Simplified Indicated Engine Performance Data Acquisition and Analysis Using LabVIEW

In-cylinder engine performance indicated by in-cylinder pressure data yields important information which can improve and quicken engine development. A data acquisition and analysis system has been developed with limited prior data acquisition knowledge using LabVIEW software to simplify the acquisition and analysis process. Separate programs were developed to record engine data and to analyze indicated performance. Up to one hundred consecutive cycles can be analyzed. Individual cycles are analyzed as well as the composite average cycle. This system provides information which greatly aids the search for maximum engine performance and extends this capability to developers and builders with limited research and engineering budgets and knowledge.
