Cholinga cha pampu yozizira

Njira zoziziritsira injini zamadzimadzi (kapena ayi, hybrid) zimagwiritsa ntchito madzi okhala ndi zowonjezera kapena antifreeze osazizira ngati choziziritsira.Chozizira chimadutsa mu jekete lamadzi (kachitidwe ka zibowo m'makoma a silinda ndi mutu wa silinda), kuchotsa kutentha, kulowa mu radiator, komwe kumatulutsa kutentha kumlengalenga, ndikubwereranso ku injini.Komabe, choziziritsa choziziriracho sichingayende paliponse, kotero kuti kuzizira kozizira kumagwiritsidwa ntchito m'makina ozizirira.
Pakuzungulira, mapampu ozungulira amadzimadzi amagwiritsidwa ntchito, moyendetsedwa ndi crankshaft, shaft yanthawi kapena injini yophatikizika yamagetsi.
M'mainjini ambiri, mapampu awiri amaikidwa nthawi imodzi - pampu yowonjezera imafunika kuti iyendetse zoziziritsa kudera lachiwiri, komanso m'madera ozizira a mpweya wotulutsa mpweya, mpweya wa turbocharger, ndi zina zotero. mu njira yozizirira yapawiri-circuit) imayendetsedwa ndi magetsi ndipo imayatsidwa ikafunika.
Mapampu oyendetsedwa ndi crankshaft (pogwiritsa ntchito V-belt drive, nthawi zambiri amakhala ndi lamba umodzi, pampu, fan ndi jenereta amayendetsedwa mozungulira, kuyendetsa kumayendetsedwa kuchokera ku pulley kutsogolo kwa crankshaft);
- Mapampu oyendetsedwa ndi shaft yanthawi (pogwiritsa ntchito lamba wa mano);
- Mapampu oyendetsedwa ndi mota yawoyawo yamagetsi (nthawi zambiri mapampu owonjezera amapangidwa motere).

Mapampu onse, mosasamala kanthu za mtundu wa galimoto, ali ndi mapangidwe ofanana ndi mfundo yogwiritsira ntchito.
