ABSTRACT:
An apparatus, and a corresponding method, measures reciprocating engine performance based on torque output of the engine. This is accomplished by observing positional behavior of a rotating member driven by the engine. The apparatus includes a measurement device (129) that provides an acceleration signal (116) indicative of acceleration of the rotating member (101). A gated ACCEL-DECEL device (126) provides a gated acceleration signal (141 ), dependent on the acceleration signal (116) gated by an accumulate enable flag (138) corresponding to a first span (120) of rotary position of the rotating member (101 ). An accumulation device (143) accumulates the gated acceleration signal (141 ), and provides an accumulated result (149) dependent thereon. This accumulated result is a variable indicative of the reciprocating engine's performance.
