ABSTRACT:
A running quality evaluator for an internal combustion engine for optimizing the running quality of the engine. The running quality evaluator includes an engine speed circuit which conditions a series of trigger pulses from the engine. The conditioned trigger pulses from the engine speed circuit are converted by an integrating circuit into an engine speed signal. The engine speed signal increases as the frequency of the trigger pulses from the internal combustion engine increase. Thus, the engine speed signal changes as the frequency of the trigger pulses from the engine change. The engine speed signal from the integrating circuit is then converted into an engine quality signal by a differentiating circuit. The engine quality signal increases as the rate of change of the engine speed signal increases. The engine quality signal from the differentiating circuit is then integrated into an output signal by an output circuit. The output signal increases as the rate and magnitude of the engine quality signal increases. The output signal is visually displayed by a visual output device, such that an increasing value of the output signal is indicative of deteriorating engine quality performance. To increase engine performance, a user or technician can adjust engine operating parameters, such as spark timing, to minimize the output signal displayed by the visual output device.
