What direction is the piston going during the compression?
Using directions like upwards in this context is meaningless because you haven't defined how the piston is oriented.During the compression stroke of a typical 4-stroke gasoline engine, the piston takes energy from the crankshaft. The reason the whole scheme still works is that you get a lot more energy back after the combustion during the power stroke. Add up the total energy moved between the piston and the crankshaft over a whole cycle (two rotations of the crankshaft), and you will find the total being positive from piston to crankshaft.
How do you determine the compression stroke on a 350 Chevy engine?
Remove all the spark plugs and turn the engine over by hand. Place your thumb over the #1 plug hole and you will feel the pressure on the compression stroke. A compression gage will also tell you when you are on the compression stroke.
What happens in the cylinder during each stage of the 4- stroke cycle in an internal combustion engine?
Its as simple as 'Suck, Squeeze, Bang, Blow'. 1st stroke Down = vacuum draws in air and fuel from carb (suck) 2nd stroke UP = Compression of air and fuel (Squeeze) 3rd stroke Down = Mixture of air and fuel explodes pushing cylinder down. (Bang) 4th stroke Up = Kinetic movement of piston and crank shaft keeps moving pushing the cylinder back up and expelling the burnt air and fuel mixture. (blow) back to 1st stroke again. when most engines have 4 pistons all doing this at slightly different times the Bank stoke gives more than the force required to compress another cylinders contents.
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
Why petrol engines called constant volume engines?
In a engine, well 99.9% of them the piston is conected to a crank via a conrod, as nothing changes during the strokes of the piston and the cylinder bores dont change. The swept volume of the stroke is always constant.
What happens during each of the four strokes in the cycle of an internal-combustion engine?
1) When the Piston travels down during the first stroke its called the "Suction stroke"as it sucks in Air. 2) Then the Piston travels upward during the Second Stroke which is known as "Compression Stroke" as it compresses the air of the first stroke. Because of the compression the temperature increases. 3. Just before the Piston reach the top the injector sprays fuel and the high temperature mixture burns and expands and the Piston again goes downwards due to pressure and volume. 4. As the Piston travels upward in the 4th stroke the exhaust valves open and the burnt exhaust goes out. So the 4th stroke is the exhaust stroke. Shailesh Mehta
What causes no compression in a 2 stroke dirt bike?
No compression could be various things from your piston to your crank start with your piston by doing a compression test
Which type of the engine brake uses the compression stroke of the piston as its retarding stroke?
You're talking about an engine compression brake, commonly referred to as a Jake Brake.

What is the compression ratio for an engine?
It is the volume of the cylinder/combustion chamber/head gasket/piston volume(dish/dome) when the piston is at the bottom of the stroke divided by the volume when it is at the top of the stroke.
Compression ratio of the internal combustion engine is defined as?
The compression ratio of an internal-combustion engine, or an IC engine as it is more commonly called, is the ratio of the volume the highest capacity of the combustion chamber to its lowest capacity. In the IC engine, the piston makes a stroke, resulting in the compression of the air in the combustion chamber - the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke, is the compression ratio.
Differences between 2 stroke and 4 stroke engines?
Two strokes have two cycles the piston go through intake/compression and ignition/exhaust where four strokes have four separate piston cycles intake compression ignition and exhaust.
Where is the compression stroke located on a 1997 dodge ram 2500?
The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.
What is wrong with a 86 Honda when there is no compression in the motor?
Bad compression is usually worn out piston rings, no compression is usually bad valves - assuming it's a 4-stroke.
How fuel works in cars engine?
All gasoline engines are four-stroke designs. An engine has an intake stroke where the intake valve is open and the piston is moving downward, creating a vacuum that sucks the fuel into the cylinder. The next stroke is the compression stroke. The intake valve closes, and the piston begins to move upward and compresses the fuel in preparation for ignition. The third stroke is the power stroke. The piston is approaches the top of the cylinder in the compression stroke. Just before it gets to top dead center, the spark plug fires and ignites the fuel. The fuel rapidly expands and pushes the piston down with great force. The last stroke is the exhaust stroke. In this stroke, the piston completes the power stroke and begins to rise again. At this point the exhaust valve opens, and the piston forces the exhaust out of the cylinder in preparation for the intake stroke.
What term is used to describe the distance the piston travels from TDC to bdc when calculating compression ratio?
stroke
At what position is top dead center on a crate 350?
the piston in cylinder #1 at the top on the compression stroke
