TURBOCHARGER DIESEL FUEL FEED REGULATOR Russian patent published in 2019 - IPC F02D1/00 F02D1/10 F02D23/02 

FIELD: internal combustion engines.

SUBSTANCE: invention can be used in the field of automatic control of internal combustion engines. Diesel fuel (1) with turbocharger fuel supply regulator comprises a pneumatic sensing element (3), centrifugal sensing element (24), a mechanical fuel feed corrector, fuel feed dispenser (13), main lever (11) and adder lever (10). Pneumatic sensitive element of pressure of supercharging air contains membrane (4) connected on one side by pipeline (6) with inlet branch pipe (5) of diesel engine, and on other side with spring (7) and rod (8). Rod is articulated with slider (9) with the summing lever. Upper arm of summing lever is connected by stem to spring-loaded membrane, lower arm is connected by hinge to end of main lever and centrifugal sensitive element, and middle point of summing lever is connected to fuel supply proportioning device. Summing lever and the fuel supply metering device form a summation mechanism with the number of degrees of freedom w = 2. Movement of summation lever ends is limited by two fixed stops. Main lever is connected with main control spring (17) with diesel control lever (18). Additional mechanical fuel feed corrector is made in form of located on lower part of summing lever movable stop (12), resting on fixed prism (16), fixed on body at an angle to its vertical position.

EFFECT: technical result consists in providing possibility of diesel engine operation in transient modes by economic characteristic and improvement of control accuracy.
