1 Inch Nozzle Nylon Holder

There is a nozzle-and-holder assembly fitted in the cylinder head for each engine cylinder (Fig. 1). These components form an important part of the fuel-injection system and help to shape engine performance, exhaust emissions and noise characteristics. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.
