COMBINED COMPUTERISED SYSTEM OF ADJUSTMENT OF THERMAL MACHINE FUEL ADJUSTMENT Russian patent published in 2010 - IPC F02D45/00 F02B51/00 F02M53/00 

Abstract RU 2397348 C2

FIELD: engines and pumps.

SUBSTANCE: proposed system comprises fuel pump, fuel tank, thermal machine control component, booster valve, safety valve and booster valve. Said system additionally incorporates: first fuel metre to measure fuel temperature at high-pressure pumps inlets, second metre to measure output of thermal machine, third metre to measure temperature of fuel bled from fuel tank by fuel pump, two-way bypass valve arranged between fuel gas heater and exhaust manifold, first, second and third setpoint adjusters and first, second and third comparators. Third comparator is connected with third metre and third setpoint adjuster. Second comparator is connected with second metre and second setpoint adjuster. First comparator is connected with first metre. First setpoint adjuster, second and third comparators and two-way bypass valve drive. First metre, first setpoint adjuster, and two-valve bypass valve with drive make temperature controller that regulates temperature in compliance of current temperature deviation from preset temperature. Second metre, second setpoint adjuster, and two-valve bypass valve with drive make temperature controller that regulates temperature in compliance with thermal machine power output disturbance (first disturbance). Third metre, third setpoint adjuster, third comparator and two-valve bypass valve with drive make temperature controller that regulates temperature in compliance with current temperature of fuel bled from fuel tank (second disturbance). Functions of first, second and third setpoint adjusters, first, second and third comparators are fulfilled by microprocessor controller that ensure required static and dynamic operating parametres of proposed system in compliance with programmed algorithms.

EFFECT: higher fuel efficiency.
