Denso Common Rail Adjustment Shim

Denso CR Adjustment Shim - 077-110

The Denso common rail (CR) adjustment shim, used as an inner coil shim in Denso brand diesel injectors, is a critically important adjustment component that operates precisely under high pressure and contributes to maintaining stable injection pressure. By enabling the precise control of the fuel quantity injected by the injector, it significantly contributes to improving engine performance and optimizing emission values. This component is included as a standard part in almost all Denso diesel injectors. To meet the requirements of high surface quality, superior wear resistance, and measurement precision, it is manufactured with high accuracy using a lapping process.
