METHOD OF CONTROLLING PORTIONS OF AIR AND FUEL IN MULTI- CYLINDER INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

Abstract RU 2027051 C1

FIELD: engine engineering. SUBSTANCE: method includes recording position of an acceleration pedal, shaping a signal depending on position of the acceleration pedal, which determines position of a throttle gate, shaping a signal which defines portions of fuel and air supplied to the engine cylinders depending on parameters of engine operation. The portion of fuel is determined and fuel is injected before suction stroke. Portion of fuel for subsequent suction stroke is calculated accounting for a portion of air which is fed in the cylinder at subsequent position of the throttle gate at the subsequent suction stroke. A moment of changing position of the throttle gate is delayed relatively the moment of changing position of the acceleration pedal during changing position of the acceleration pedal. Position of the throttle gate is changed at suction of the portion of fuel calculated for the position of the throttle gate. EFFECT: enhanced accuracy of controlling. 8 cl, 5 dwg
