【摘要】 本文提出了以负荷特性为依据,对发动机在试验的大气条件下进行功率标定、功率修正和高压油泵油量标定的方法。并在油耗线法基础上建立了数学关系式,从而不仅可以对整个负荷特性进行恰当的修正,而且由于摆脱了油耗线法的局限,也可以应用于发动机任何工况的大气修正,克服了国标GB1105—74用定值C、β和估计值η_m0来修正所有工况的缺陷。更多还原

【Abstract】 This paper presents a method,based on the load characteristic curveof a naturally aspirated diesel engine under the actual ambient condition,of powercalibration and correction of a naturally aspirated engine and rated fuel delivery ofits injection pump with respect to the standard ambient condition.The mathema-tics relationship based on,but getting rid of limitation of,the fuel consumptioncurve method is set up to correct properly not only the whole load characteristiccurve but also any operating point of the engine.It can also be used to overcomethe defects of current Chinese National Standard correction method“GB1105-74”which corrects the same by means of keeping the values C and β constant andestimating the value of η_m0.更多还原
