Abstract:
A four-cycle engine comprising:a fuel source providing a fuel and lubricant mixture and a carburetor mixing the fuel mixture with air and converting the mixture to vapor form; a crank shaft chamber and a pathway from the carburetor to the crank shaft chamber, a reciprocating piston in the chamber and a combustion chamber overlying the piston, said reciprocating piston operable between the crank shaft chamber and combustion chamber to alternately increase and decrease the volumes in the crank case chamber and combustion chamber; working components between the crank case chamber and combustion chamber which define a mixed fuel pathway from the crank case chamber to the combustion chamber and which pathway defines a volume; said volume of the mixed fuel pathway between the crankcase chamber and the combustion chamber sized to be within a range of about 2 to 4 times the displacement of the piston.
