| Abstract:
This invention is particularly concerned with the ignition of the explosive charge in internal-combustion or explosive engines, and has for its object to provide an improved igniter which shall retain the heat sufficiently to ignite a charge at the beginning of every cycle of the engine, although the character of the explosive mixture may vary and although the walls of the explosion-chamber are kept at a temperature sufficiently low to avoid premature ignition of the charge, even under high compression.
A further object is to provide an igniter, which will not become filled with carbon and will itself give long service.
Claims:
1. In an explosive-engine, the combination with a tubular extension or shell extended rearwardly from the cylinder-head, of an independent, tubular igniting ignition-tube, open at its forward end only, placed loosely within said shell or extension, substantially as described.
2. In an explosive-engine, the combination with a tubular extension or shell, extended rearwardly from the cylinder-head, of an independent, tubular igniting ignition-tube having a relatively large bore with a restricted port at its forward end, placed loosely within said shell or extension, substantially as described.
3. In an explosive-engine, the combination with a tubular extension or shell, extended rearwardly from the cylinder-head, of an independent, tubular igniting ignition-tube, open at its forward end only, placed loosely within said shell or extension, and a bushing secured in the forward end of the bore of said shell and independent of said ignition-tube, substantially as described.
a. In an explosive-engine, the combination with a dash-plate secured to the cylinder-head, a tubular extension or shell extended rearwardly from the cylinder-head and means to discharge oil upon said dash-plate, of an independent tubular igniting ignition-tube, open at its forward end only, placed within said shell or extension, substantially as described.
