Siemens Pizo Injector Shims

Product Introduction

Siemens pizo injector shims are thin, flat components used in the assembly and calibration of piezoelectric fuel injectors in diesel engines. These shims are part of the precision engineering process that ensures proper functioning and optimal performance of pizo injectors within a high-pressure common rail fuel injection system.

Function of Siemens Pizo Injector Shims:

Precision Calibration: Pizo injectors require precise calibration to ensure that the fuel injection process occurs at the correct timing and with the desired fuel volume. Shims play a role in achieving this precision by fine-tuning the injector’s internal components.

Adjusting Injector Flow Characteristics: Shims can be used to adjust the flow characteristics of the injector, such as controlling the rate and duration of fuel injection. This is essential for optimizing combustion efficiency and emissions control.

Compensation for Manufacturing Variations: During the manufacturing process, slight variations in dimensions can occur. Shims help compensate for these variations, ensuring that each injector meets the desired performance specifications.

Correcting Wear and Tear: Over time, wear and tear can affect the performance of injectors. Shims can be used to restore proper injector function by adjusting internal components to compensate for wear.
