Since the invention of the engine until now the pursue for higher efficiency and clean process and methods to transform energy did not stop. In order to achieve this goal, it is necessary to control the synergy between the engine, the fuel and the fuel injection system; this last one is the responsible system component to bring and to burn the fuel into the combustion chamber of the engine. Even when there is a lot of success with the continuously developing and use of the electronic devices, the homogeneous air fuel mixture and the complete combustion remains as a target accomplished not yet. For at least the last twelve years during period of research and development of engines, fuels, fuel injection and exhaust after treatment systems a lot of efforts were focused on the reduction of the contaminant emissions, even when the problems of the uncomplete combustion are not solved and the causes of the contaminants are not well defined. Understanding the function and all the parameters of the fuel injection as part of a whole system which delivers energy allows to deliver the aimed clean energy. The DUAP fuel Injection systems are produced with focus on efficiency and quality to inject, to atomize and to burn the fuel, as well as in the flexibility to operate at different requirements of the engine load and with different type and qualities of fuel; looking in this direction, the conventional mechanical and the modern fuel injection systems like common rail including the piezo ceramic technologies, have still a lot of potential regarding the atomization and the distribution of the fuel into the entire combustion chamber. These two parameters determine the effectiveness of the fuel combustion and how optimized the clean-energy delivery will be. Hence a continuous improvement regarding the implementation of high performance materials and production-measuring and testing processes is requested. In other words, a reengineering of processes, embracing the technical, commercial and social aspects. The application of this reengineering in a systematic way, with order and method as well as engineering discipline, allowed to achieve new scales regarding fuel consumption and durability of the injection components. One example of this is the extraordinary 3.5% improved fuel combustion in a retrofitted engine with a conventional-mechanical injection system and over 9000 operating hours of a common rail injector. The DUAP's contribution to deliver clean energy with the effective combustion of the fuel is beside the flexibility of the injection system to function with different kind of fuels. Each one has a wide range of viscocities in different operation and environment conditions. The ability to understand the design and construction process to produce components with a robust and optimized design allows to fulfil the requirements and expectations of the manufacturer, customer, and operator. Delivering clean energy is a technical and a social matter, where man and machine are connected in fields and activities like economy, safety, reliability, efficiency and quality.
