Common rail relief valve open failure 1. The amount of oil on the uphill is large, the rail pressure is easy to be low, and the pressure relief valve is not easy to open. 2. There is no sensor on the pressure relief valve for the ECU. How does the ECU judge that the pressure […]

1, the impact of needle lift: As shown in the figure below: The blue curve shows the injection curve when the needle valve lift of the injector is 250 μm. When the needle lift is 280 μm, the injection curve will be in the state shown by the red curve.commonrailparts When the needle lift is […]
I believe that the common rail injectors and friends engaged in vehicle maintenance are no strangers to the concept of gaskets commonrailparts during normal use and repair. So what are the adjustable gaskets inside all kinds of common rail injectors? What are the functions and adjustment methods of common rail injector gaskets? In fact, the […]
Due to improper operation when installing the injector, the original good performance of the broken-out injector assembly will result in poor operation or inoperability of the diesel engine. Therefore, when installing the injector, you must pay attention to the following aspects: (1) The injector gasket should not be leaked. The purpose of the sealing […]
First, the fault judgment: Usually: the engine is found to be abnormal or insufficiently motivated. The engine is not evenly distributed at high, medium and low speeds. The rhythmic vibrating muffler emits black smoke and fires. The lack of cylinder in the engine can cause 02112860 the car to consume a lot of fuel. Black […]
Solenoid Function Solenoid technology is an electro-mechanical device that controls the flow of a media through a pipe by opening or closing the valve orifices. The solenoid assembly consists of a coil, plunger, and sleeve assembly. In a normally closed valve, a plunger return spring holds the plunger against the orifice, preventing flow through the […]
Proper Valve Sizing Proper valve sizing is critical for controlling valve noise. An inappropriately sized valve 9308-618C can introduce noise issues. Emerson has standardized valve sizing techniques and selection criteria to account for factors that contribute to valve noise, so you can trust our products will work in your plant, as advertised. Exit Jet Independence […]

The solenoid valve is an industrial device that is controlled by electromagnetic force. It is an automatic basic component used to control fluids. It is an actuator; it is not limited to hydraulic and pneumatic. It is widely used in our daily life. First of all, we have a preliminary understanding of the solenoid valve. […]
The common rail technology refers to a kind of oil supply method in which the injection pressure is generated and the injection process is completely separated from each other in a closed loop system composed of a high pressure oil pump, a pressure sensor and an ECU, and the high pressure fuel pump delivers the […]
