Packaging Very High Pressure Transducers for Common Rail Diesel Injection Systems

Diesel powered commercial engines dominate the surface transportation markets such as trucks, barges, ships, locomotives and public transport. Manufacturers of diesel engines and systems are increasing being pressured to offer more efficient fuel delivery systems with minimal pollution. Various high pressure direct diesel injection systems have been designed to atomize the fuel so that. it bum efficiently and emit very little pollution. The use of pressure transducers in closed loop with an Engine Control Unit (ECU), is on the increase to help achieve the goals for performance and pollution. These demanding applications are forcing pressure transducer manufacturers to include features in their products so that the device can operate in a hostile environment while maintaining a good price-performance ratio with excellent durability.
