Patent GB-131308-A (GB)
IPC: F02M1/00
Abstract: 131,308. Jelbart, F. S. Aug. 13, 1918, [Convention date]. Vaporizers, external.-Liquid fuel is heated in a chamber formed in the cylinder head and then vaporized in an adjoining chamber before being admitted to the cylinder through terminal ports controlled by the piston. According to the construction shown in Fig. 1, fuel is supplied to a chamber 13 having an outlet pipe 15 leading to the float chamber of a carburettor from which charges are drawn into a vaporizing chamber 12 through a mechanically-actuated valve 21 bv the suction in the crank case, the chamber 12 and the crank casing being connected by a pipe 27<1>. The vaporizer also communicates with the crank chamber through a pipe 28, which opens into a scavenging-air transfer passage, adjacent a cylinder inlet port 29. During the compression stroke in the cylinder 11, air is drawn into the crank chamber through a valve 33 and combustible mixture enters the vaporiser from the carburettor. At the end of the expansion stroke, air for scavenging enters the cylinder through the port 29, some of the air in the crank-casing passing through the pipe 27<1> and forcing combustible mixture from the vaporizer into the cylinder through the pipe 28. According to the modified method of working, the pipe 27<1> may be dispensed with, the charges being expelled from the vaporizer by compressed air delivered through the port 27. Further, the admission of air to the crank case may be dispensed with, the charge drawn into the crank chamber comprising only combustible mixture from the chamber 12. When using a light fuel, pre-heating may be dispensed with. Fuel may be pumped directly into the vaporizing chamber, in which case a. carburettor is dispensed with.
