Title: The fuel quantity correction and calibration of the high pressure common-rail diesel engine
Abstract: The correction methods and matching strategy of fuel quantity were studied with the high pressure common-rail diesel engine.The influences of processing precision difference of the individual injector,diversity of the injector driven current and the pressure fluctuation affecting the coherence of the injection quantity were analyzed.The injection fuel quantity was corrected by feed-back control of the driven current and compensation of the energizing pulse.By analyzing the engine operation point,the matching strategy of fuel quantity on common-rail diesel engine was designed.The fuel quantity MAP was calibrated with an asymmetric step according to the frequency and importance of the engine operation.Finally,experiments were done on a test bench to verify the correction strategies.Experimental results show that the control and compensation strategies could improve the coherence of the injection fuel quantity.
