Abstract

868,228. Regulating. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Dec. 3, 1958 [Dec. 5,1957], No. 38957/58. Class 7(6). The full-load delivery position of a fuel injection pump control rod is varied for different fuels by means responding to the density or viscosity of the fuel being used. In Fig. 1 the fuel is passed through a float chamber 8 containing a float 7 connected to an auxiliary stop 6. When a light fuel, such as petrol, is used the fullload delivery is fixed by a stop 4 but when diesel oil is used the float 7 rises to move the stop 6 in front of the stop 4 to limit the maximum delivery to a lower value. In a modification, Fig. 2, the float is replaced by a container 17, through which the fuel passes, carried by a pivoted arm 18 with a counterweight 20. The container, which is connected to the auxiliary stop 6, is positioned against an upper stop 21 when using light fuel, heavy fuel causing it to move down against a stop 22. The container may actuate the stop 6 through a solenoid. In Fig. 4 the auxiliary stop 6 is connected to a spring-loaded piston 35 in a chamber 34 connected in the fuel line 40 returning leakage fuel from the injectors to the fuel tank. When using light fuel a large amount escapes through pipe 40 and a restriction 42 therein produces a pressure build-up which depresses piston 35 to move the stop 6 away from stop 4. When using heavy fuel, very little fuel escapes through pipe 40 and no pressure build-up occurs so that the piston 35 positions the stop 6 in front of stop 4 to reduce the full-load delivery. In a modification, Fig. 5, the fuel flows to the engine through a clearance space around a piston 44 connected to the stop 6, a high viscosity fuel causing the piston to rise whereas a low viscosity fuel leaves it undisturbed.
