Abstract
A multi-cylinder internal combustion engine is disclosed including a crank shaft housing and a crank shaft connected to a plurality of pistons which reciprocate within the cylinders. The cylinder housing is vertically mounted to the crank shaft housing. A plurality of concentric sleeves are arranged within the cylinder housing and enclose a plurality of pistons and cylinders arranged in tandem. The concentric sleeves are connected to a selected number of cylinders and to the crank shaft for rotating the crank shaft responsive to reciprocal movement of the pistons and cylinders.
Claims3
A multicylinder internal combustion engine including a crank shaft located within a crank housing, the improvement comprising:
- (a) a cylinder housing mounted on the crank shaft housing and extending vertically upwardly therefrom;
- (b) a plurality of concentric sleeves arranged within said cylinder housing and enclosing a plurality of pistons and cylinders arranged vertically in tandem within said concentric sleeves;
- (c) said pistons and cylinders are arranged in axially spaced piston - cylinder pairs, each of said pairs being connected to one of said sleeves by connecting studs;
- (d) rod means connecting said concentric sleeves to the crank shaft for rotating the crank shaft responsive to reciprocal movement of said concentric sleeves;
