Injini inopisa yomukati inoshanda sei?
Musimboti womotokari ine injini inopisa mukati (push rod internal combustion engine kana kuti ICE) inonzi crankshaft. Matanda anobatanidza mapistoni enjini nemapepanhau e crankshaft. Crankshaft inonyatsoenzaniswa nehuremu pamativi anopesana ebhuku rimwe nerimwe kuti ave nechokwadi chokuti pakutenderera kwakakwirira paminiti (RPM) injini yakagadzikana. Sezvo crankshaft inotenderera inosundira tsvimbo kumusoro nokudzika dzakabatana nemapistoni. Pamberi pe crankshaft pane giya, iro giya rinowanzobatanidzwa kuburikidza neketani kune camshaft. Kana crankshaft iri mwoyo wemota, camshaft uropi hwemota. Camshaft ndiyo inosarudza nguva yokuvhura nokuvhara mavharuvhu anoita kuti mhepo nepeturu zvipinde musirinda imwe neimwe uye zvinoburitsa gasi rinobuda pakupisa mukati. Camshaft shaft rinomhanya kureba kweinjini uye rine ma lobes pairi, masirinda maduku esimbi anonzi ma lifters anotasva pama lobes aya uye akabatanidzwa kumapush rods, mapush rods akabatanidzwa kuma rockers ayo anofamba mberi neshure kuvhura nekuvhara mavharuvhu mumisoro yesilinda. Mavharuvhu acho ari mumisoro yesilinda iri pamusoro pesilinda dzine mapistoni. Sezvo mapistoni anotenderera kumusoro, vharuvhu (iri kufambiswa ne camshaft) inovhura kuunza mafuta mu cylinder, apo vharuvhu inovhara spark kubva ku spark plug, inopisa mafuta anokonzera kuputika kudiki kunosundira cylinder pasi, vharuvhu yechipiri inovhura ichirega mweya wekubvisa kubva mukuputika kudiki kubuda muinjini. Izvi zvinobva zvaita kuti crankshaft itenderere mberi ichisundira imwe pisitoni kumusoro uko muitiro wacho unopfuurira. Mudziyo wokubudisa mweya wakafanana nemapapu emotokari, unofema mhepo inobva mumhepo yakapoteredza pasi uye unoisanganisa nemafuta akakwana chaizvo kuti iite kuputika kuduku mukati mechirongo. Nguva yokuendesa mhepo, peturu, chivheneko inokosha zvikuru kana ikangobviswa pamuganhu muduku zvikuru injini haisati ichizotongofamba.
