COMPRESSION STROKE Meaning and
Definition
-
The term "compression stroke" refers to a specific phase within the cycle of an internal combustion engine. It is a step in the four-stroke engine cycle, which also includes the intake stroke, power stroke, and exhaust stroke.
During the compression stroke, the piston within the engine moves upward, compressing the air-fuel mixture within the combustion chamber. As the piston ascends, the valves in the cylinder head are closed, trapping the mixture inside. This upward movement of the piston reduces the volume of the combustion chamber, resulting in the compression of the air and fuel. The compression stroke occurs after the intake stroke, during which the air-fuel mixture was drawn into the cylinder.
The compression stroke is a crucial stage in the engine cycle as it lays the groundwork for the subsequent power stroke. By compressing the air-fuel mixture, the pressure and temperature within the cylinder increase, creating the conditions necessary for combustion to occur. Once the piston reaches the top of its stroke, the spark plug ignites the compressed mixture, leading to the power stroke.
Efficient compression during this stroke is key for the engine's performance, as it affects factors like power output, fuel consumption, and overall engine efficiency. Compression ratios, defined as the ratio of the cylinder's volume at bottom dead center to top dead center, play a crucial role in engine design and can vary depending on the specific application and desired engine performance.

Etymology of COMPRESSION STROKE
The word "compression" comes from the Latin term "compressio", which means "a pressing together" or "compression". It is derived from the verb "comprimere", which combines the prefix "com-" (meaning "together") and the root "primere" (meaning "to press").
The word "stroke" is derived from the Old English word "strāc", which means "a movement or a blow". It has Indo-European origins and is related to the German word "Strich" and the Latin word "strigilis".
When combined, the term "compression stroke" refers to the upward movement of the piston within an engine cylinder, where the air-fuel mixture is compressed before being ignited. This term is commonly used in the field of internal combustion engines to describe the specific phase or stroke in the four-stroke engine cycle.
