A Comprehensive Data Generation Facility for Internal Combustion Engine Evaluation and Development 900166
A super-microcomputer is utilized in an engine-dynamometer facility to create a comprehensive engine evaluation system. A unique feature of this system is the combination of experimental and modelling activities in evaluating engine designs. The system acquires engine operating conditions, emissions, and dynamic cylinder and manifold pressures via the data acquisition interface. After acquisition, the computer is also capable of providing engine model predictions from either an empirical model or a zero-dimensional thermodynamic model. The data gathering process is speed limited by the settling time of the engine-dynamometer system.
The acquisition and modelling procedures are controlled by an internally developed, menu driven, software package. Features of the system include commercial relational database software for rapid storage and retrieval of acquired data and a high resolution graphics monitor for immediate display of analyzed pressure data. Data integrity checks performed before storage insure data quality.
This paper describes the test cell, the instrumentation, the acquisition procedures, the analysis and display procedures, and the database organization and storage. The modelling procedures are deferred to a future report. The system is currently being used for the evaluation and comparison of various combustion system design features.
