label: Description
content: The gas engine described is designed to effect a gradual combustion of the charge by the use of a weak mixture in the cylinder. In order that the mixture would not ignite too slowly a strong or explosive mixture was introduced into a separate but connecting chamber and ignited in the conventional way. The flame issuing with some force from the chamber into the cylinder effected a sufficiently rapid ignition of the weak charge.
label: Description
content: The inventors also describe a means of raining the pressure on the cavity of the slide valve carrying the burning ignition charge in a flame ignition engine, high enough to equal the compression pressure within the cylinder of the engine.
