Definitions

  • turbo-supercharger air pres-sure depends on exhaust back pressure.
  • a waste gate is generally provided to open and close the exhaust duct for varying turbo-supercharger speed.
  • actuation of the air throttle valve toward the open position generally produces up to about 90% of the total engine power increase available through throttle control during about the first half of throttle motion. Further actuation produces relatively little change in power.
  • turbo-superchargers either were made to operate continually during all engine ranges, or were arranged for manual cut-in, or rather complex control systems were used to achieve required power by varying the output of the supercharger as engine requirements dictate.
  • An object of the present invention is to make use of the turbo-supercharger only during high power operation by directly coordinating the operations of the throttle and waste gate.
  • Another object of the invention is to improve eificiency of engine operation by providing a means for energizing the turbo-supercharger only during that range of throttle operation which produces little increase in engine power.
  • FIG. 1 is a longitudinal cross-sectional view of a preferred mechanical coordinator control device taken substantially on the line 11 of FIG. ,2.
  • FIG. 2 is a side view of the preferred coordinator.
  • FIG. 3 is a cross-sectional View taken substantially on the line 3-3 of FIG. 2.
  • FIG. 4 is a diagram illustrating one type of relationship avail-able with the coordinator.
  • FIG. 5 is a diagrammatic view of a preferred engine utilizing the present coordinator.
  • FIG. 6 is a top view of the coordinator shown in FIG. 2.
  • a preferred aircraft engine 10 shown diagrammatically, for which the present control system is applicable, has cylinders 11, an air intake manifold 12, and an exhaust manifold 13.
  • a turbo-supercharger 14 is provided in which exhaust gas selectively directed through a branch duct 13A of the exhaust manifold 13 drives a turbine 15 which is driving connected to a supercharger 16 which, relative to the driving input, delivers compressed air to the air intake manifold 12.
  • a throttle valve 17 is provided in the manifold 12.
  • Operation of the turbo-supercharger 14 is controlled by means of a waste gate 19 provided in the exhaust outlet 20 which bypasses the turbine 15 and is connected with the outlet 21 of the turbine 15. With the waste gate 19 open, no exhaust pressure is available to run the turbine and hence no supercharging occurs. As the waste gate 19 is closed, exhaust back pressure builds and energizes the turbine 15 to operate the supercharger 16.
  • FIGS. l-3 and 5 A practical, simplified approach to coordinating waste gate and throttle operation is the mechanical coordinator device 24, illustrated in FIGS. l-3 and 5.
  • a pair of support plates 25 are mounted and spaced apart by any means such as bolts 26, nuts 27 and spacers 28.
  • An input shaft 29 is rotatably carried by bearings 31 mounted in the plates 25, preferably extending therethrough as shown in FIGS. 1, 3 and 5, and provided with an end lever 30.
  • a control rod 32 or the like is connected to the lever 30 as in FIG. 5 and extends to the pilots compartment (not shown).
  • a lever assembly 33 having a hub 34 and a pair of arms 35 and 36, is secured to the input shaft 29 and rotates therewith.
  • a pair of coaxially connected output shafts 40 and 41 are separately rotatably carried by bearings 42 mounted in the plates 25 and extend oppositely through the plates 25 as shown in FIGS. 1 and 6.
  • the output shafts carry end levers 43 and 44 respectively connected by control rods 45 and 46 or the like to, respectively, the waste gate 19 and the throttle valve 17, as shown in FIG. 5.
  • a pair of arms 47 and 48 are secured respectively to the output shafts 40 and 41.
  • the ends of a pair of links 50 are connected by any means such as pins 52 to the arms 35 and 47.
  • the ends of another pair of links 51 are similarly connected to the ends of the arms 36 and 48.
