Piston internal combustion engine with variable compression ratio and efficiency of the thermodynamic cycle

摘要

Reciprocating internal combustion engine with variable compression ratio and the efficiency of the thermodynamic cycle.; Using the - machine internal combustion engines.; The purpose of this utility model - development piston internal combustion engine, the kinematic scheme of providing:; changes in the degree of compression,; the change of the stroke,; absence of pressure on the piston cylinder wall of the forces; Gas pressure on the piston during rotation of the crankshaft,; minimizing the inertia forces,; more efficient thermodynamic cycle.; Summary of the utility model: Figure 1 by two mechanisms consisting of the crank, connecting rod, and two additional links, one of which is pivotally connected to the piston pin, the second to change the compression ratio, freely planted on the eccentric, the second of which is located on the housing axis, included a kinematic diagram symmetrically, that ensures the absence of pressure on the piston cylinder wall by the action of gas pressure forces on the piston during rotation of the crankshaft. Rods are arranged diagonally intersect in different planes and are pivotally connected to the ends of a two-armed lever, which is loosely seated on the crank of the crankshaft, whereby movement of the pistons is obtained, ensuring more efficient thermodynamic cycle, reducing the second order forces of inertia, reducing the height of DBC.
