Umsebenzi we-stroke we-injini ye-diesel ugqityezelwa yi-cylinder nganye ngokulandelelana, ngoko ke amandla asebenza kwi-crankshaft nawo aphakathi kwaye akalingani. Ukuze udlulise le mikhosi kakuhle, ukujikeleza kwe-crankshaft ngokwayo kufuneka kuzinzile. Ukuze uzinze, i-crankshaft kufuneka ilinganise. I-crankshaft inxulumene nokucwangciswa kwenani leesilinda.

Kwii-crankshafts zeenjini zedizili ezintathu, ezine, ezintlanu, kunye neesilinda ezisixhenxe, iintsimbi zedizili ziyafuneka ukuze i-crankshaft ifumane ubunzima obulinganayo. Ubungakanani kunye nokuma kobunzima bokulinganisela kubalwa ngexesha loyilo. Uninzi lwemilinganiselo ye-balance ye-crankshafts idityaniswe kwi-crankshaft xa isenziwa okanye iphosa. Kwinye. Nangona kunjalo, ubunzima beenjini zedizili bubotshelelwe kwi-crankshaft. Ngenxa yomthamo omkhulu wolu hlobo lwebhloko yebhalansi, i-bolt fasting isoloko isetyenziswa xa indawo yokufakela ingonelanga.

Kwi-injini yedizili ene-cylinder ezintandathu ene-crank angle ye-120, i-balance effect ilungile. Kubonakala ngathi akukho mfuneko yokufaka ubunzima bokulinganisela. Nangona kunjalo, le bhalansi sisiphumo samandla e-inertia kwi-crankshaft okanye ibhloko yesilinda. Ngokubhekiselele kwi-injini ye-diesel, kusekho amandla amaninzi angenayo, ngamanye amaxesha abangela ukuba i-bearing engundoqo ilayishwe kakhulu okanye ibhloko ye-cylinder ingcangcazele.

Ukuze ugweme ukungaphumeleli okunjalo, inxalenye nganye ye-crankshaft ine-inertial force enkulu, ngoko kusekho i-balance block. Kwimilinganiselo yokulinganisa ebotshelelwe ngeebholiti, xa i-crankshaft ifuna ukucolwa, iintsimbi zokulinganisa kufuneka zisuswe kwaye zimakishwe ukuze kuthintelwe ukufakela okungachanekanga ekuphuleni ibhalansi xa kufakwa kwakhona.
