INTERNAL COMBUSTION ENGINE IGNITION TIMING MEASURING AND DISPLAYING APPARATUS

Title:

INTERNAL COMBUSTION ENGINE IGNITION TIMING MEASURING AND DISPLAYING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2006/109669

Kind Code:

A1

Abstract:

There are included a reference number-of-revolutions signal pulse detector (2) that detects signal pulses of a reference number of revolutions of an internal combustion engine (1) having a magnet (A); and an ignition noise pulse detector (4) that detects the ignition noise of electromagnetic waves occurring in the vicinity of an ignition plug (3) at the time of an ignition of the internal combustion engine (1). The timing of an ignition by the magnet (A) is calculated, based on the signal pulses and an ignition noise pulse, and displayed. Thus, the ignition timing of the internal combustion engine can be easily monitored. This allows the maintenances of the internal combustion engine and ignition apparatus for achieving a required operational performance of the internal combustion engine.
