[0086] Example
[0087] According to the estimation method, a certain diesel engine new machine is an example, a certain diesel plunger diameter is 10mm, the plunger parameter is 2.74 mm, the constant is 1.122, the ring gear diameter is 28.6 mm, and the fixed rotation speed is 1500R / min, The mechanical loss efficiency of the diesel engine new machine is 17.1 kW. After the diesel air load operation is detected to 3 mm, calculated to obtain an empty load fuel consumption of 0.874 g / s, the maximum fuel position of the diesel engine at 1500R / min fueling the right The displacement is 15mm, the calculation is calculated to obtain a maximum oil supply volume of 15.8 g / s, and the calculated power value is 292.1 kW. The calculated power value and the external characteristic map are like image 3 As shown, the abscissa in the figure indicates that the diesel speed, the ordinate represents the power value of the diesel engine; the circle of the circle of 1500r / min is shown in the fi...
