Injini, i-motor ngumatshini onokuguqula ezinye iindlela zamandla zibe ngamandla omatshini, kubandakanywa iinjini zokutsha zangaphakathi (iinjini zepetroli, njl. njl.), ii-injini zokutsha zangaphandle (ii-injini ze-Stirling, ii-injini ze-steam, njl. njl.), ii-motor zombane, njl. , iinjini zokutsha zangaphakathi zidla ngokuguqula amandla ekhemikhali abe ngamandla oomatshini.I-injini isebenza kuzo zombini izixhobo zokuvelisa amandla kunye nomatshini wonke kubandakanya isixhobo samandla.I-injini yazalwa okokuqala eNgilani, ngoko ke ingcamango ye-injini ivela kwisiNgesi.Intsingiselo yawo yantlandlolo ibhekisa “kwisixhobo somatshini esenza amandla.”

Umzimba ngumathambo e-injini kunye nesiseko sofakelo kwiindlela ezahlukeneyo kunye neenkqubo ze-injini.Zonke iindawo eziphambili kunye nezixhobo ze-injini zifakwe ngaphakathi nangaphandle kwayo, kwaye ithwala imithwalo eyahlukeneyo.Ke ngoko, umzimba kufuneka ube namandla okwaneleyo kunye nokuqina.Ibhloko ye-injini ubukhulu becala yenziwe ngebhloko yesilinda, i-cylinder liner, intloko ye-cylinder, i-cylinder gasket kunye nezinye iindawo.

Umgaqo wokusebenza we-injini uhlukaniswe kwiindawo ezi-4 zokubetha: i-stroke yokuthatha, i-compression stroke, i-stroke yamandla, kunye ne-exhaust stroke.Ingcali yolondolozo lwe-FAW-Volkswagen Star yachaza ukuba ebusika, i-oyile ye-injini, i-oyile yebhuleki kunye ne-antifreeze kwindawo ye-injini kufuneka ijongwe rhoqo ukuze kubonwe ukuba i-oyile yanele na, yonakele, kwaye lixesha lokutshintsha.Ezi oli zifana negazi lemoto yakho.Umjikelo wokutshintshwa kufuneka utshintshwe ukuze kuqinisekiswe ukuhamba kakuhle kweoli.

Iinjini eziqhelekileyo kubomi bethu bemihla ngemihla ziinjini ezikwiimoto;zahlulwe ngokweenjini zepetroli kunye neenjini zedizili ngokwamafutha ahlukeneyo.Olu hlobo lwe-injini ngokubanzi luqulunqwe “ziindlela ezimbini eziphambili kunye neenkqubo ezinkulu ezintlanu”, ezizezi, i-crank yokudibanisa intonga, uloliwe wevalvu, inkqubo yokubonelela ngamafutha, inkqubo yokuqalisa, inkqubo yokupholisa, inkqubo yokuthambisa, kunye nenkqubo yokutshisa.I-injini ye-diesel ayinayo inkqubo yokutshisa.Izitshisa phantsi kobushushu obuphezulu kunye noxinzelelo ngokufaka i-fuel kwigumbi lokutsha ngendlela yenkungu yoxinzelelo oluphezulu.
