Diesel Systems
Electronic Diesel Control (EDC) is the engine management system for diesel engines. For mixture preparation and injection we have different electronically controlled systems: In-line pumps, distributor pumps, single-plunger pump systems such as Unit Injector System (UIS), and the Common Rail accumulator injection system.
The latest Common Rail System (CRS) generation has piezo inline injectors. The electronically-controlled piezo actuator permits switches five times as fast as a solenoid valve allowing an even more precise design of the rate-of-discharge curve.
