Ijenali ye-crankshaft kanye nesihlahla esithwalayo kugqokwe kakhulu, futhi kujwayelekile ukuthi ijenali ye-camshaft igqokwe kancane.

Uhlu olufushane lumi kanje:

1. Ubudlelwano phakathi kwesivinini se-crankshaft nesivinini se-camshaft ngokuvamile bungu-2:1, isivinini se-crankshaft singu-6000rpm, kanti isivinini se-camshaft singu-3000rpm kuphela;

2. Izimo zokusebenza ze-crankshaft zimbi nakakhulu. I-crankshaft idinga ukwamukela amandla adluliswa ukunyakaza okuphindaphindayo kwepiston, iguqule ibe yitorque, bese ishayela imoto ukuze ihambe. I-camshaft iqhutshwa yi-crankshaft futhi ishayela i-valve ukuze ivule futhi ivale. Amandla ahlukile.

3. Ijenali ye-crankshaft inamaphedi anezinhlamvu, futhi ijenali ye-camshaft ayinawo amaphedi okuthwala; imvume phakathi kwejenali ye-crankshaft kanye nembobo ngokuvamile incane kunaleyo yejenali ye-camshaft kanye nomgodi. Kungabonakala futhi ukuthi imvelo yejenali ye-crankshaft yimbi nakakhulu.

Ngakho-ke, kuyaqondakala ukuthi i-crankshaft igugile kakhulu futhi iphephabhuku le-camshaft ligugile kancane.

Ngenxa yokuthi angikaze ngibone izithombe zokugqoka okubucayi, ngingakhuluma kafushane kuphela ngezizathu ezingase zibe khona. Isibonelo, i-coaxiality ye-cap bearing cap ayilungile, okuholela ekugqokeni okungavamile kwejenali kanye nesihlahla esithwalayo; umfutho kawoyela uphansi, futhi awekho ifilimu kawoyela eyanele kujenali, okungenzeka ukuthi nayo igqoke ngendlela engavamile.
