaust ports of both cylinders lie on the other side of this plane.Air only may be supplied to the working part of each cylinder through the main inlet ports, while fuel is injected into the air passing through the auxiliary transfer passages so that a mixture of fuel and air enters the working parts of the cylinders through the auxiliary inlet ports. By this means charge stratification in the working parts of the cylinders can be achieved.

摘要： A loop driven vehicle such as a motor cycle has a pivoted fork which supports the rear wheel mounted on the engine unit, and the engine unit mounted at its rear on the frame of the vehicle by a mounting which permits angular movement of the engine unit about a second axis parallel to the axis of rotation of the rear wheel, and fore and aft movement of the second axis. This movement of the engine unit is accommodated by one or more second mountings which permit the fore and aft and angular movement and may constrain the engine unit against movement in other directions. The mounting at the rear of the engine unit may comprise a pivoted member, or a flexible plate secured between the engine unit and frame.
