Embodiment Construction
[0019] The fuel injection timing control strategy under the double plume combustion system is divided into two parts in the implementation process, one part is to determine the relative installation position between the fuel injector and the double plume combustion chamber, and the other part is to control the fuel injection timing through electronic fuel injection. The system determines the injection start point.
[0020] Due to the high requirements for the cooperation between the fuel jet and the shape of the combustion chamber in the double-plume combustion system, there are also high requirements for the installation position of the injector in the double-plume combustion system. Therefore, when designing the double-plume combustion system, the relative installation position between the injector and the double-plume combustion chamber should be determined first to ensure that the distribution ratio of the oil beam between the inner chamber and the outer chamber is 1:9.
