New Injector Nozzle Dsla128p5510 0433175510 for Fuel Injector 0445120231 0445120445

(1) Through the change of the diameter of the injection hole of the diesel engine, the three-dimensional numerical simulation of the fuel flow in the injection hole is carried out. The results show that under different hole diameters, the flow of the fuel in the nozzle and the change of its flow velocity and pressure. As the pressure difference AP between the inlet and outlet becomes larger, the flow velocity at the outlet of the nozzle hole increases, which further improves the atomization of the fuel, greatly increases the evaporation surface area in contact with the surrounding air, and accelerates the heat absorption process from the air and the droplet separation. The vaporization process plays an important role in the formation of the mixture, and finally the economy, power and emission indicators of the diesel engine have been improved
(2) Through the two-dimensional numerical simulation of the fuel flow in the inverted cone fuel injection hole of the diesel engine, it can reflect the flow of the fuel in the nozzle under different injection pressures and the change of its flow velocity with the pressure difference between the inlet and outlet Vp increases, the flow velocity at the nozzle hole increases, further improves the atomization of fuel, greatly increases the evaporation surface area in contact with the surrounding air, accelerates the heat absorption process from the air and the vaporization process of the liquid droplets, and affects the mixture gas. Formation played an important role in the final diesel engine economy, power and emission indicators have been improved.
(3) By comparison, the atomization effect of the inverted tapered fuel injection hole is better than that of the straight hole. Under the condition of a certain inlet and outlet pressure, as the taper of the fuel injection hole increases, the fuel flow in the nozzle The velocity tends to increase, which reduces the average diameter of the oil droplets, and the smaller the average diameter of the oil droplets sprayed by the combustion system, the better the atomization quality, which provides a theoretical basis for the optimal design and improvement of the fuel injection system.

Q10: How to test fuel injectors?
A10: Detect the dripping of fuel injector. Select the connector of the test instrument according to the model of the fuel injector and connect it well, then check the sealing O-ring group (replace it if it is found to be damaged), install the fuel injector on the test frame, press the oil pump key, adjust the pressure to the factory specified pressure of the tested vehicle (preferably 10% higher), and observe whether the fuel injector drips oil. If the leakage in 1min is greater than one drop (or according to the technical standard), replace the fuel injector.
