SYSTEM FOR CONTROLLING FUEL SUPPLY TO ENGINE ON TEST BENCH Russian patent published in 2025 - IPC G01M15/14 F01D21/16 F02C9/46 

FIELD: mechanical engineering; testing.

SUBSTANCE: invention relates to a system for controlling fuel supply to an engine on an engine test bench. System comprises a first actuator configured to control the supply of fuel to the engine based on a control signal from the test bench control unit, and a second actuator configured to stop or resume the supply of fuel to the engine based on the control signal from the control unit. System differs by the fact that it contains at least one non-volatile control means, which is made with possibility of interaction with one of actuators for transfer of control action. Controlling the supply of fuel to the engine in an emergency situation on the test bench for testing engines provides that when the supply is stopped, the actuator connected to the non-volatile fuel supply control means, to control fuel supply to the engine, control action is supplied to the actuator using the said non-volatile means.

EFFECT: invention provides higher safety of tests.
