An On-Line Pressure Monitor for EFI-Control-Unit Test Diagnostics

Main aspects concerning the development of a burner-assisted ceramic particulate trap for diesel engines equipping urban buses have been examined. First of all the basic phenomena causing particulate accumulation inside the filter and chemical and physical parameters controlling regeneration have been studied. Then systematic measurements were performed in different running conditions on an urban bus equipped with a ceramic filter using a diesel fuel burner to start regeneration in order to verify the theoretical approach. These tests showed that: (1) The amount of particulate collected by the trap is a function of the different flat and/or hilly circuits inside the city; (2) regeneration has to be started with a proper amount of particulate collected (too little does not allow complete regeneration, too much is dangerous for trap life). Therefore an on-line continuous monitoring system of the particulate collected has been developed. When a certain level is exceeded, the filter is bypassed and regeneration starts. The system is based on the direct measurement of the exhaust flow by means of a Venturi and the pressure loss on the trap. The amount of particulate is defined by real time comparison of Venturi differential pressure and filter pressure loss. Urban buses were purposely designed in order to be equipped with a ceramic particulate trap plus the control unit. Tests of the system have been successfully performed on the buses operated on flat and hilly circuits inside the city.

Measurement And Control

Based on open NC system architecture, embedded condition monitoring and diagnosis units were studied with the characteristics of modularization and reconfigurable. The intelligent measurement and control unit can be used to on-line monitoring, fault early warming, intelligent diagnosis and remote maintenance, it provied a solution for group integration monitoring system construction of high-grade NC machine. In this paper, the implementation and function of the intelligent measurement and control unit were introduced from 4 aspects including whole framework, hardware, software and XPE OS. An example of cutting force on-line monitoring were given, which operate well for alarming in unstable cutting condition.

Channel Filter

DF10 filter rod forming machine produced by Italy GD Automatic Machinery Ltd is the world's fastest filter rod maker adopting the design of dual-channel. To achieve automatic sampling detection on line, a PLC-based automatic separate channel filter rod sampling detection system has been designed. Mainly composed of a sampling and launching device, matching tube, receiving device, a test instruments, PLC control unit and data terminal, the system first samples the filter rods from the two channels, then launches them into the test instrument to measure their physical parameters, and after wards send the real-time feedback of testing data to the data terminal. The application results show that the system has the advantages of convenient operation, high stability, safety and reliability. With an effective batch’s completion rate above 98%, it greatly reduces the labor intensity of operators and QC personnel, and significantly improves the quality control capacity of filter rod production.
