ABSTRACT OF THE DISCLOSURE A manifold system for a two stroke cycle vertical shaft internal combustion engine A series of horizontal bores are perpendicular to the vertical shaft. A piston located in each bore establishes a combustion chamber and a fuel-air mixture supply chamber therein. A passage connects the supply chamber to the combustion chamber and a manifold system connects the supply chamber to a mixing chamber. Each mixing chamber is connected to an independent fuel supply and to a common air supply. A valve is located between the mixing chamber and the supply chamber to control the communication of a fuel-air mixture between the mixing chamber and the supply chamber. When the piston moves toward the combustion chamber a fuel-air mixture therein is compressed and at the top of the stroke ignited to produce combustion. As the piston moves toward the combustion chamber, the supply chamber expands and draws in a fuel-air mixture. When combustion occurs, the piston moves toward the supply chamber causing the valve to close and compress the fuel-air mixture now in the supply chamber. After the piston has travelled a predetermined distance, the combustion chamber is communicated to the surrounding environment and the passages opened to allow the fuel-air mixture therein to flow into the combustion chamber. At the bottom of the exhaust stroke, the piston again moves toward the combustion chamber to initiate the compression stroke in a cycle of operation. In order to assure that the fuel-air ratio of the mixture supplied to each supply chamber is substantially identical a dam is located between the mixing chamber and the common air supply. The dam intercepts and retains any fuel delivered to the mixing chamber hut not communicated into the supply chamber thereby preventing fuel from adjacent mixing chambers being intermingled during a compression stroke Thus, the fuel-air ratio for each piston remains substantially constant for each piston in this internal combustion engine.
