Abstract

The unsymmetrical free piston engine comprises a housing having a base portion with open upper and lower end portions and at least one side opening. An engine cylinder portion is positioned above the base portion and extending from the upper end of the base portion to an upper end of the cylinder portion and providing an open-ended combustion chamber. A cylinder head is detachably secured to the cylinder portion across a lower end. A balancing unit is mounted above the upper end of the cylinder portion, having a window in a side wall. A piston is provided in the cylinder portion having a piston rod extending from the piston through seals in a bottom of the balancing unit. A drive shaft extends through seals in an upper end of the balancing unit for connection with an energy absorbing device. The said drive shaft is operably connected to the piston rod.
