METHOD OF AND ENGINE FOR OPERATION ACCORDING TO MECHANICAL CYCLE Russian patent published in 2005 - IPC

FIELD: power engineering.

SUBSTANCE: invention can be used in internal combustion engines, heat machine and power plants for converting reciprocating motion into rotation. Proposed method includes processes of compression and/or expansion with displacement of working members which is done by mechanisms containing crank. Expansion is provided by mechanisms with absolute energy parameters greater than those of mechanisms by means of which compression is done, and absolute energy parameters of mechanisms are chosen from equation A(λ_i,ρ_i,…)ϕ>A(λ_i,ρ_i,…)ψ where A is absolute energy parameter of mechanism containing crank; λ_i,ρ_i,…are relative values of links of mechanism containing crank providing asymmetrical displacement of working members in angle of crank turning. ϕ is angle of turning of crank of mechanism executing expansion or working stroke; ψ is angle of turning of crank of mechanism executing compression or preparatory stroke. Engine for implementing proposed method contains at least two cylinders with pistons mechanically connected through connecting rods with crank. First cylinder has offset, and second cylinder, axial slider-crank mechanisms. Mechanism of first cylinder is made with energy parameter greater than that of mechanism of second cylinder. Cylinders are interconnected by bypass channel which can be closed.

EFFECT: increased efficiency.
