Bosch Common Rail Volkswagen Unit Injector Shim

Bosch CR Volkswagen Unit Injector Shim - 077-132

Volkswagen Common Rail (CR) Unit Injector Idle Adjustment Shim is a critical calibration component used in Bosch diesel unit injectors, designed to maintain injection pressure stability under high pressure and enhance the overall precision of the system. By precisely adjusting the amount of fuel injected at idle speed with micron-level accuracy, it supports stable engine operation across the entire RPM range, contributes to maximizing performance, and helps optimize emission levels. Specifically developed for Bosch unit injection technologies, this high-precision component serves as a standard part of Bosch common rail systems. Featuring superior surface quality and excellent wear and fatigue resistance, the idle adjustment shim is manufactured with high dimensional accuracy through an advanced lapping process to meet strict tolerance requirements.
