Abstract
1305674 Controlling fuel supply electrically UNITED STIRLING (SWEDEN) AB & CO KB 21 May 1971 16259/71 Heading G1N [Also in Divisions F1 F4 G3] In an external combustion hot gas engine, e.g. a Stirling engine, fuel is fed under constant pressure to an atomizer in a combustion chamber 4 via a valve PV which is closed and opened alternately during time intervals of a constant frequency and to a constant degree of opening, the ratio of open to closed periods in each time interval t (i.e. mark/space ratio of valve control pulses) being varied in order to regulate the mean rate of fuel supply to the atomizer. Signals from a combustion chamber temperature sensor 5 are amplified at 6 and compared with a desired temperature value in a unit 7 and the resultant difference value signal is fed to a pulse with modulator PG together with a signal from a frequency generator FG. The output of PG is a pulse train the widths #t of the successive pulses of which vary with the difference between the actual and desired temperature. The pulse train is fed to a solenoid of valve PV, the leading edges of the pulses occurring at a constant frequency and causing the opening of valve PV while the trailing edge of each pulse causes the valve to close at a time #t after each opening thereof. #t may be varied between 0 and 100% of the time interval t. Combustion air is fed to chamber 4 via a conduit 8, being driven by an impeller I. The impeller delivery is governed by signals from a diode function generator DFG in dependence upon signals from the temperature comparator unit 7.
