ABSTRACT:
This disclosure relates to a system for analyzing the performance of a reciprocating piston, internal combustion engine such as a diesel engine. Sensors are connected to the engine, which respond to various operating parameters, and signals representing the parameters are fed to computer processing equipment. Two of the parameters are the lubricant system pressure and the engine speed. To test the lubricant system, the engine speed is stabilized at maximum governed speed and then the fuel supply to the engine is quickly cut off. The lubricant system pressure and the engine speed data are sensed and processed as the engine decelerates, the processing including a comparison of the pressure-speed characteristic with a standard or reference characteristic.
