IGNITION TIMING MEASUREMENT DISPLAY DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To easily monitor an ignition timing for an internal combustion engine while maintaining the internal combustion engine and an igniter so as to operate the internal combustion engine as needed. SOLUTION: This ignition timing measurement display device comprises: a reference speed signal pulse detector 2 for detecting reference speed signal pulses from the internal combustion engine 1 having a magnet A; and an ignition noise pulse detector 4 for detecting ignition noises of electromagnetic waves generated near an ignition plug 3 when igniting the internal combustion engine 1. The ignition timing with the magnet A is computed and displayed in accordance with the signal pulses and the ignition noise pulses. COPYRIGHT: (C)2007,JPO&INPIT
