Description: |
| Abstract:
My invention relates to that class of explosive-engines or internal-combustion engines in which a piston or other abutment is exposed in an abutment-chamber or cylinder to the impulse of the suddenly-expanded fuel, usually gas or a mixture of combustible vapor with air ignited within the clearance-space or combustion-chamber of the engine and the primary object of my invention is to increase the area of the piston or abutment exposed to the expansive force of the explosion over engines having a piston-stroke of the same length without thereby necessarily increasing the volume of the charge, or, in other words, without increasing the clearance-space in which the charge is compressed, thus exposing to the explosion the maximum piston area, while avoiding the objection of having to force such area against the new charge at the return stroke in the act of compressing it or having to draw in a fresh charge equal to the volume of the entire piston-stroke.
Claim:
An explosive-engine having in combination two abutments both of which are exposed to and move under the same impulse and one of which is movable independently of the other and means for holding one of said abutments stationary while the other moves. |
