Dufite itsinda ryabatekinisiye babigize umwuga bagize uruhare runini rukora impeta ya piston hamwe na silinderi nini ya silinderi, kandi bafite inshingano zo kwizigira tekiniki yubuhanga bwikigo. Kuva mu bikoresho fatizo binjira mu ruganda mu bicuruzwa bivuye mu ruganda, uburyo bwo kuyobora bugezweho bwemejwe kugira ngo hakurikirane ireme rya buri murongo no kwirinda ibicuruzwa bifite inenge bitembera inzira itaha. Isosiyete ishyira mubikorwa sisitemu yo kugenzura gatatu ubugenzuzi bukomeye: Kwifashisha, ubugenzuzi hagati, kandi bikomeza gukurikirana inyandiko zumwimerere kugirango tumenye ko buri mpeta ya buri piston ava mu ruganda.
