Title: Direct power type cylindrical engine
Inventor: KIM JONG-DAE
IPC: F02B75/32
Filed: 1986-03-31
Granted: 1989-07-24
Abstract: This invention increases power by connecting directly with a connecting-rod and main shaft.  Setting radially several cylinders of which each connecting rod is jointed with the rod supporting disc that on the main shaft can frictionally roll over by the inclination plate and a thrust bearing, the forcing pressure of the piston only changes the slope of the supporting disc (11), turns the inclination plate (8).  Thus the loss may be the least, for the motion of the piston which moves slowly and speedily in all the stroke, during an adiabatic compresive process a heat transfer can be reduced and during an a.e.p. the pressure is more even.
