No, in fact the cooler the air is the better. Like all gases when air is heated it expands and when it is cooled it retracts, so the cooler the air is the more your engine will be able to suck in therefore creating more power, this is why turbocharged engines usually have an intercooler on them.
An intercooler is used to cool the hot, compressed air coming from the turbocharger or supercharger before it enters the engine. This cooler air is denser and contains more oxygen, resulting in more efficient combustion and increased engine performance.
You will get less power and worse fuel economy. It will also rise engine temperature slightly. Warm air is less dense than cold which means lower compression = lower horsepower.
Air Conditioning is a unit connected to the engine... when ac on, it connects to power from the engine to make it operate... it uses power making the engine work harder, consuming more gas. I've heard from research that driving less that 50mph(or 40 i think) with windows down is more fuel efficient.. while driving 40 or 50mph + and having the ac on is more fuel efficient.. because of drag from wind.
Engines can become more efficient by refining the processes that operate the engine, better fuel/air mixtures, better power transfer, alternate fuels
The compressor increases the pressure of the incoming air by compressing it, which allows more air to be packed into the combustion chamber. This increased air pressure helps create a more efficient combustion process, which leads to more power being produced in the engine.
A Jet engine contains a series of turbines that accelerate the air that enters the engine. As the air is accelerated it is compressed to a higher density at which point the fuel is able to begin combustion at ambient temperatures. As the engine warms it becomes more efficient as the fuel is pee heated and the compressor is able to spool faster. At higher altitudes the engine becomes more efficient as the initial air density is lowered causing less resistance on the turbines to accelerate the air, thus allowing a higher spool rate with less fuel. Jet engines are very inefficient at sea level when compared to their efficiency at cruising altitudes.
Gills are more efficient at obtaining oxygen, but there is much more oxygen in air to breath through the lungs.
To read more about energy efficient air conditioners, go to wikipedia and look up Energy star. This will give you information on how and why a unit will be more energy efficient and "green".
It doesn't, it helps cool the engine by running coolant through it and letting it air cool. The better the radiator = the better the cooling, thus making the engine more efficient.
The device that mixes air and petrol for the internal combustion engine is the carburetor. It controls the air-fuel ratio to ensure efficient combustion in the engine.
For a gas engine, the accelerator opens a valve in the carburetor/intake manifold, which allows more air into the engine. With more air, the carb/injector will deliver more fuel. WIth more air and fuel going into the engine, the engine will make more power.
Replacing the air filter with more efficient one and removing the air filter snorkel. Replacing the stock muffler with more efficient one. Re-jetting the carburetor .
