Kurongeka kweinjini dzemotokari kune marudzi anotevera:

1. Zvinoenderana nerudzi rwesimba, injini dzemotokari dzinogona kukamurwa kuita injini dzedhiziri, injini dzepeturu, mota dzemagetsi, uye mahybrids.

2. Zvinoenderana nechikamu cheiyo intake system, inogona kukamurwa kuita mhando ina: natural aspirated, turbocharged, mechanical supercharged uye dual supercharged.

3. Zvinoenderana nepiston kufamba modhi, inogona kukamurwa kuita inodzokorodza piston yemukati injini yekupisa uye rotary piston injini.4. Maererano nemhando yegadziriro ye cylinder, kune in-line injini, V-mhando injini, W-mhando injini uye horizontally inopikisa injini.

5. Maererano nenhamba yemasilinda, inogona kugoverwa kuva imwe-cylinder injini uye yakawanda-cylinder injini. Mota dzemazuvano dzinonyanya kushandisa injini dzemasilinda, mana-cylinder, matanhatu-cylinder, uye masere-cylinder.

6. Maererano nenzira dzakasiyana-siyana dzekutonhora, inogona kugoverwa mumvura-inotonhorera injini uye injini yemhepo inotonhorera.

7. Maererano nenhamba yekurohwa, inogona kugoverwa kuva ina-stroke mukati mejini inopisa uye maviri-stroke mukati mejini inopisa.

8. Zvinoenderana neyakagadzika yemafuta ekugovera modhi, carburetor injini, yemagetsi jekiseni injini uye yakananga jekiseni injini muhumburumbira.
