US 7,347,174 B2 · Combustion promoting device for internal combustion engine

Abstract

Disclosed is a combustion promoting device for an internal combustion engine which derives high combustion efficiency and high power from the internal combustion engine. The combustion promoting device is provided with a combustion promotion inductor formed of a super alloy having excellent heat resistance and thermal conductivity. The combustion promotion inductor is adapted to absorb high-temperature heat generated when an explosion stroke takes place. This absorption of the high-temperature heat allows the combustion promotion inductor to be maintained in a pre-heated state at all times, thereby serving as a kindler (a promoter generating a spark). As a result, the combustion promotion inductor rapidly increases the temperature of an air-fuel mixture introduced again after an exhaust stroke to reinforce the explosive force concomitant with the thermal expansion, thereby allowing the internal combustion engine to obtain high power.

Dependent claims

A combustion promoting device for an internal combustion engine, comprising:

an ignition plug for igniting an air-fuel mixture introduced into a combustion chamber of the internal combustion engine;
an electrode section provided with a ground electrode that is made of iridium (Ir) and is formed at a region protruding from one side of an upper end of the ignition plug, and a center electrode that is formed to be inclined from the center of the ignition plug toward the ground electrode so as to have a predetermined gap from the ground electrode, and for generating a spark;
and
a combustion promotion inductor including a horizontal section that is installed on one end of the ignition plug so as to be adjacent to the electrode section and is spaced apart from the electrode section by a predetermined interval, and a vertical section that is bent from the horizontal section and fixed to one end of the ignition plug, and made of a super alloy having excellent heat resistance and thermal conductivity.
