Bosch, Scaina CR Scania Coil Adjustment Shim - 077-133

Scania Common Rail (CR) Coil Adjustment Shim is a critical calibration component used in Bosch diesel injectors, designed to maintain injection pressure stability under high pressure and enhance the precision of the fuel system. By precisely adjusting the amount of fuel injected across almost the entire operating range with micron-level accuracy, it ensures stable engine operation at all RPM levels, contributes to maximizing performance, and helps optimize emission levels. Specifically developed for Bosch injection technologies, this high-precision component serves as a standard part of Bosch common rail systems. Exclusively used in Scania heavy-duty truck engines, this specialized component stands out with its superior surface quality, high wear resistance, and excellent fatigue strength. Manufactured with high dimensional precision through an advanced lapping process, it meets strict tolerance requirements.
