Enhancing the process of diesel engine condition monitoring
- Liberty Technologies, Inc., Calgary, Alberta (Canada). Beta Products Div.
Condition monitoring technology for diesel engines has advanced at a rapid pace in recent years. Diesel engine manufacturers and third-party vendors have developed techniques that make it possible to determine the mechanical condition and performance of operating diesel engines. Such systems apply microprocessor-based instrumentation and computer analysis software to quantify engine combustion characteristics, valve events, piston motion, cylinder and liner condition, as well as auxiliary equipment such as turbochargers, pumps and motors. Non-intrusive measurement techniques provide time-domain, frequency-domain and process related data that are used to infer existing or impending problems and detect deviations from normal or achievable performance. A challenge industry faces is how to use the large amounts of data being produced by these programs to maximize the availability, reliability and ultimately, the economic performance of their equipment. This paper discusses methods for enhancing the analysis process to advance a diesel engine condition monitoring program. The physical aspects of combustion characteristics of compression-ignition engines are crucial performance indicators and are covered in depth using actual cylinder pressure and vibration signatures. Sophisticated analysis techniques and data-reduction schemes produce normalized measures that are trendable and can automate the analysis process. Case studies provided by Commonwealth Edison Company are used to illustrate the benefits of employing a state-of-the-art condition monitoring program. The paper will also illustrate how such programs are used to detect specific failure modes and recognize strategies for improving the overall performance of diesel engines.
