| Abstract: | Fuel injector is the key component of the high-pressure common-rail fuel injection system in diesel engine.The key parts of the fuel injector parameters and choice will affect the diesel injection process,thus affecting the operating characteristics of the diesel engine.A one-dimensional simulation model of a diesel injector was developed under simulation software to study the influence of different structural parameters and the viscosity and density of different fuels to the needle valve movement rules,injection rate and injection quantity,etc.The research results have a certain reference value to the choice of fuel and the key parts design of the injector. |
