Lubrication သံုးတတဲ့ ရယ္ရြယ္ခ်က္၃ခ်က္?
A
၁ moving parts ေတြၾကားပြတ္တိုက္ပ်က္စီးမူနည္းၿပီးengine သက္တမ္းရွည္ေအာင္.
၂ sealing action ကိုအေထာက္အကူျပဳေအာင္
၃ components ေတြကေနထုတ္လိုက္တဲ့အပူကို အေ၀းကိုသယ္ေဆာင္ေပးျခင္းျဖင့္ မ်က္ႏွာျပင္ေတြေအးေအာင္
၄ carbonေတြနဲ႔ သတၳဳအစအနေတြကို အေ၀းသႎု႔ဖယ္ရွားျခင္းျဖင့္ မ်က္ႏွာျပင္သန္႔ရွင္းေအာင္
