초록

Combustion engines have opposed pistons in one or more cylinders, with the piston motion determined by cams. Ports, for intake and exhaust, are at one end of the cylinder, opened or closed by one piston, with the combustion chamber at the other end, and the engine being well suited to the optional use of a combustion chamber separate from the cylinder and with the communicating passages controlled by the other piston. That arrangement makes the engine particularly suitable for using heavy or unconventional fuels. The cam profile provides for a four-strok...

청구항

An engine, comprising at least one cylinder, a pair of opposed pistons in said cylinder including a power piston and an intake piston and defining a variable space therebetween, means interconnecting said pistons to convert axial movement of said pistons in said cylinder into rotary motion, means for delivering combustion fuel into said space between said pistons, means in said cylinder defining an exhaust port and an air intake port, said ports being positioned in said cylinder so that they are covered and uncovered by said power piston, said intake pis...
