A+TWO-CYLINDER RECIPROCATING PISTON ENGINE WITH A PLANETARY MECHANISM AND CHAIN DRIVE

<p>The article proposes a novel design of a two-cylinder reciprocating piston engine with a planetary flexible mechanism and a composite transmission system. The mechanism consists of crank elements,<br>gears, planetary gears (satellites), sun gears, a composite connecting rod, and a belt or chain drive, enabling<br>variable speed characteristics. A mathematical model has been developed based on the equations of motion<br>formulated using the second-order Lagrange differential equation. Were solved using the Runge-Kutta method<br>allowing the main kinematic and dynamic parameters of the system to be determined. The main advantages of<br>the proposed device include increased efficiency, improved reliability, and adaptability to technological pro-<br>183<br>cesses requirements. The design can be applied in internal combustion engines, compressors, press machines,<br>and agricultural machinery.</p>
