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 intake manifold pressure and the engine speed. A turbocharger of the engine includes a turbine that is driven by the engine exhaust and a compressor that delivers air to the intake manifold. The performance of the turbocharger is tested by stabilizing the engine and the turbocharger at no-load, low-idle speed, quickly accelerating the engine to maximum governed speed, and determining how the turbocharger stabilizes after the engine stabilizes at the maximum speed.
