IGNITION DEVICE: abstract simplified (18156488)

• This abstract for appeared for patent application number 18156488 Titled 'IGNITION DEVICE'

Simplified Explanation

This abstract describes an ignition device for a spark ignition-type internal combustion engine. The device aims to prevent a phenomenon called creeping discharge, which can occur when the air-fuel mixture in the combustion chamber reaches high pressure. The ignition device includes an ignition plug with a high-voltage side electrode and a ground side electrode. It also includes a high voltage generation device that applies voltage to the high-voltage side electrode, and an extension device that prolongs the time it takes for the voltage between the high-voltage side electrode and the ground side electrode to reach a dielectric breakdown voltage. This ignition device helps improve the efficiency of the internal combustion engine.

Original Abstract Submitted

An object herein is to provide, with respect to a spark ignition-type internal combustion engine in which the pressure of the air-fuel mixture in the combustion chamber becomes high, an ignition device which can suppress occurrence of a creeping discharge and thus contributes to highly efficient operation of the internal combustion engine. The ignition device according to this application includes: an ignition plug having a high-voltage side electrode and a ground side electrode; a high voltage generation device that applies a voltage to the high-voltage side electrode of the ignition plug; and an extension device that extends a dielectric breakdown-reaching time period that is a time period from when the voltage is applied to the high-voltage side electrode of the ignition plug, to when a voltage between the high-voltage side electrode and the ground side electrode of the ignition plug reaches a dielectric breakdown voltage.
