Abstract
A combustion system may include a piston, a fuel injector, and a cylinder. At a main fuel injection stage, the fuel injector injects a main fuel into the cylinder in sequence to drive the piston to work. A method for controlling the combustion system includes controlling the fuel injector to execute a first-stage main fuel injection in a compression stroke, the first-stage main fuel injection includes at least one injection, and continues till a power stroke such that the cylinder pressure in the cylinder reaches a target pressure peak value; and before the cylinder pressure in the cylinder reaches a descending critical point, executing a second-stage main fuel injection, the second-stage main fuel injection includes at least one injection, and the fuel injected in the second-stage main fuel injection and the fuel injected in the first-stage main fuel injection are superimposed.
