Which stage occurs just before ignition in an internal combustion engine?
Compression Stroke
What percent of its original volume can air be compressed to?
Standard air can be compressed until it becomes a liquid according to the Ideal Gas Law. The density of liquid air is about 870 kilograms per cubic meter, and so theoretically you could get the compressed air down to this before it transitions to a liquid. Also, if the air were thrown into a black hole, or there is enough air to create a black hole, then theoretically the mass would be concentrated at a point in the center and have a volume of zero.
What was used before the internal combustion engine?
Steam engines however these were used in heavy cumbersome vehicles when they were used in transport. however factory's generally got their power from steam.
You can boil water in a paper cup over a direct flame without burning it How can you explain that?
This is only how i explained it to myself after i did the experiment, so it might not be right. Burning is the result of a combustion reaction, and combustion reactions require a certain amount of activation energy to start. When the paper is in contact with water, the energy from the open flame that would usually start the combustion reaction is transferred to the water before the paper can ignite. This raises the temperature of the water and it will eventually reach boiling point. Now when all the water has evaporated, then the cup burns because there is nowhere left for the heat to be transferred to.
Why is compressed air at a high pressure?
Compressed means that you've taken something that is at one size, and then forced all of it into a smaller size. The only way to get the same amount of stuff that was in a bigger space into a smaller space is by packing it tighter. And when you pack something tighter each part will push against the neighboring parts harder than they did before. And when parts starts to push more against other parts that means that the pressure goes up.
What is preignition of fuel?
Pre-ignition of fuel that occurs in a spark-ignition engine is when the air/fuel mixture in the cylinder ignites before the spark plug actually fires. It can be initiated from a hot spot such as in the combustion chamber.

How Combustion lag and ignition timing are connected?
Combustion lag refers to the time between spark(ignition) and the highest combustion pressure in an engine. Ignition timing refers to how many degrees before top dead center(top dead center compression in 4 strokes) the crankshaft rotation is during ignition. These two are connected by timing your ignition on point with combustion lag characteristics to tune ignition timing and gain max volumetric efficiency out of an engine. Timing advances (ignites farther from tdc) as rpm's increase.
Why is carburetor used in petrol engine but not in diesel engine?
a petrol engine needs to mix its air and fuel before passing it into the combustion chamber before being ignited diesel has its air mixture heated as the piston compresses it in the combustion chamber then the atomized diesel fuel is injected into the hot air and is ignited.
Can fuel stabilizer cause smoke from tailpipe its white didnt notice it before?
No. White smoke is a symptom of coolant entering the combustion chamber. Stop driving the car and have it looked at by a professional. Serious engine damage will occur if it is indeed coolant in the combustion chamber and you continue to run the engine.
Discuss detonation in SI Engine?
It high pitch metallic ringing sound created due to automatic ignition of the " end- gas" (Air-Fuel mixture present farthest away from spark plug) before the main flame front reaches the end of combustion chamber. by UMMID
How do you change the spark plugs on a 2004 dodge durango 4.7?
# Remove necessary air filter tubing at throttle body. # Prior to removing ignition coil, spray compressed air around coil base at cylinder head. # Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber. # Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. Also check condition of ignition coil o-ring and replace as necessary. # Inspect spark plug condition.. # Start the spark plug into the cylinder head by hand to avoid cross threading. # Tighten spark plugs.. # Before installing ignition coil(s), check condition of coil o-ring and replace as necessary. To aid in coil installation, apply silicone to coil o-ring. # Install ignition coil
Glowing hot spots in the combution chamber that ignite the fuel before timed ignition is called?
pre-ignition or inaccuratley, Dieselling. it is , of course a hazard, and could cause a backfire, or even an engine explosion.
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 VVT - you?
its were a combustion engine has valves being open or closed for different amouts of time at different rpm. it stands for Variable Valve Timing. sometimes engines get choked of air or lose fuel and air from the combustion chamber before it is burnt so VVT fixes this
