METHOD OF FUEL SUPPLY CONTROL AND DEVICE FOR INTERNAL COMBUSTION ENGINE CONTROL Russian patent published in 2009 - IPC F02D41/30 

FIELD: engine engineering.

SUBSTANCE: invention relates to engine engineering, particularly to fuel instrumentation in internal combustion engines control and adjustment. Fuel supply control method provides for fuel supply controlling according to request signal and limiting to a maximum allowable value in order to avoid undesirable operational conditions. Maximum allowable value of fuel supply is changed in time according to the measured parametres and in accordance with change of engine operation parametre passing through the low frequencies filter. The internal combustion engine control device includes regulator responding to a request signal and feedback signal to generate fuel request signal, fuel limiter responsible for engine performance parametres to enable adaptive fuel limitation. The fuel limiter contains low frequency filter being responsive to engine performance parametre signal in order to generate filtered signal. The above mentioned control device also includes multiplier being responsive to the filtered signal and maximum power level signal in order to generate fuel supply limiting signal. The controller is also available in the device, which responds to an adaptive limitation of fuel supply and fuel request for fuel supply control.

EFFECT: prevention of both engine overloading and engine units failure.
