Abstract

112,464. Aktiebolaget Wigelius Motorer. Jan. 5, 1917, [Convention date]. Two-stroke-cycle engines.- In a compound engine in which the high-pressure cylinder 1 is scavenged during expansion in the low-pressure cylinder 3 and the high-pressure piston 2 controls the exhaust from the low-pressure cylinder, the scavenging is carried on at a sufficient pressure to prevent the pressure in the cylinder 3 from falling below atmospheric during the part of the expansion period in which the port 7 between the cylinder is closed by the piston 2. The scavengng air is compressed beneath the lowpressure piston 4 and expelled though a valve 11 and a conduit 13 to a. valve 9 in the high-pressure cylinder. The valve 9 may be opened automatically by the presure of the scavenging air, or regulated simultaneously with the regulation of the charge. The high-pressure cylinder has an inlet valve 8 for fuel and air, and exhaust is expelled from the low-pressure cylinder through a recess 6 in the high-pressure piston and an outlet 5. Ignition in the high-pressure cylinder may take place at constant pressure, and the two cranks are preferably inclined at about 110 degrees to each other.
