In an internal combustion engine the gas vapor air mixture enters the cylinder during the stroke?
Intake
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
Difference between air standard and actual cycle?
The air standard is and estimate and is usually greater than the actual cycle due to various losses that occur during the actual engine operation.
Why volume of gas decreases on increasing pressure on it at constant temperature?
It is possible to explain this mathematically in terms of the Ideal Gas Laws, however, it should also be intuitively obvious that this is what would happen; when you press on a flexible substance, it compresses. This is equivalent to asking, why is it that when you push on a spring, you can make it shorter. Force moves things. How do you put pressure on a gas? You put it in a cylinder (such as the cylinder in an internal combustion engine) with a movable piston, and then you push the piston downward. Obviously, squeezing the gas will decrease its volume in the cylinder. The point about the constant temperature is that if you do this but the gas heats up, then the gas is going to push back. Again, this is what we see in an internal combustion engine. You compress the gas, but then there is fuel burned inside the cylinder, the gas gets very hot, and the piston is forced upward with considerable strength. So the engine runs.
Why are metal fins made as a part of the cylinder?
it is covering outside the cylinder of an engine. it is added to the cylinder head and walls in order to increase the surface area that can radiate the heat to the air pgassing by.
During what stage of engine operation does the piston move upward in the cylinder and force the burned gases out of the cylinder?
Exhaust stroke.
In a external combustion engine the fuel is burned inside the cylinder?
no.. by definition the combustion is outside of the engine. a steam engine would be an example.
Identify the source of thermal energy in an internal combustion engine?
In an internal combustion engine fuel is burned in a combustion chamber or cylinder inside the engine
In a gasoline engine the area the cylinder head where the air -and - fuel mixture is burned is called the?
Combustion chamber
In a gasoline engine the area in the cylinder head where the air and fuel mixture is burned is call the?
the answer is b cylinder just took the test its not the combustion chamber
During which stage of engine operation does the burning mixture of air and fuel force the piston downward?
This is during "combustion" which is the "power" stage of the operation.
Burned valve symptoms?
Engine miss, poor fuel economy, loss of power, and low compression on the cylinder with the burnt valve.
How is engine vacuum created?
During the intake stroke of each cylinder.
During engine operation the total distance that a valve opens is called the?
Lift
During engine operation the total distance a valve opens is called the?
Lift
What does it mean when only 5 out of 6 cylinders fire?
It means that the engine is "missing." With the engine running, pull the injecter wires on each cylinder. If the engine changes pitch or runs worse, go to another cylinder. If there's no change, then you've found the bad cylinder. Check the plug for fowling, the injector for operation, and finally try a compression test on the affected cylinder.
Why an engine having 4 nos valves is considered a better performer than a 2 valved engine?
the engine with 4 valves per cylinder can get the air/fuel mixture and the burned exhaust in and out more efficiently
