ABSTRACT:
The full-power condition of an internal combustion diesel engine is tested by an acceleration burst test in which the engine initially operated at idle speed is suddenly given full throttle and caused to accelerate to a maximum governed speed. A tachometer means coupled to the engine produces one electrical pulse per engine cycle. The time taken in going between a predetermined low speed and a predetermined high speed is accurately determined, despite irregularities in the engine, by adding a portion determined by interpolation in the time period between pulses at the low speed, and a portion determined by interpolation in the time period between pulses at the high speed, to the intermediate time periods.
