Title: Fuel/air ratio regulating systems for internal combustion engines
IPC: F02M41/12
Filed: 1975-02-26
Abstract: 1504632 Fuel injection regulation ROBERT BOSCH GmbH 26 Feb 1975 [1 March 1974] 7937/75 Heading F1B In a fuel/air ratio regulating system for an I. C. engine, the volume rate of flow of air through the induction pipe is measured, this measurement being used to define a desired fuel/air ratio value, and either the air-flow through the induction pipe or the quantity of fuel supplied is adjusted so as to  maintain the desired value. The command variable may be either air-flow, defined by the throttle valve position Fig. 1 or fuel demand Fig. 2 (not shown). In Fig. 1, the fuel flow is determined by regulator 20 controlled by motor 19. The regulator responds to pressure changes in the line 24 determined by the differential pressure valve 18 and the restrictor 26, the constant pressure head being supplied from the pump 16 and relief valve 17. Variation in air-flow caused by throttle valve position vary the position of vane 10 which actuates the variable restrictor 12 causing pressure variation in the control side of the valve 18, thus operating motor 19 and regulator 20. The power of spring 22 and the setting of the relief valve 17 determines the desired value of the fuel/air ratio. In a second embodiment fuel demand causes a motor to operate the throttle to provide the desired air-flow via a differential pressure valve 42, Fig. 3. Increased fuel demand, reduces pressure in line 36 allowing motor actuation from pressure changes in line 46. The air measuring system comprise a vane 37 which rotates boss 51 about a spindle 39, the boss and spindle forming a variable restrictor equivalent to that in Fig. 1 (13). The measuring system has a second vane for damping, movable within a chamber in the induction pipe wall and the regulator may be initially adjusted by means of lever 56. The system may be used in self-igniting, stratified charging type or conventional I. C. engines

Abstract: 472,262. Boiler furnaces. FRENGER, G. March 18, 1936, No. 8147. Convention date. Nov. 6, 1935. [Class 51 (i)] In a sectional boiler furnace for central heating, fuel is fed continuously or at short intervals so that it falls freely in the form of a fine stream from an orifice 9 downwardly through the combustion chamber 1 on to the top face of an upwardly projecting tuyere 6 arranged in the bottom of the chamber 1 and air is forced at a high velocity upwardly into the combustion chamber through perforations 7 in the tuyere which extends only partly across the combustion chamber in any direction. Fuel is fed to the orifice from a hopper 10 by means such as a screw 11 and the orifice is arranged at such a height that the heap of fuel collecting on the tuyere cannot reach up to the orifice. In the form shown, the invention is applied to an existing boiler furnace, the grate 2 of which is covered with refractory bricks 3 except for a central space 4 in which is mounted the tuyere 6. A fan supplies primary air to beneath the tuyere and may also supply secondary air through a pipe 28 to a chamber 16 in which it is heated before it issues from a pipe 15 directed downwardly towards the top of the tuyere. The primary air issues from the tuyere at a high velocity so as to cause a circulation within the chamber 1 as shown by the arrows. The fan motor 30 and the motor 31 driving the screw 11 may be controlled by a thermostat 8 arranged in the water outlet pipe 21.
