ABSTRACT:
A precision cast engine has a piston unit and a rotor unit to translate linear thrust from the piston unit into rotary power. Each piston rod is attached to a thrust absorber carriage running on precision bearings to eliminate piston drag on the cylinder walls. One or more drive rods extend from the carriage each into a curved groove on a power rotor to rotate it to transmit power via one or more drive shafts connected to drive components of transportation or other devices. An air intake valve on each piston provides automatic self aspirating to force combusted gasses out and draw in a controlled recharge of air for the fuel air mix.
