Design Of High Pressure Common Rail Diesel Engine Pressure Sensor

High pressure common rail diesel engine pressure sensor is a pressure detection unit for diesel engine Common Rail System, and the most important basis for the ECU to make the best fuel injection quantity. To achieve the most efficient fuel air mixture combustion ratio in the engine, also the energy saving can be attained most critical aspect. In this paper, " The design of high pressure common rail diesel engine pressure sensor" as its theme.From the overall structure and electrical design of the high-pressure rail pressure sensor, key technology research, performance validation and application case sharing parties face common rail sensor development discussed, determine the research content of the paper. The main work includes:1. Analysis of the current development situation of high pressure common rail diesel engine technology, discussed the key position of pressure sensor in high pressure common rail system. By comparing the domestic and foreign technology, leads need to focus on research and validation of the direction of the paper2. Discusses the overall framework consisting of common rail pressure sensor, program focuses on measuring sensor and signal processing programs. By the contrast, select the appropriate program design.3. On the basis program confirm of the high pressure common rail pressure sensor, focus on the mechanical structure, the packaging of sensitive components, electrical connection and EMC optimization design and other aspects of the details of research and process optimization, to establish a complete set of product design and production specifications.4. Through a series of reliability test, performance test of sensor. Through the calculation and analysis of experiment, Verify technical solutions and performance metrics that have reached a preset design goals, products with high pressure common rail system using standard.5. Finally share two successful product application cases, Certify that the above analysis and conclusions of the research is feasible and effective, Product performance has basically reached the expected use of indicators, and can be applied in practice.
