Re-Manufactured Diesel Fuel Injector 095000-9730 23670-59037Compatible for Toyota Landcruiser V8 200 Series engine 1VD-FTV

Influence of Nozzle Cone Angle on Diesel Engine Performance The nozzle cone angle has a great influence on the formation and combustion of the diesel engine mixture, and is an important parameter of the injector. Under the condition of the number of nozzle holes and the diameter of the nozzle holes, the development of the sprayed oil beam in the combustion chamber is also different when the cone angle of the nozzle holes is different.
With the increase of nozzle cone angle, the injection range becomes larger. When the cone angle of the injection hole is too large, the fuel is easily injected into the top clearance of the piston and enters the squash area during the compression process, the combustion of the diesel engine is insufficient, and the soot will also increase; The crushing effect of the lip makes the fuel directly enter the pit, and more fuel is distributed along the wall, which cannot give full play to the advantages of the mutual movement of the atomized oil and gas in the space, and the combustion cannot be fully carried out. Therefore, it is necessary to select an appropriate nozzle cone angle so that the oil beam matches the shape of the combustion chamber to obtain better combustion characteristics and lower emissions. On the basis of the previous section, the injectors of the two schemes S1 and S2 are selected according to engineering experience, the flow rate of the injectors is 750mL/min, and the cone angles of the nozzle holes are 148° and 150° respectively
Full-load performance curves for different nozzle angles. In all speed ranges, the corresponding full-load performances of the injectors of the two schemes S1 and S2 are basically the same. is the weighted ratio emission calculation result of diesel engine 13 working conditions when S1 and S2 injectors are used respectively
