Stroke piston IC engine - has eccentric thrust crank, with thrust axis of piston power transmission point at opposite to rotation direction by predetermined extent

摘要

In a two or four-stroke internal combustion engine, the thrust axis of the power transmission point of the piston is opposed from the crank centre point to the direction of rotation by a value the extent of which ranges from one tenth to twice the crank radius. During a complete rotation of the crank between the two dead centres of the thrust crank an unsymmetrical rotary angle, and consequently an unsymmetrical piston course results. Thus, these two components can be optimised with the length of the piston connecting rod. USE/ADVANTAGE - To improve the conversion of heat energy to kinetic energy in an internal combustion engine.
