ABSTRACT:
A two-stroke cycle nonscavenged internal combustion engine operates under controlled detonating conditions without damage to the engine and with greatly enhanced fuel economy. The engine may have any desired number of cylinders operating initially on a two-stroke cycle with spark and then under auto ignition conditions. A variable compression device is provided in each cylinder to store excess energy liberated at peak pressures and to release it back to the piston during its power stroke. A Scotch yoke connection between the piston rod and crank shaft is laterally guided to eliminate side thrust. A bounce piston shock absorber is provided to assist piston reversal and dampen inertia forces. The fuel-air mixture is introduced under the piston, transferred through swirl passages, containing converging diverging nozzles, to the top of the piston, and exhaust gases exit under their own pressures trapping some so as to retain unburned hydro-carbon and oxygen radicals in the combustion zone for mixture with the fresh fuel-air mixture. These highly chemically active radicals initiate an auto ignited combustion which is controlled by the dilutent effects of the inert portions of the exhaust gases.
