Delphi Common Rail 2 Pin Idle Adjustment Shim

Delphi CR 2 Pin Idle Adjustment Shim - 077-111

Delphi Common Rail (CR) 2 pin idle adjustment shim is a critical adjustment component used in Delphi diesel injectors that operates with precision under high pressure and contributes to maintaining stable injection pressure. It ensures precise control of the amount of fuel injected at idle speed, significantly contributing to stable engine operation at low RPM, improved performance, and better emission values. This specific shim is used exclusively in heavy-duty (truck) engines and is a standard component in Delphi common rail systems. To meet the requirements of high surface quality, superior wear resistance, and measurement accuracy, it is manufactured with tight tolerances using a high-precision lapping process.
