An ignition device for an air-compressing internal combustion engine of the type having an injection nozzle arranged in a cylinder head, said ignition device including an elongated heating element, a hollow casing having a cylindrical wall spaced from and surrounding a substantial part of the length of said element, thereby providing open space therebetween, said element being spaced radially inward from said cylindrical wall, a heat reservoir in the form of at least one incandescent body operatively disposed between said cylindrical wall of said casing and said heating element and occupying a minor part of said open space and an inlet opening in said cylindrical wall of said casing through which fuel enters into the hollow interior of said casing where it ignites and burns upon contact with said incandescent body.
