Schwing Drive Slewing Lever

Kusonkhana kwa rocker arm kumayambitsa kusakaniza koyaka (kapena mpweya wabwino) mu silinda; kenako amapaka chisakanizo choyaka (kapena mpweya wabwino) mu silinda, ndikuyatsa chosakaniza choyaka pamene kuponderezedwa kuli pafupi ndi mapeto (kapena jekeseni dizilo mu silinda kuti mupange chisakanizo choyaka ndi kuyatsa); chisakanizo choyaka chimayaka ndikuyaka, ndipo kukulitsa kumakankhira pisitoni pansi kuti ikwaniritse ntchito yakunja; potsiriza, mpweya wotuluka pambuyo pa kuyaka umatulutsidwa . Ndiko kuti, mpweya, psinjika, ntchito, utsi njira zinayi. Ndiwonso gwero lamphamvu lagalimoto

Njira zopangira mabuleki a injini zimaphatikizirapo mabuleki a exhaust, braking air release and compression release braking. Injini imatenga psinjika kumasulidwa braking mode, ndipo mawonekedwe ake ntchito ndi motere:

Ngati palibe braking, valavu ya brake solenoid imazimitsidwa ndipo mbali zina sizingadzazidwe ndi mafuta. Pamene injini imathamangira pamalo a bwana wa brake (ndiko kuti, pamene pisitoni ili pafupi ndi malo okwera pamwamba), chipika chapamwamba cha valve yotulutsa mpweya chiyenera kugonjetsa mphamvu ya masika mu plunger. Panthawiyi, bwana wa brake pa camshaft sagwira ntchito ndipo sangakankhire valve yotulutsa mpweya. Injini imagwira ntchito bwino.

Kapangidwe ka gulu la mkono wotulutsa mpweya: pakafunika mabuleki, yatsani chosinthira cha brake injini, kanikizani chopondapo, ndipo ECU imayendetsa mafuta kuti asiye kupereka mafuta. Panthawiyi, valavu ya brake solenoid imayatsidwa ndikutsegulidwa, ndipo mafuta ochokera munjira yothandizira mafuta mumtsuko wa rocker arm amakwirira njira yolowera mafuta pa rocker arm bushing ndi gawo la mafuta lothandizira la rocker arm, ndikulowa chipinda chopumira cha brake; pamene mafuta mu chipinda cha brake afika kupanikizika kwina, plunger imayendetsedwa kuti ipite mmwamba, ndipo valavu yoyang'ana imatsekedwa, kotero kuti chipinda cha brake chidzadzazidwa ndi mafuta. Chifukwa mafuta a injini ndi osasunthika, injini ikathamangira pamalo pomwe pali ma brake bwana (ndiko kuti, pisitoni ikakhala pafupi ndi malo oyambira akufa), bwana wa brake pa camshaft amakweza chogudubuza chotulutsa valavu, ndi utsi wa brake. valavu yapamwamba imakankhira valavu yotulutsa mpweya pansi pa mphamvu ya brake plunger exhaust valve rocker arm kuti itulutse gawo la mpweya wothamanga kwambiri. Pistoni ikatsikira, valavu yotulutsa mpweya imatseka, ndipo injini ili mumayendedwe agalimoto yonse Yoyendetsedwa kuti igwire ntchito yoyipa (yofanana ndi pamwamba pa vacuum ya pisitoni), kuti ikwaniritse kukanikiza kwa injini, kumasulidwa. brake. Liwiro la injini likakwera kwambiri, mphamvu ya braking ndi yayikulu.
