Mukasintha lamba wanthawi / unyolo kapena kusintha nthawi pagalimoto, kumvetsetsa zizindikiro za nthawi pa crankshaft ndi camshaft pulleys ndikofunikira kuti muthe kulondola. Ma Tuner adzafunikanso kudziwa bwino za izi chifukwa ndizofunika kwambiri pakukonza mitengo ya RPM.

Ma injini ambiri adzakhala ndi zilembo ziwiri kapena zitatu pa pulley yamkati ya crankshaft kuti ikhale ndi chizindikiro cha "muvi" pa chipika cha injini. Zizindikiro zofananira nthawi zambiri zimapezeka pamtundu umodzi wa camshaft pulleys. Lamba wanthawi kapena unyolo ukayikidwa bwino, chizindikiro chomwe chimayikidwa pa blockmark pa crankshaft chidzakhala chofanana ndi chizindikiro chokhazikitsidwa ku camshaft ndi mutu. Cholinga chokhazikitsa nthawi ndikuti mzerewu uchitike.

Chizindikiro chapamwamba chakufa (TDC) chikhoza kukhala chapakati, kumanzere, kapena kumanja, kutengera injini. Pa injini zambiri, ndiye pakati pa ma mark atatu, koma galimoto yanu yeniyeni imatha kusiyana, choncho yang'anani bukhu la eni anu ndi/kapena zokonza sitolo.
