A combustion promotion device for a diesel internal combustion engine is provided to reduce nose and improve fuel efficiency by absorbing high temperature heat instantaneously generated during explosion of the diesel internal combustion engine and dissipating heat to the outside. A combustion promotion device for a diesel internal combustion engine, includes a piston(300) and a combustion promotion derivative(200c). The piston compresses air-fuel mixture introduced into a combustion chamber of the diesel internal combustion engine. The combustion promotion derivative includes a ring-shaped main body(252) arranged on the piston, and support legs(254) protruded from an outer surface of the main body and fixed on the piston. The combustion promotion derivative is made of heat-resistant alloy selected from a group consisting of nickel steel, chrome steel, nickel-chrome steel, platinum steel, iridium steel, and osmium steel. |
