Mafuta osinthika
Kuchita bwino kwa mpope wamafuta, komwe kumawonjezeka mwachangu, kumatanthauza kuti makina opaka mafuta sangathe kugwiritsa ntchito mafuta onse. Kuthamanga kwa mafuta kuyenera kukhala kochepa.
Mu dongosolo lapamwamba lopaka mafuta, valavu yoyendetsera makina imagwiritsidwa ntchito pachifukwa ichi, yomwe imatsegulidwa pamene mulingo wina wopanikizika wadutsa. Choyipa cha yankho ili ndikuti, ngakhale kupsinjika kwachepa, pampu yamafuta ikupitilizabe kugwira ntchito mokwanira. Kuonjezera apo, kupopera mafuta kudzera mu valve yolamulira kumafuna kutulutsa mphamvu, yomwe imasandulika kutentha kosafunikira.
Njira yothetsera mavuto omwe amabwera ndi njira iyi yoyendetsera kupanikizika mu dongosolo lopaka mafuta ndi pampu yomwe imatha kupanga miyeso iwiri yosiyana. Yoyamba, yotsika, imayang'anira dongosolo mpaka liwiro linalake, kupitirira apo pampu imasinthira kumtunda wapamwamba. Chifukwa chake, dongosolo lopaka mafuta limalandira ndendende kuchuluka kwamafuta omwe amafunikira kuti apititse patsogolo kuthamanga kwamafuta momwemo.
Kuthamanga kwa mafuta kumayendetsedwa ndi kusintha pampu. Zimapangidwa ndi kusuntha kwa axial kwa zida zopopera zomwe zimapangidwira kunja. Zikakhala zotsutsana ndendende, mphamvu ya mpope ndiyokwera kwambiri. Kusuntha kwa axial kwa mawilo kumapangitsa kuchepa kwa mphamvu ya mpope, chifukwa kuchuluka kwa mafuta opopera kumadalira kukula kwa malo ogwirira ntchito a mawilo.
Mu injini yosinthidwa motere, pampu yamafuta imagwiritsa ntchito sensa yowonjezera yachiwiri yomwe imalembetsa kutsika kwapang'onopang'ono, yomwe nthawi yomweyo imayang'ana ngati pali kupanikizika mu dongosolo lopaka mafuta. Chitsanzo cha ma powertrains amenewa ndi matembenuzidwe osinthidwa a injini za 1,8L ndi 2,0L TFSI zinayi zamphamvu zokhala ndi nthawi.
