METHOD OF ENHANCING FUEL-POWER EFFICIENCY OF INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: fuel combustion stroke is shifted by an angle with respect to the crank rotation. The volume of the combustion chamber is constant during fuel combustion due to keeping the piston in the top dead center during this time interval without stop of rotation of the crank. This asynchronization occurs during rotation of the crank by 30-40 deg from the top dead center. So, gas pressure and tangential component of load by which the connecting rod acts on the crank achieve maximum. The internal combustion engine has connecting rod composed of two parts interconnected via a telescopic insert with springs which keep the connecting rod parts in compression condition. Rollers are symmetrically mounted on the top part of the connecting rod on the its sides. Cams are mounted on the webs of the crank in the plane of rollers. The cams are in contact with the rollers when the piston is in the top dead center before the completing of the working stroke. EFFECT: enhanced efficiency 2 cl, 4 dwg
