During the compression stroke in an engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the gases, making them more volatile and ready for combustion when the spark plug ignites the mixture.
During the compression stroke in an internal combustion engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the mixture, preparing it for ignition.
A piston changes direction twice during one complete diesel cycle – once during the compression stroke and once during the power stroke.
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.
You know you are on a compression stroke in an engine when the piston is moving upwards, compressing the air-fuel mixture within the combustion chamber. This is typically indicated by the intake and exhaust valves being closed during this stroke.
The stage that occurs just before ignition in an internal combustion engine is the compression stroke. During this stage, the piston moves upward in the cylinder, compressing the air-fuel mixture, preparing it for combustion when the spark plug ignites the mixture.

During a compression stroke in an internal combustion engine, the piston moves upward in the cylinder, compressing the air-fuel mixture. As the piston ascends, the intake valves close, creating a high-pressure environment. This compression raises the temperature of the mixture, making it more volatile and ready for ignition. At the end of the stroke, a spark plug ignites the compressed mixture, initiating the power stroke.
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

No compression could be various things from your piston to your crank start with your piston by doing a compression test

You're talking about an engine compression brake, commonly referred to as a Jake Brake.
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.
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.
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.
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.
