Mtundu wogwiritsa ntchito umapereka chiwembu chotsatirachi: cholumikizira cholumikizira mwachindunji chopanda mafuta chimakhala ndi chopukutira, chopukutira cholumikizidwa mozungulira mozungulira mu crankcase, kumapeto kwake kwa crankshaft kumalumikizidwa ndi mota, kumapeto kwina kwa crankshaft kuli ndi fani, cholumikizira chimaphatikizidwa pamwamba pa crankcase, cholembera chimayikidwa pachimake, pisitoni ya mpweya wothinikizidwa imakonzedwa mu silinda, ndipo pisitoni imayendetsedwa ndikulumikizidwa ndi crankshaft, The crankcase is cylindrical zimakupiza zili mu crankcase ndipo ndi zophatikizana ndi crankcase, blocking block imaperekedwa ndi mpweya wowongolera dzenje lozizira kunja kwa silinda, bowo lowongolera mpweya limalumikizidwa ndi mkatikati mwa crankcase ndi pamwamba Pamwamba pokhomapo, khoma lammbali lamiyala limapatsidwa choziziritsira chotentha, njira yotulutsira kutentha imapangidwa pakati pa lakuzimitsa ndi khoma lakunja la silindalo, ndi bowo lowongolera mpweya ikukumana ndi njira yotaya kutentha.

Mtundu wokonda kugwiritsa ntchito: cholembacho ndi chozungulira, choyikirako chimakhala chamakona anayi, pakatikati pa choyikapo chimaperekedwa ndi bowo lolumikizira silinda, bowo lowongolera mpweya lili mbali zonse ziwiri za dzenje lolumikizira, ndi chowongolera mpweya dzenje Amawapatsa stiffeners.

Mtundu wothandiza makamaka uli ndi maubwino otsatirawa: makulidwe amakoma mbali zonse ziwiri za dzenje lowongolera ndi ofanana.

Makonda omwe amagwiritsidwa ntchito ndikuti crankcase ndi silinda amapangidwa ndi aluminium.

Poyerekeza ndi luso lapitalo, phindu la mtundu wogwiritsa ntchito ndikuti crankcase ndiyosakanikirana, zimakupiza zili mu crankcase ndi coaxial ndi crankcase, ndipo zimakupiza zimakhazikika kumapeto amodzi a crankshaft. Chovundikiracho chikazungulira, pisitoni yoyendetsa imayenda chokwera ndi chotsikiracho mu silinda kukanikiza mpweya. Nthawi yomweyo, zimakupiza zomwe zimayikidwa pa crankshaft zimazunguliranso limodzi kuti zipange kutuluka kwa mpweya, Kutuluka kwa mpweya kumazizira khoma lakunja la silinda kudzera pa bowo lotsogolera mpweya. Chophimbacho chimakhala chachitsulo. Poyerekeza ndi crankcase yamakona anayi, trapezoidal ndi mawonekedwe ena, kukana komwe kumapangidwa ndi kutuluka kwa mpweya ndikochepa. Chowonera chimapezeka mu crankcase komanso coaxial ndi crankcase. Mtunda kuchokera kumphepete kwakunja kwa fani kupita kukhoma lamkati la crankcase ndi yunifolomu komanso yosavuta kuwongolera munthawi yaying'ono, yomwe imatha kupititsa patsogolo kuthamanga kwa mpweya, Khoma lakunja la silinda lakhazikika bwino, ndipo dzenje kalozera mpweya chikugwirizana mwachindunji ndi kutentha madyaidya ndikuledzera yamphamvu ya

Kutulutsa kwamlengalenga komwe kumapangidwa ndi zimakupiza kumatha kugwiritsidwa ntchito bwino kuziziritsa khoma lakunja la silinda.
