Johnson, K A

The patent describes a vehicle power plant that includes a piston engine having combustion cylinders, each engine cylinder comprising an end wall, annular side wall, combustion air intake passage means connected to the cylinder end wall, and an exhaust passage means extending from the cylinder end wall for exhausting products of combustion from the combustion cylinder. The improvement described here comprises novel means for cooling the engine cylinders, the cooling means comprising a coolant chamber surrounding each engine cylinder; a fan means; a first conduit means for transmitting coolant air from the fan means to the individual coolant chambers; a second conduit means for directing spent coolant air from the individual coolant chambers to an area external to the vehicle; the cooling means being a completely confined system wherein all of the engine coolant air is sealed from escape while traveling through the first conduit means, the engine cylinders, and the second conduit means; each coolant chamber being defined by an annular shroud wall surrounding the cylinder side wall, and a head member overlying the cylinder end wall.
