Abstract

301,677. Silvestri, G., and Pedrotti, D. Feb. 18, 1928. Cylinders receiving liquid fuel. - In a twostroke-cycle engine the common combustion chamber 3 is connected to the cylinders 1 by passages 2, the shaft 28 being placed between the cylinder. The combustion chamber is conical and has interchangeable liners 25 to vary its volume. On the side of the chamber remote from the cylinders is or are mounted an annular valve 7 or a number of valves for scavenging air. On the same side of the chamber is an unjacketed vaporizer head 4 connected through a valved passage 9 to a fuel receiving vessel 5. The terminal exhaust ports 16 deliver into channels 13 and an exhaust pipe 30. At the end of the expansion stroke the flow of the exhaust causes a depression within the cylinders and combustion chamber; the valve or valves 7 open automatically .and air flows in. At the commencement of the return stroke of the pistons the valve 8 is opened through the linkage 19, 20, 21 by a cam 18 on the gudgeon; fuel then flows into the head 4 being directed upwardly bv the shape of the passage 9. It is heated in this head and mixed with some of the scavenging air compressed on the return stroke of the piston; the head is not scavenged, a small part of the products of the previous cycle being driven in front of the incoming fuel. An igniter 27 is placed in the head. Liquid fuel may be supplied to the vessel 5 through the opening 11 and delivered to the vaporizer by air supplied at the opening 12.
