Description: |
| Abstract:
This invention has for its object to increase the efficiency of internal-combustion engines, and relates more especially to the means for introducing the fuel basis of the charge and to the means for maintaining in the explosion-chamber or working cylinder the conditions best suited to the operation of the engine.
Claims:
1. In an internal-combustion engine, the combination of a working cylinder, an auxiliary chamber communicating with the working cylinder through a relatively small but unobstructed passage to receive air from the working cylinder during the compression stroke and to discharge the same into the cylinder as the pressure therein is reduced, a vaporizer and igniter independent of said auxiliary chamber, and means to supply the fuel basis of the charge is sprayed into the working cylinder by air discharged from the auxiliary chamber and the pressure in the working cylinder is reduced, substantially as described.
2. In an internal-combustion engine, the combination of a working cylinder, an auxiliary chamber communicating with the working cylinder through a relatively small but unobstructed passage to receive air from the working cylinder during the compression stroke and to discharge the same into the cylinder as pressure therein is reduced, a nozzle through which the fuel basis of the charge is delivered to the auxiliary chamber, a vaporizer and igniter independent of said auxiliary chamber, and a pump timed to supply the fuel basis of the charge to said nozzle before the pressure in the cylinder is reduced, whereby the fuel basis of the charge is sprayed into the working cylinder by the air discharged from the auxiliary chamber and the pressure in the working cylinder is reduced, substantially as described.
