Definitions

  • the present invention relates to a regulating device for a combustion engine driving an electric generator, particularly for vehicles, which regulates the supply of fuel to the engine as well as the excitation of the generator in dependence on the engine load.
  • a device which influences the regulation of the fuel supply during the regulation of the excitation in such a way that the increase of the fuel supply beyond an adjustable limit amount is prevented.
  • the device can take the form of a movable stop which prevents the adjustment oi' the fuel supply regulator to an amount exceeding the limit amount.
  • the same speed-controlled governor may regulate the fuel supply and the excitation of the generator, and between this governor and the device regulating the fuel supply av exible coupling may be provided.
  • Fig. 1 shows a combustion engine coupled to an electric generator, which is operated at constant speed, and rhas a control device by means of which three different limit amounts for the fuel supply can be set.
  • Fig. 2 shows a regulating device for a combustion engine with three operating speeds, a special limit amount being set for each speed.
  • Fig, 3 is shown a modification of the controller drum of Fig. 2.
  • FIG. 5 shows in detail a switch-controlled blocking device in association with a servomotor.
  • the combustion engine drives a--main generator 2, and an auxiliary generator 4.
  • the latter which also can have a sepa- 5 rate drive, serves among other things for the excitation of the main generator 2, of which the output circuit is connected at 3.
  • the excitation is varied by means of the regulating resistance 5.
  • the governor 8 driven by the engine I through l0 the shaft 1 serves to regulate the supply'of fuel to the engine as well as to regulate the excitation f of the generator 2 in dependence on the load of the engine.
  • the sleeve 9 of the governor 3 actuates the lever I0, which swings on the fixed l5 fulcrum I2 and is connected to the rod I3.
  • the 35 regulation of the fuel supply is influenced by a device which is formed as a controllably movable stop which prevents the increase of the supply of fuel beyond an adjustable limit amount.
  • 'Ihe stop comprises bent lever 21 which limits the 40 travel of the rack 22 towards the left.
  • the mode of operation of the regulating device is as follows:
  • the stop comprising the vertical arm of the angle lever 21 permits, in the position shown in the drawings, a displacement of the rack 22 toward the left up to the limit position (III) 50
  • are without current, because the drum switch 33 is in the position M3.
  • the rack 22 is adjusted for the delivery of the greatest possible amount of fuel by the fuel pump 23, which, in this example, corresponds to the full load fuel capacity and full load torque of the engine I.
  • the rod I3 is so adjusted that in the central or shut-olf position, as shown in the drawings, ofthe slide valve I4, which corresponds to the position of the governor when the output of the engine is to be kept constant, the rack 22 strikes against the stop 21 and the spring plate 2
  • conduit I6 is connected with the nipple 56 so that all the pressure oil above the piston I5 is allowed to drain ofi' freely.
  • the coil 56 becomes deenergized and spring 55 pulls the armature downwardly.
  • Cock 52 is Withdrawn from the locking position II into the position I, in which the supply line nipple 51 is connected with conduit I6 and nipple I8 with conduit I1.
  • Such a blocking device can be dispensed with in the case of partial or exclusive self-excitation of the generator 2.
  • this must be so adjusted that, when the switch 46 is in the neutral position and the separate excitation cut out, it is not suftlcient to bring the generator 2 up to voltage. Itis then permissible, without damage to the generator, to cut in the full separate excitation when the switch 46 is in the position M1.
  • the voltage of the main generator is then, however, built up. comparatively slowly so that the servomotor I4, I5 has time gradually to cut in a part oi' the resistance 5.
  • an internal combustion engine-electric power unit which comprises an internal combustion engine having fuel supply means, a main electric generator ldriven-by the engine, means for exciting the main generator, regulating apparatus operatively connecting the fuel supply means and the means for exciting the generator, whereby the quantity of fuel admitted to the engine and the excitation of the main generator are automatically influenced, and an adjustable limitation device in operative association with the fuel supply means and the regulating apparatus for limiting the increase of fuel under the action of the regulating device.
