Title:DiagnosisandCleaningMethodsforEngineCarbonDeposits
Introduction:
Theaccumulationofcarbondeposits,commonlyknownasenginecarbon,isacommonproblemininternalcombustionengines.Whencarbondepositsbuildupintheengine,theycanaffectitsperformance,reducefuelefficiency,andincreaseemissions.Therefore,diagnosingandeffectivelyremovingcarbondepositsarecrucialtomaintainingoptimalengineperformance.Thispaperaimstoexplorethediagnosisandcleaningmethodsofenginecarbondeposits.
I.DiagnosisofEngineCarbonDeposits:
1.SymptomsofEngineCarbonDeposits:
-Roughidleandenginemisfire
-Reducedaccelerationandpower
-Decreasedfuelefficiency
-Increasedexhaustemissions
-Unpleasantexhaustodor
