  "textContent": "In a control method for the combustion system, spatial intensities of entrainment effects in a cylinder of fuel sprays of the two injections can be superimposed by means of two main fuel injections, two organizations of the fuel sprays for a flow field in the cylinder are implemented, by determining a duration and a first injection pressure of first main fuel injection, a cylinder pressure can at least reach an upper limit threshold of the cylinder pressure; and during second main fuel injection, in a time period when the cylinder pressure drops from the upper limit threshold of the cylinder pressure to a set cylinder pressure, a change rate of the curve slope of a cylinder pressure change curve at each time point is within a set range of slope change rates, and a rotation angle of a crankshaft is not smaller than a first preset rotation angle.",
