Is idling bad for your engine?

처리 내용

Aside from financial and environmental considerations, U.S. and Canadian governmental agencies say that idling produces various negative effects on engine components. During idling engine does not work at its most efficient mode, and the fuel combustion is incomplete. That leads to glazing of combustion chamber and reducing effectiveness of spark plugs in petrol engines (plugs with heavy deposits can foul, and that can increase fuel consumption by 4 to 5%). Also petrol can contaminate the motor oil which reduces its lubricating qualities (that could mean more frequent oil changes and/or increased wear on the engine). Also, as the engine runs at less than ideal operating temperature, which causes water vapour (a product of combustion) to accumulate in exhaust system (at proper temperature and at higher speed of exiting gasses caused by increased RPMs it clears out pretty good), which leads to corrosion. Also, idling produces up to 10–12% more emissions than driving for the same amount o
