ABSTRACT:
An electronic measurement system for monitoring and measuring indicated horsepower (IHP) of piston type engines which may be spark-ignition, diesel, steam or other power type, based on two or more cycles of operation. Indicated horsepower (IHP) is computed for each engine cylinder in sequential fashion and is based on measurements of cylinder pressure and crankshaft angle of rotation versus time. The system hereof is also operable to measure revolutions per minute of the engine shaft, as well as combustion and compression pressures (just before ignition).
