How much more fuel does an engine use when the car air conditioning is on?

Because of the "drag" caused with windows down, it is usually more beneficial to drive with the windows up and the air on. For more information, check out HowSTuffWorks.com.

How much petrol is used by a car engine when its on but car is not moving?
Sorry but this has way too many unknowns to answer properly. (Engine size, engine temperature, idle or throttled, air conditioning, charged battery, headlights) A few minor trends though can be specified. While an engine is cold, more fuel will be consumed to bring the engine up to temperature. Most modern automobile engines have been designed so lean that when added mechanical loads are engaged like air conditioning, and battery charging; more fuel is consumed to compensate. Older, typically carbuerated engines were set to consume enough fuel at idle to not stall the engine with all mechanical loads engaged.
Does car air conditioning burn more gas?
Yes, it causes the engine and the charging system to work much harder. I would say it will cost you at least 10% in fuel efficiency. On cooler days it would be much more economical to drive with the windows down or with the fan on without using the a/c compressor
On most cars is a 4-cylinder engine more fuel-efficient than a 6-cylinder?
A four-cylinder engine does not require as much fuel as a six-cylinder, which requires half again as much fuel every time the pistons fire. A six-cylinder is more powerful, too, and accordingly uses more fuel. Four-cylinders are more economical, and if they are properly maintained, are more efficient.
How much more efficiency does a diesel engine got than a gasoline engine?
The diesel engine has more toque, gets better fuel mileage (30%) better, and will last longer with less maintenance. It does cost more initially and diesel fuel is more costly but for some applications is a wise choice.
How much oil to top up?
be more specific, make,model,engine size, fuel type,
In a car with a four-cycle engine why is it an advantage to have at least four cylinders?
it has more horsepower and does not waste as much fuel.
How much anti freeze does a 1997 Ford Ranger hold?
A little more information please ( size of engine , with or without air conditioning ) on your 1997 Ford Ranger
What the role of air displacement in engine?
It's just the complement to fuel displacement. How much air the engine takes in affects how much fuel it can burn.
How much power does a engine have in it?
Depends on engine size, how many cylinders, turbocharged or not, supercharged or not, fuel type used, etc. Please be more specific with the question.
How much gasoline does an average vehicle burn?
depends on cubic displacement and type of fuel being used some fuels have more stored energy. The larger the engine usually the more fuel consumed
What is the difference between a diesel engine and a petrol engine characteristic?
A diesel engine ignites it's fuel through compression and has no spark plugs. A gasoline engine has 1 or 2 spark plugs in each cylinder that fires at a set time and ignites the fuel. A diesel engine typically has much more torque than a gasoline engine and is designed to pull a heavy load. A gasoline engine will accelerate faster than a diesel but the diesel will have much more torque and be able to pull much heavier loads. A diesel engine will last much longer than a gasoline engine as it is built much heavier. Modern diesels are fairly quiet and make almost no more noise than a gas engine especially off idle.
What is the difference in bhp between petrol and diesel engines?
Both our internal combustion engines but the main difference is that a petrol engine uses spark plugs to ignite the fuel but a diesel engine has no spark plugs but instead uses compression to ignite the fuel. A diesel engine is also built much stronger than a gasoline/petrol engine. Diesel engines get better fuel mileage, last longer, and have much more torque or pulling power than a petrol engine. The only disadvantage to a diesel is the fact that it is more costly to build than a gasoline engine.
