Abstract

Sposób kompensacji luzu zaworowego przeznaczony jest do zastosowania w silniku spalinowym o zmiennym stopniu sprężania, z przesuwem równoległym zespołu cylinder-głowica (2) względem kadłuba (1) silnika, posiadającym wałek rozrządu w kadłubie (1) silnika i ruchomy zespół cylinder-głowica (2). W sposobie, będącym przedmiotem wynalazku, przy zmianie stopnia sprężania silnika i równoległym przesuwie zespołu cylinder-głowica (2) względem kadłuba (1) silnika w górę albo w dół, przesuwa się pierwszą oś (4) dźwigienek zaworowych (3) w kierunku przeciwnym, za pomocą mimośrodu napędowego (6). Urządzenie do stosowania sposobu kompensacji luzu zaworowego zamocowane jest na zespole cylinder-głowica (2), który jest przesuwny względem kadłuba (1) silnika i zawiera pierwszą oś (4) dźwigienek zaworowych (3), która jest łożyskowana w mimośrodach prowadzących (8) oraz mimośrodach napędowych (6). Mimośrody napędowe (6) poprzez korbowody napędowe (5) połączone są z kadłubem (1) silnika.The method of valve clearance compensation is intended for use in a combustion engine with a variable compression ratio, with parallel displacement of the cylinder-head assembly (2) relative to the engine block (1), having a camshaft in the engine block (1) and a movable cylinder-head assembly (2). ). In the method, which is the subject of the invention, when the engine compression ratio is changed and the cylinder-head unit (2) moves parallel to the engine block (1) up or down, the first axis (4) of the rocker arms (3) moves in the opposite direction, by means of the drive eccentric (6). The device for applying the valve clearance compensation method is mounted on the cylinder-head assembly (2), which is movable relative to the engine block (1) and contains the first axis (4) of the rocker arm (3), which is mounted in the eccentric guiding (8) and drive eccentrics (6). The drive eccentrics (6) are connected to the engine block (1) via drive connecting rods (5).
