APPARATUS FOR CUTTING-OFF FUEL SUPPLY TO INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: for cutting-off fuel supply into a Diesel a force is eliminated from accelerator pedal 1. This is result in turning-on electric switch 10 and current is fed to closing member 1 which passes compressed air from receiver 14 to the first power pneumatic cylinder 3. The cylinder close gate 4 in inlet pipe line 5 and exhaust gases flow from the Diesel through a by-pass pipe line 6 whose inner cross-section is less than inner cross- section of outlet pipe line 5. A pressure occurs downstream of gate 4 within pipe line 5. The pressure acts on a rack of fuel pump 9 through pipe line 7 and the second power pneumatic cylinder 8. As the result the fuel supply to the Diesel is cut-off. EFFECT: enhanced reliability. 1 dwg
