Abstract
Caterpillar Inc. has developed a new diesel engine fuel system, powered by hydraulics and controlled electronically. This Hydraulic Electronic Unit Injector (HEUI) requires no mechanical actuating or mechanical control devices. HEUI offers many advantages over conventional diesel engine fuel injection systems.
The HEUI design and development process focused on providing a product which meets the customers' needs for a reliable, cost effective fuel injection system with performance characteristics enabling the engine to meet future stringent emissions and noise regulations. This paper describes some of the unique hydraulic and structural analysis tools and techniques, and the integration of the design, analysis, test, and manufacturing processes used in the development of the HEUI product.
