摘　　要：将WP10.336柴油机改变为双燃料发动机并进行了标定和试验。试验结果表明,双燃料发动机的动力性与原柴油机相当,外特性线上平均柴油替代率达到95.7%。双燃料发动机在1200 r/min时,中、高负荷下都有较高的热效率和柴油替代率,最大功率点对应的缸内最高爆发压力为14.82 MPa。A WP10.336 diesel engine was changed into a dual fuel engine,calibrated and tested.The test results show that the power performance of the dual fuel engine is equivalent to that of the original diesel engine,and the average diesel replacement rate reaches 95.7%observed from the external characteristic curve.The dual-fuel engine has been shown to achieve higher thermal efficiency and the diesel replacement rate at 1200 r/min under medium and high loads.The maximum combustion pressure corresponding to the maximum power output point is 14.82 MPa.
