Imele ini ngempela i-OHC futhi yini eyenza ihluke?

Kusukela esihlokweni uzothola ukuthi yiziphi izimoto ezazifakwe izinjini ze-camshaft eziphezulu futhi uthole ukuthi yini umehluko phakathi kwe-DOHC ne-SOHC.

injini ye-camshaft ephezulu

Izinjini ze-OHC zibonakala ngohlobo olukhethekile lwesistimu yesikhathi se-valve lapho i-valve drive shaft itholakala khona ngqo ekhanda le-cylinder. Izimoto eziningi zesimanje zisebenzisa izinjini ze-OHC. Kulula ukusebenza, iqhutshwa iketango noma ibhande elinwebekayo elinesondo elinamazinyo.

I-SOHC ifinyelele isiqongo sayo sokuduma

Izinjini ze-SOHC zazidume kakhulu ngawo-XNUMX. Azinasimo esiphuthumayo esincane, zinamandla kune-DOHC, kodwa azizange ziguqule imakethe. Inzuzo yesistimu ye-SOHC ukungabikho kwezinto zesikhathi ezifana nama-pushrods nama-levers okukhiya. Ngenxa yalokhu, injini iyashesha futhi inikeza isivinini esihle kakhulu.

I-DOHC iyisixazululo esiphelele?

Injini ye-DOHC igqame ngokuba namakhamera amaningi afinyelela kwamabili futhi ivamise ukusetshenziswa emhlabeni jikelele ukubhekisela ezinjinini ze-piston lapho ikhanda linama-camshaft amabili. Izinjini ezinalolu hlobo lwesikhathi se-valve yizona ezisebenza kahle kakhulu futhi ezinconyiwe. Banikeza amandla amaningi kakhulu ngokusetshenziswa kancane kukaphethiloli. 

Injini ye-DOHC iyasebenza futhi iyonga, yingakho ithandwa kakhulu ngabakhi bezimoto.
