Abstract
Abstract This application discloses a novel internal combustion engine incorporating the advantageous features of two cycle and four cycle engines in a single simplified engine. A stationary vertical crankshaft and a cylinder block disposed for rotation about the crankshaft are disclosed. Cylinder sleeves disposed in the rotatable block assembly include intake and exhaust ports which are substantially diametrically opposed with the valve action being controlled by the position of the piston within the cylinder sleeve in combination with nonrotative upper and lower intake and exhaust control plates. In one embodiment fuel as well as air for combustion and scavenging of the combustion chamber is provided by a blower system cooperating with a rotating blower ring attached to the block assembly. In another embodiment full injection is used. The engine includes a combustion chamber associated with each piston and also a secondary burning chamber which is opened at a predetermined point in the travel of each piston so that an additional charge of oxygen is applied to the combustion chamber after the main combustion has taken place. In another embodiment a tunable exhaust system is disclosed with portions of the exhaust being directed back to the cylinder intake for reburning. Construction details of the complete engine, the novel power transfer assembly for driving a vehicle, and a fuel injection system are disclosed.
