The Diesel Engine Fuel Injector - Components & Assembly · 模型 45638
The fuel injector is used on a diesel engine. It injects highly pressurised diesel, supplied by a fuel pump, into the combustion chamber of the engine cylinder. The spring is located in the body above the distance piece. The nozzle pin is placed inside the nozzle and attached to the body by means of nozzle holder. The screw adjuster is placed over the spring from the other side (top) of the body. The adjusting screw is located in the cap and it is held in position by the lock-nut. The body has a narrow hole of 2 mm diameter, through which the pressurised diesel from the fuel pump enters the nozzle. When it exceeds the set pressure of the spring, the diesel is sprayed through the nozzle into the cylinder and as soon as the pressure falls back, the injection ceases. The excess oil left-over in the injector, flows back through the clearance around the distance piece into the over-flow exit, provided at location M6.* - The model has been created on Siemens NX. - The constraints have been created by aligning CSYS to CSYS as interfaces. - Also, the screw threads have been created by using WAVE Geometry Linker. - All the components are in STL Format for 3D Printing Process. *Narayana K.L., Machine Drawing 3rd Edition
