Cars warm up to a temperature higher than the surroundings because of the glass in the car windows. This is called the greenhouse effect. High-energy heat waves from the sun are able to pass through the glass of the windows, and this energy is absorbed by the materials inside the car, causing it to heat up. The glass does not let the less energetic heat waves being let off by the warm car pass through the windows. Therefore the heat is "trapped" inside the car, causing it to get warmer than the surroundings.
No. Cars no longer need it.
There is no set amount of gas that is used to warm up a car. Different cars use different amounts of gas.
well you should let it warm up for a minute I know my dirt bike will stall if I don't let it warm up but cars not so much
We closed it.
Zero. Modern gasoline engined cars have no warm-up time requirement. Diesels, and air-cooled engines have various requirements.
yes , it requires min 20 sec for oil circulation in side the engine
that's not true. Any vehicle will "warm up" as long as the engine is running. Does not matter whether its at idle "running at a stop" or driving around town. The olders cars (1995 and beyond) require about 5min of warm up before drving. Cars now days don't require any. You can fire them and drive it like you stole it!
It all depends on what kind of driving you plan on doing if you are trying to go 0 - 60 i would recomend warmining it up. If it is winter most people warm up their cars so it's not like an ice box!
Most (not all) cars are heated by the engine. When fluid moves through the engine it heats up. This fluid moves through the heater core, a fan moves air over the warm heater coils blowing warm air out to the cars cab.
Your cars power steering pump has to warm up for a little while to stop it.
Most cars made past 1980s have no true need to warm up anymore due to the all season oils but most people who believe they do say 5-10 mins
Means your trunk isn't closed properly
