Kutentha kwa injini
Chizindikiro chake ndi chimodzi mwazinthu zofunika kwambiri pamaziko omwe gawo lowongolera injini limawerengera mtengo wanthawi yomweyo wanthawi yoyatsira ndi mlingo wamafuta ojambulidwa.
M'magalimoto amakono, kutentha kwa injini kumayesedwa ndi sensor ya NTC yomwe ili mkati 
injini yozizira. Chidule cha NTC chikuyimira Negative Temperature Coefficient, i.e. Pankhani ya sensa yotereyi, kukana kwake kumachepa ndi kutentha kwakukulu.
Kutentha ndi gawo lowongolera powerengera nthawi yoyatsira ndi gawo lowongolera injini. Popanda chidziwitso cha kutentha kwa injini, mtengo wolowa m'malo umagwiritsidwa ntchito powerengera, nthawi zambiri 80 - 110 digiri Celsius. Pankhaniyi, kuyatsa patsogolo angle amachepetsa. Chifukwa chake, mota imatetezedwa kuzinthu zambiri, koma magwiridwe ake amachepetsedwa.
Mlingo woyambira wa jakisoni, womwe umatsimikiziridwa kutengera liwiro la injini ndi katundu, mugawo lozizira loyambira, komanso m'malo ena ogwiritsira ntchito, uyenera kusinthidwa moyenera. Mapangidwe a osakaniza amasinthidwa, mwa zina, malinga ndi chizindikiro chochokera ku sensa ya kutentha kwa injini. Ngati palibe, mtengo wolowa m'malo wa kutentha umatengedwa kuwerengera, monga momwe zimakhalira poyatsira moto. Komabe, izi zimatha kuyambitsa zovuta (nthawi zina ngakhale zosatheka) komanso kugwira ntchito mosagwirizana kwa ma drive unit panthawi yotentha. Izi zili choncho chifukwa kutentha m'malo nthawi zambiri kumatanthauza injini yotentha kale.
Ngati palibe mtengo wolowa m'malo, kapena pali kachigawo kakang'ono kamene kamakhalapo, ndiye kuti kusakaniza sikupindula, chifukwa dera lalifupi, i.e. otsika kukana dera, limafanana ndi injini yotentha (NTC sensa kukana amachepetsa ndi kuwonjezeka kutentha). Momwemonso, dera lotseguka, i.e. kukana kwambiri, kuwerengedwa ndi woyang'anira ngati kuzizira kwambiri kwa injini, zomwe zimapangitsa kuti mlingo wa mafuta ukhale wolemera kwambiri.
Sensa yamtundu wa NTC imagwira ntchito bwino poyesa kukana kwake, makamaka pazigawo zingapo pamawonekedwe ake. Izi zimafuna kutentha dala kwa sensa ku kutentha kwina.
