High Quality Diesel Fuel Injection Pump 0 460 424 372 Distributor Pump 0460424372 Engine Parts

In order to improve the comprehensive performance and manufacturing efficiency of the pump body of the fuel injection system, precision extrusion is used to realise the efficient and green manufacturing of the variable pump body. Through the process design, the shape of the forging, the parting form and the die structure are initially determined, and the finite element method is used to simulate and analyse the precision extrusion process of the pump body, to study the flow rule of the metal in the cavity during the extrusion, the influence of the die structure on the extrusion, and the filling of the forging edges and corners.

The fuel injection system in a diesel engine is a fuel supply device that injects a certain amount of diesel fuel into the cylinder under a certain pressure using injectors. Variable pump pump body can adjust the output characteristics within a certain range according to the needs of the work, is an important part of the injection system. Variable pump pump body of the working environment is more complex, assembly precision requirements, the demand for a larger 1. Factory original production process using CNC cutting, cutting, low production efficiency and material waste is more serious. Precision extrusion technology is a high-efficiency, high-precision, high-quality and low-consumption advanced technology, forming parts not only high dimensional accuracy, good surface quality, high production efficiency, but also through the continuous metal flow to improve product performance, is an effective measure to achieve less cutting or even no-cutting processing. But on the other hand, the deformation resistance of the material during precision extrusion is large, and the requirements for equipment and moulds are high. The article carries out a research on the optimization of the precision extrusion process for the pump body of variable pumps, in order to improve the quality of the product and the production efficiency, and to realize the energy-saving, material-saving, and green environmental protection purposes of the production process.Higher injection pressure results in better fuel atomisation, more efficient combustion, lower fuel consumption, reduced exhaust emissions and diesel engine noise.
