Iimoto zedizili zishiye imbono embi ezingqondweni zabantu, kodwa ubuchwephesha bedizili kudala buphuculwa ukuze bucoceke, bube namandla ngakumbi, kwaye kwezinye iimeko iinjini zedizili zineengenelo ezinkulu kuneenjini zepetroli. Icocekile kwaye i-eco-friendly ngelixa igcina ukusebenza olomeleleyo. Makhe sihlalutye umahluko phakathi kwepetroli kunye neenjini zedizili kuwe.
I-injini ye-diesel ne-petroli zombini zii-injini zokutsha zangaphakathi, nto leyo ethetha ukuba zombini zingenisa amafutha e-injini, ziyixube nomoya, ziwucinezele, ziwuvuthe ngeendlela ezahlukeneyo, emva koko ziqhube ipistons ezantsi ukujika i-crankshaft, eqhagamshelwe kwi-crankshaft. ukuhanjiswa kwesithuthi, kwaye ekugqibeleni ujike ivili. I-piston inyukela phezulu kwi-cylinder, ityhala iigesi ezivuthayo ngaphandle kwe-injini kunye nombhobho wokukhupha njengombhobho, kwaye lo mjikelo uphindwa kaninzi ngomzuzwana ukufezekisa injongo yokukhupha amandla ngokuqhubekayo.
Umahluko ophambili phakathi kweenjini zedizili nezepetroli yindlela ezikhutshwa ngayo. Kwi-injini ye-petroli, umoya kunye ne-fuel zinyanzeliswa, kwaye kwiindawo ezibalulekileyo kumjikelezo, i-spark plug ivutha umxube. Kodwa kwi-injini ye-diesel akukho ziplagi ze-spark, endaweni yoko, xa idizili kunye nomoya zicinezelwe ngokwaneleyo, ukunyanzeliswa okugqithisileyo kuvelisa ubushushu obaneleyo ukwenza umxube uzitshise. Oku kubizwa ngokuba "yi-compression ignition" kwaye sisiseko sendlela iinjini zedizili ezisebenza ngayo. Iinjini zepetroli nazo zinokusebenzisa ukucinywa komlilo, kodwa ngefuthe kwi-injini ngokwayo, ziinjini zedizili kuphela ezinokuyisebenzisa kakuhle.
