Баш ги читав статиите Гојдо што ги пиша. Ама таму секаде пишува за потрошувачка, согорување, CO2, разлики меѓу инџекшн и карбуратори. А никаде не пишува за последиците од работењето во неработна температура и како се деформираат деловите при брзо загревање и брзо ладење.
Изгледа не си читал доволно внимателно:
"3. Idling hurts the car
( . . . ) 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." ( . . . ) idling causes carbon residues to build up inside the engine, which reduces its efficiency."
Зависи што и од каде читаш. Читаме тврдења кои не се поткрепени (и тоа што го пишува на интернет не е агранција дека е точно) и тоа не значи дека треба слепо да им веруваме. Затоа јас велам дека здравата логика и познавањето на фундаментите на работите се покорисни отколку сурфање п некои шкљ сајтови хостирани кај перо дома или кој знае каде. На пример:
* It's common practice, here in the great white north, to let your car warm up before driving. I don't think one could go a single winter without hearing a warning to let your car warm. Though, possibly our winters are much more harsh than yours. In the true great white north, Canada, at least in Quebec, there are warmers placed on cars overnight.
It's so ingrained in me, I can't even contemplate driving off without warming my car first, in winter. Though, in Michigan, even if you clear the exterior of ice and snow, if you don't let your window defroster run for a bit, you're not seeing to go anywhere, anyway.
* My father was a certified mechanic, granted this was years ago, but he told me never to take off until the car had idled down. When you first start a car it idles fairly fast then slows a bit and you should never take off until it reaches that point. He said the oil needs to get from the oil pan into the engine to protect it. He never mentioned anything about this hurting the car in anyway.
Another fine reason for letting it warm up is to make sure your windows are clear. In Georgia they ticket peephole drivers. (those with just a little area they can see out of on the windsheild)
* Cold running engines tend to sludge-up. If you run it like this for any length of time you'll need to also change the oil.
* Most new engines are ABC, meaning 3 diferent metals and in order to run the engines they need to be at 200F, this is where all the metas have expanded to there operating temps, actualy running an ABC engine below optimal temp is just as bad if not worse than overheating.
* Cold engines emit far higher percentages of unburned hydrocarbons than warm engines do. Sadly still, the average catalytic converter isn't able process 100% of unburned hydrocarbons, even at the best of times. Also, catalytic converters need higher exhaust temperatures to work properly.
Throw in a cold engine emitting a high percentage of unburned hydrocarbons, repeated thousands of times, and you may end up with a "plugged" converter.
Basically, the converter becomes overwhelmed and literally ceases to function. This will happen over long time, and the end effect is: poor mileage and much dirtier exhaust.
Your best bet? Even when it's 10 degrees outside, is to start your car, let it run for 30 to 60 seconds enough to get all the fluids running, and drive off gently. Your engine will warm up faster, your exhaust system will get up to temperature faster so the cars catalytic converter can do its job, and you'll use much less fuel. Which is what we all wanted all along?
If it's below zero degrees, it's good to give the engine five minutes or a bit less before you drive off into the frozen surroundings.
Некаде се спомнуваат некои работи некаде се преќутуваат, што ме тера да помислам дека се маргинално битни односно се речиси небитни.
А маслото во менувачот се загрева од моторот преку трансфер на топлина од блокот на моторот. Ако некој возел кола со термометар за масло ќе знае дека темературата на маслото во менувачот доцни некаде 2-3 минути зад температурата на моторот, така да тоа и не е така голем проблем.
