Compression happens during which part of the sound wave?
it happens during the trough
During the stage of internal combustion engine operation in which the piston rises and compresses the fuel in the combustion chamber?
This is called the compression stage. During the four stroke sycle (Otto cycle) the four stokes are induction, compression, power and exhaust. Each piston does this in a set order to even out the stresses caused, and thereby smooth the output. For example the firing order (i.e. power stroke) on a four cylinder engine could be 1,3,4 and 2 or 1,2,4 and 3.
What is compression technology in pharmaceutical manufacturing?
Compression technology refers to the compression of tablets (pills) during the drug formulation or manufacturing process. Since the most common method of drug delivery is the oral solid dosage form, a great amount of research and time has been put into perfecting the compression technique. There have been recent innovations and advancements in compression equipment to minimize tablet weight variation.
How do compression load cells work?
Compression load cells work by measuring the force or load applied to them through compression. They contain a strain gauge sensor that detects changes in electrical resistance caused by the slight deformation of the load cell when subjected to pressure. This change in resistance is then converted into an electrical signal that can be calibrated and used to determine the applied load.
Can mater be created during a chemical reaction?
During a chemical reaction matter is neither created nor destroyed
What engine is the air and fuel mixture ignited by the heat created during the compression stage rather than a spark plug?
That's your average Diesel, or compression ignition engine.
In what type of engine is the air-and-fuel mixture ignited by the heat created during the compression stage rather than by a spark plug?
Diesel
AF mixture is compressed?
Yes, during the compression stroke.
What are the Names of each stroke for 4-stroke cycle?
As a kid I was always told: Suck-Squeeze-Bang-Blow!Induction, Compression, Expansion (or Ignition), ExhaustAs the piston is drawn down, the inlet valve opens and fuel mixture is drawn in with fresh air. (with turbo engines, it's pushed in)Piston rises and the inlet valve closes compressing the gasesAround tdc the mixture is ignited (spark - Petrol or by the heat caused during compression - Diesel) and the piston is forced down by the expanding (ignited) gasesPiston rises and the exhaust valve opens to allow the burnt mixture to be forced out.
How do fossil fuel create motion?
TRANSFORMATION of ENERGY - HEAT Energy to ROTATIONAL Energy.IN SHORT - Fossil fuels - like Petroleum Products produce Pressure and displaces PISTON when Ignited (Air and Fuel mixture) inside Mechanically Designed Engine during Compression Stroke.
What is the difference between regular fuel and dieselfuel?
Regular fuel, gasoline, is more flammable and is usually ignited by a spark plug. Diesel fuel is a "heavier" fraction of the crude oil and is usually compression ignited when used in a regular piston engine. This means that the engine first draws in air, then compresses this air quite a lot. During compression the air heats up to the point wherei it will ignite once ignited.
During an engines intake stage what passages inside the cylinder head must the incoming air and fuel mixture flow though in order to enter the cylinder?
Intake valve must be open to allow atomized fuel mixture to enter cylinder--than all valves are closed during compression stroke 4- stroke engine 1) intake valve open to allow fuel mixture to enter cylinder 2) compression stroke all valves closed 3) ignition stroke mixture is ignited by spark from spark plugs 4) exhaust stroke--exhaust valve is open to allow residue to escape
Why compression and combustion are always adiabatic process?
Adiabatic compression occurs when a precisely controlled mixture of a flammable gas and oxygen are ignited by the heat of colliding molecules during the compression of said gas. This causes an explosion and the explosion causes an expansion of the gasses. These expanding gasses must force their way out of confinement and pushes a piston. This turns tirns a crank shaft which will mechanically open and close intake and exhaust valves through push rods.
How does a diesel engine add fuel to the compress air and it is ignited?
Diesel engine doesn't have spark plug as like petrol engine . But It has an atomizer (A plug through which fuel is sprayed into the combustion chamber).... During Intake Stroke ,the vacuum caused by piston draws air (only) into the cylinder ,Now during Compression stroke Atomizer comes to play ,Spraying Diesel into the cylinder meanwhile the piston compresses the air, so that it's temperature rises to such extent that diesel could be ignited by the heated air, and there comes the power stroke and so on... So ,Conclusion is that Diesel Engine doesn't use spark plug, but the increase in temperature of air during compression is enough to ignited the diesel.. Hope You Got The Answer
During which stage of engine operation does the burning mixture of air and fuel force the pistons downward?
The power stroke * intake / compression / power / exhaust
What is 8.1 comresson mean for a car engine?
During the compression stroke the volume of air/fuel mixture is compressed 8 to 1 times just before ignition.
What is a compression ratio?
Compression Ratio is the ratio between the original volume and the compressed volume in combustion chamber. The compression ratio is denoted as CR. It is the measure of how much air-fuel mixture is compressed during the compression stroke in the case of the gasoline engine (in the case of the diesel engine only air is compressed. Compression ratio is found by dividing the volume of stroke of the cylinder (swept volume) and clearance volume when the piston is at BDC by the volume when the piston is at TDC (ie clearance volume). Compression ratio= (Swept volume + Clearance volume) / Clearance volume. For example engine has a Swept volume of 700 cc. It has clearance volume 50 cc. Compression ratio= (700 + 80) / 80 =9.75: 1 It means Air fuel mixture is compressed to 1/9.75 of its original volume during compression stroke.
