A radial cam driven internal combustion engine has connecting rod guide pins that slide into ends of the connecting rods, allowing the connecting rods to slide freely linearly while applying side loads on the connecting rods to the crankcase. The stationary guide pins protrude out from a center ring that floats over the central drive shaft. These pins are grooved to allow the pressure inside the connecting rod to escape. Each piston dwells at top dead center long enough to create a fixed volume environment and for all the fuel in the cylinder to be consumed.
