A multicylinder, two-stroke, radial, internal combustion engine employs a multi-blade positive-displacement pump for pressurizing a mixture of air/fuel/lubricant supplied to a plurality of cooperating cylinders. One of the pistons is connected to a master connecting rod which bears a plurality of crank pins respectively connected to the connecting rods of the other piston/cylinder assemblies of the multicylinder engine. The exhaust gases from the plurality of cooperating cylinders are collected in a common annular exhaust manifold and quietly emitted therefrom through a single exhaust port in a downward direction. A multibladed, positive-displacement pump draws an air/fuel/lubricant mixture from a carburetor through an annular volute which promotes fuel evaporation and supplies a pressurized intake flow to the cylinders via a single shared crankcase.
