When air and fuel are compressed in an engine, the increase in pressure and temperature prepares the mixture for combustion. This compression promotes a more efficient and powerful explosion when the fuel is ignited, leading to improved engine performance. In internal combustion engines, this process is crucial for generating the energy needed to drive the pistons and ultimately power the vehicle. Proper compression also helps reduce emissions and increases fuel efficiency.

What happens to air when it sink?
When a parcel of air is forced downward, atmospheric pressure increases, causing the air to become compressed and therefore the temperature is also raised.
What is injected into the high pressure of air in a jet?
In a jet engine, fuel is injected into the high-pressure air that has been compressed by the engine's compressor stage. This fuel, typically aviation kerosene, mixes with the compressed air and is then ignited in the combustion chamber, creating high-temperature gases that expand rapidly. This expansion produces thrust, propelling the aircraft forward.
What is the purpose of the water seperator?
The purpose of a water separator is to remove water and other contaminants from fuel or compressed air systems. In fuel systems, it helps prevent water from entering engines, which can cause corrosion and damage. In compressed air systems, it ensures that moisture does not compromise equipment performance and reliability. Overall, water separators enhance efficiency and prolong the lifespan of machinery.
How does diesel charge air cooler work?
A diesel charge air cooler (CAC) functions by cooling the compressed air from the turbocharger before it enters the engine's combustion chamber. As air is compressed, its temperature rises, which can reduce engine efficiency and increase the risk of knocking. The CAC uses ambient air or coolant to absorb heat from the compressed air, lowering its temperature and increasing its density, thereby enhancing the engine's performance and fuel efficiency. This process ultimately helps in achieving better combustion and reducing emissions.
What is squeezed air called?
compressed air
What happens to air when it is compressed or allow to expand?
It cools, and when it is compressed, it warms
How fuel is burnt in engine?
Fuel is mixed with air, compressed then ignited.
What is the purpose of the spark plug?
It ignites the compressed air/fuel mixture.
What does a diesel engine use to ignite the fuel with since it doesn't use a spark plug?
The fuel/air mixture in the cylinder is compressed to the point where it gets hot enough to self ignite.The fuel/air mixture in the cylinder is compressed to the point where it gets hot enough to self ignite.
Why pump can't use for compressed air?
Pump cant use compressed air because its a heat exchange process where mostly burnt fuel is converted as a source of energy . Compressed air is best in compressor engines .
What happens to air when air compresses?
When air is compressed temperature increases because of the collission and vibration of molecules
Can compressed air fuel will give much efficiency than fuels?
probably not
What is an internal-combustion engine?
An internal combustion engine is an engine that uses air, fuel, and spark to create the power to move. A perfect air-fuel mixture is pulled into the cumbustion chamber, its compressed by the piston, and once its compressed the spark plug ignites the air-fuel mixture and the process is completed.
When air in the cylinder of a diesel engine is compressed it?
it gets hot, and ignites the diesel fuel that is injected by the fuel injectors.
What happens to air when it is adiabatically compressed?
When air is adiabatically compressed, its pressure and temperature increase while its volume decreases. This occurs without any heat exchange with the surroundings.
How do jets achieve motion?
Jets achieve forward motion through the thrust produced by their engines. The jet engines pull air in, then this air is compressed and fuel is mixed and burned along with the compressed air, and the turbine extracts energy from the air and fuel mixture, and this energy is forced out through the rear of the engine.
What happens in the upstroke of the piston in the crankcase in a four stoke engine?
On compression the air is compressed, and on exhaust it is forced out of the cylinder.On compression the air is compressed, and on exhaust it is forced out of the cylinder.
