摘要:针对自主开发的高压共轨电控柴油机,以经济性作为优化目标,以排放物的量值低于排放法规所限定的量值为约束条件,利用离线稳态优化标定方法,对控制参数如轨压、喷油提前角等的MAP进行了优化标定;研究了轨压、喷油提前角等参数对燃油消耗率和NOx排放的影响。研究结果表明:经控制参数优化,在全工况下,该高压共轨柴油机的燃油消耗率下降约为6%。 |

Abstract:In order to optimize the economic performance of a self-developed high pressure common rail electronic control diesel engine, as well as limit the emissions within the regulations standard, the MAP of its controlling parameters, such as common rail pressure, injection advance angle, etc. are calibrated optimally with the method of off-line stationary optimum calibration. The influence of the above mentioned parameters on fuel consumption rate and NOx emission are studied. Research results showed that after the optimization, the fuel consumption rate of this high pressure common rail diesel engine decreased about 6%. |
