Abstract
An engine analyzer for an internal combustion engine converts an engine waveform into a digital waveform which is displayed on a monitor. The waveform is converted using two analog-to-digital (A/D) conversion channels. A dedicated A/D control microprocessor is used to control the flow of the digital waveform data between the analog-to-digital conversion channels and a main computer. Waveform data transfer to the main computer is over a dedicated, high speed data bus. A peripheral control microprocessor is used to monitor other engine parameters and shares memory with the A/D control microprocessor.
