cylinder ratio
1Cylinder head porting — refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve the quality and quantity of the air flow. Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing… …
2Cylinder head — A 302/5.0L Ford cylinder head In an internal combustion engine, the cylinder head (often informally abbreviated to just head) sits above the cylinders on top of the cylinder block. It closes in the top of the cylinder, forming the combustion… …
3Cylinder (engine) — Illustration of an engine cylinder with a cross section view of the piston, connecting rod, valves and spark plug. A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels. Multiple cylinders… …
4Cylinder stresses — Circumferential stress is a type of mechanical stress of a cylindrically shaped part as a result of internal or external pressure. The classic example of circumferential stress is the tension applied to the iron bands, or hoops, of a wooden… …
5ratio of expansion — the ratio of the volume of steam in an engine cylinder or turbine when the piston is at the end of the stroke to the volume at cut off …
6Cylinder circumference ratio — Соотношение диаметров цилиндров и опорных колец (при качении в печатной паре) …
7Compression ratio — For compression ratio in data compression, see data compression ratio. The compression ratio of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its… …
8Stroke ratio — In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term which is used to describe the ratio between the diameter of the cylinder bore and the length of the piston stroke within its… …
9Heat capacity ratio — The heat capacity ratio or adiabatic index or ratio of specific heats, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V). It is sometimes also known as the isentropic expansion factor and is… …
10compression ratio — Auto. the ratio of the cylinder volume enclosed by the piston at its outermost position to the volume enclosed by it at its innermost position. [1905 10] * * * Degree to which the fuel mixture in an internal combustion engine is compressed before …
