FIELD: engines and pumps.
SUBSTANCE: invention can be used in automotive industry. Proposed engine 100 comprises top link 13, bottom link 14 and control link 15. Top link 13 is articulated with piston 11 by means of piston pin 16. Bottom link 14 is fitted to revolve on crankshaft crank pin 12A and is engaged with top link 13 by top pin 17. Control link 15 is coupled with bottom link 14 by control pin 18 are pivoted on control shaft articulated section 21. Links 13, 14, 15 are arranged so that inertial forces of 2nd or higher order act on, at least, top link 13 and control link 15 across engine 100 with the sum of left-hand and right-hand inertial forces of 2nd or higher order equal, in fact, to zero.
EFFECT: reduced vibration.
