    摘要： A system for supplying a substantially uniform combustible fuel mixture for an internal combustion engine includes a compressed air supply line and a compressed fuel gas supply line, each having a first end connected to its respective pressurized supply, a metering orifice portion, and a second end connected to an appropriate part of the engine. At least one of the metering orifice portions is adjustable for establishing various desired air-to-fuel ratios for delivery to the combustion cylinder. The system includes a pressure regulating apparatus in at least one of the lines, between its first end and its metering orifice portion for maintaining substantially equal pressures at all times in the respective supply lines immediately upstream of their respective metering portions. The respective supply line pressures immediately downstream of the metering orifices are also kept substantially equal by connection of both supply lines to a common conduit or mixing chamber. Preferably a pressure regulating valve of the air-loaded or dome-loaded type, which has a controlling pressure chamber and operates in response to changes in fluid pressure in such control chamber, is located in one line and has its control chamber connected to a sensing means so the chamber pressure has a predetermined relationship at all times to the pressure in the other supply line. A temperature control device may also be used in one or both lines to prevent undesired variations in air or fuel gas temperatures which could adversely affect the uniformity of the combustible mixture at different times during operation.
