<p>A two-cycle internal combustion engine, which has two cylinders, has a horizontally disposed crankshaft with the crankcase divided into first and second chambers communicating with each of the cylinders and a third chamber communicating with the carburetor and with each of the first and second chambers through reed valves. Drainage, which comprises oil with some gasoline, is collected in the lowermost portion of each of the first and second chambers and directed past a check valve into a passage for supply to the other cylinder when reduced pressure exists therein. The drainage, which accummulates in the third chamber, is supplied to one of the two connecting passages through a check valve for supply to the cylinder connected to that passage.</p> |
