Embodiment Construction
[0013] Offline detection establishes the actual engine speed and follows the principle of minimum fuel consumption rate to control the relationship between the engine output torque and the speed under the current fuel injection condition and draw the mechanical characteristic curve 1. For a certain engine, the curve 1 remains unchanged. The method is as follows: According to the speed characteristic diagram of the internal combustion engine, the speed value and torque value at the minimum fuel consumption rate are obtained under different fuel injection quantities, and the speed value and torque value determine a point on a curve. When changing the fuel injection quantity, the curve can be obtained There are more different points on 1. When the engine speed exceeds the rated speed, the fuel injection quantity will no longer increase. By fitting these points to the curve, the functional relationship between the engine output torque and the speed under the minimum fuel consumption...
