Abstract
A fuel-air regulating system for hot gas engines in which a correctly selected ratio between fuel and air is maintained in spite of variations in the engine load. The system comprises temperature-controlled means for supplying fuel and air required for the combustion in a constant amount per unit of time which exceeds that which the engine requires for maximum power output when the high temperature level of the working gas had dropped to a predetermined lower temperature limit and for reducing the fuel and air supply to a constant amount per unit of time which is less than the amount required at idling of the engine when the temperature of the working gas has reached its predetermined upper limit.
Claims3
A system for regulating the supply of air and fuel to the combustion chamber of a hot gas engine operating in two heat generating modes to permit the high temperature level of the working gas in said combustion chamber to vary between a predetermined upper limit and a predetermined lower limit with small deviations above and below a predetermined temperature, comprising:
- a. means for supplying a mixture of fuel and air to the combustion chamber;
- and
- b. temperature controlled means effective to increase the supply of said mixture to a constant quantity per unit of time that exceeds that required by the engine for maximum output when the high temperature level of the working gas has dropped to its lower limit below the desired temperature and to reduce the supply of said mixture to a constant quantity per unit of time that is less than that required for the idling of the engine when the temperature of the working gas has reached its upper limit above the desired temperature.
