Self Study Program 352 – Unit Injectors with Piezo Valves

Self Study Program 352 – Unit Injectors with Piezo Valves Design and Function PDF. Low consumption and excellent performance have made the rise of the diesel engine  unstoppable. Nevertheless the targets for diesel engines in terms of emissions, driving comfort and engine  performance are also being raised constantly. Customer satisfaction, environmental protection and the fulfilment of legal requirements are always at the forefront and can only be achieved through continued development.

The introduction and ongoing development of unit injectors has created considerable  competitive advantages in the areas of injection pressure, injection precision and efficiency. In collaboration with  Siemens VDO Automotive AG, we have developed a unit injector with the same or even greater  advantages. It also allows new flexibility in the configuration of the pilot, main and secondary injection  phases. Improved mixture, higher efficiency and lower noise emissions are the innovative results.
