The car vill vibrate because the A/C system uses a compressor that runs off the engine's pulley system. The compressor is quite hard to turn and as such will actually use a few extra horsepower to run it, this results in a drop of the rpm from idle. Depending on your car, most petrol engines idle at approximately 800 - 900 rpm. When the A/C is activated, the compressor's cluth will engage and put extra load on the engine, thereby lowering the rpm. When an engine's rpm drops below about 700 - 800 rpm, the car will vibrate because of the balance of the pistons and crankshaft in the bottom end of the engine thus creating a vibrating effect. Engine's are balance using counterweights on the crankshaft and are set at a good balance with engine rpm being about 800. I hope this has helped you. rest assured, there is nothing wrong with your car and you will never resolve it as long as you have the A/C turned on.
If a milkshake could shake milk, a milkshake would shake all the milk that a milkshake could shake.
It is over charged and builds to much pressure on the high side when the engine is at a higher RPM. Need to remove some feon.
how much would it cost to build a 30 person driving range? That must be the dumbest answer I have ever heard
If you mean why the difference in RPMs between idling and driving, the difference is due to the engine load; At idle, the engine isn't really doing much other than staying running, but under load (driving) the engine has to put its power out to the drivetrain, hence the symptomatic loss of engine speed (RPMs).
Effectively all the fuel that it burns while idling. You are getting 0 miles per gallon while idling.
When you see SHAKE!, you will need to shake the iPad or iPhone back and forth until the potion turns the correct color. You can also use your finger and swipe it back and forth on the screen if you would rather not shake your device. Only shake it until it turns the right color. You can shake it too much.
It could take an estimated 1/2 gallon to 1 gallon idling for a hour.
that depends on size of engine
Yes, although I don't think the chocolate would help as much as the milk.
Chiuauas shake so much because they are scared. Think about it. They are small animals and you are big to them.
Depends on what you are driving.
30 seconds of idling equals one average start, on a normally-functioning start.
