IC engine performance measuring appts. - derives digital signal using inductive pick=up to measure power and speed of drive shaft
Реферат: An inductive pick-up generates impulses dependent on the speed of rotation of the drive shaft of an i.c. engine and feeds them to a pulse shaper. A speed lever selector is connected to the latter and feeds the control unit for the ignition and the control for the measuring unit. Both controls are synchronised with clock pulses from a clock pulse generator which also governs an normalised pulse train generator. A further pulse train generator is coupled to the control unit to generate an output corresponding to the pulse count from the motor during a given time interval. A subtraction circuit counts the difference between the two pulse trains and this value is recorded.
