http://answers.yahoo.com/question/index?qid=20081009045451AAsrTgNThere have been a few answers here that are correct and some not fully explained and ONE that is simply wrong.
Your wanting to keep your engine in top shape is highly admirable and quite impressive that a woman would be so concerned. If I may try to explain the workings of an engine simply.
An automobile engine needs to work at temperatures from far below zero up to hundreds of degrees driving through the desert at 120 degrees. The engines are put together with clearances between moving parts. There are a number of places for these clearances and each has certain tolerances. The distance between the piston skirt and the cylinder for example of
.002 (two thousands). This tolerance changes between vehicles depending upon the composition of the piston and the cylinder wall. In all instances this clearance is set at what is called “cold”. If the clearance is too far (
say .004) you could get “piston slap” at warm up. If too tight the engine would seize at operating temperature.
There are such clearances required at all moving parts such as Main bearings, Rod bearings, valves ETC.
When you start a engine that is ‘cold’ these parts need to warm up to operating temperature and during this time there is a substantial wear on all these parts. As a matter of fact starting a cold engine and running it up to operating temperature puts as much ‘wear’ on an engine as driving it 10,000 miles at operating temperature. Тоа што апла сакам да го кажам не можам да го најдам апла кажано на интернет. Кој ќе сфати ќе сфати. Кој не нека е жив и здрав. Кој ќе биде доволно упорен да го најде на интернет нека го постира, ќе го частам пиво и мезе. Јас немам намера да потрошам часови за да го најдам.
„„idling forces an engine to operate in a very inefficient and gasoline-rich mode that, over time, can
degrade the engine's performance and reduce mileage.““ Да, и баба ми знае така. Не гледам објаснување ЗОШТО е тоа така. Така да со такви изјави (од чиј тип се сите горе наведени) ништо не кажуваат во врска со темата на разговор.
