What is the Role of Adjusting Shims in Common Rail Injectors?

Q: Can you explain the function of adjusting shims in common rail injectors and how crucial they are?

A:

Adjusting shims are thin, precision spacers used to set the injector's opening pressure. This is a critical calibration step. An incorrect shim size will cause the injector to open at the wrong pressure, leading to poor fuel atomization, unbalanced cylinder performance, increased emissions, and reduced power.

For rebuilders and large fleets in Eastern Asia and Southeast Asia, maintaining a comprehensive inventory of these small but vital parts is a logistical challenge. The pain point is the need for a supplier who can provide a full range of sizes with consistent thickness and material quality, ensuring every rebuilt injector meets specification.

Point Power Tech (Wuzi) Co., Ltd. produces adjusting shims with laser-cut precision from high-grade spring steel. We guarantee consistent thickness and flatness, which is essential for accurate pressure setting. We offer shims in complete sets, covering a wide range of applications, making it easier for our clients in Asia and beyond to manage their inventory and streamline their rebuilding processes.

Don't let a small shim cause a big problem. Rely on Point Power Tech for precision that powers performance.
