Injector FAQ

FAQ: Common Rail Fuel Injector FAQ. Spring Break?

ERIKC Answer:In spite of the permanent deformation caused by the drop of the steel rigidity of the pressure regulating spring of the injector, the breakage often occurs, which has become one of the weak links of the injector. This is mainly due to the poor fatigue resistance of spring steel under high-temperature, high-load, high-frequency operating conditions.

Solution: Improve fatigue resistance, select high-quality heat-resistant and fatigue-resistant materials, and perform surface treatment shot-peening with enhanced fatigue resistance. In order to make the pressure regulating spring work safe and reliable. To reduce the spring power load, the injector can be designed so that the spring can be immersed in the diesel oil in the injector body. When the injector is working, the spring's working ring can generate hydraulic “buffer” and some lubrication when in contact. In order to prevent the contact surface from forming a pockmarked surface, the spring breaks.

FAQ: Common Rail Fuel Injector Frequently Asked Questions. Needle body wear?

ERIKC Answer:The needle valve body face is subjected to frequent reciprocating motions of the needle valve, and a pit is gradually formed over time, thereby increasing the needle valve lift and affecting the normal operation of the injector. The needle body can be grinded on a grinding bed to grind this end surface and then ground with a fine abrasive paste on a glass plate.
