Questions and answers about idling
What about diesel engines that have to be warmed up? Excessive idling can actually be hard on the engine because fuel combustion is incomplete and some fuel residues condense on cylinder walls. Will shutting off and restarting the engine so often cause undue wear and tear? Restarting a vehicle several times has little impact on engine parts such as the battery and the starter motor. The cost of associated wear is estimated at $10 per year. |
