Introduction to common rail system
As we all know, although there were already diesel passenger cars in the 1930s, the development of early diesel cars originated from the unique fate of the Soviet T-34 tank during World War II. Be easy to fire and be the best on the battlefield. The current Chinese market is like the early international market. When consumers talk about diesel vehicles, they often laugh and say, "The biggest advantage of diesel vehicles is that they will not catch fire." However, with the development of diesel technology, people are increasingly discovering the infinite charm of diesel engines: high torque, lo
What is a diesel injector assembly and how do they work
The injector assembly is a mechanical component that is part of the fuel system whose task is to introduce fluid (in our case fuel) into the vehicle's engine. Unlike a simple transmission, fuel injectors allow a gradual and calibrated flow of just the right amount of fuel to the engine to function properly. Depending on the type of operation (electronic, mechanical or mechatronic), syringes can have different names.
How to judge the failure of the plunger and the oil delivery valve couple?
How to judge the failure of the plunger and the oil delivery valve couple? When the diesel engine is working, loosen the high-pressure oil pipe joints of the fuel injection pump in turn. If a single pump does not produce oil or little oil, the speed and sound of the diesel engine will not change significantly, indicating that the plunger couple of the cylinder is or The plunger spring has failed. If the pump oil of each cylinder is normal, but there are still problems in operation, stop the machine, loosen the joint of the fuel inlet pipe of the fuel injection pum
IPARTS:The quality of customer service
Iparts provides customers with mad in china and various brands of injectors, nozzles, plungers, repair kits, control valves, head rotor, ECU ,sensors, testers, oil pumps, etc: Denso, Caterpillar-Perkins, Bosch, Delphi, Cummins, Siemens and unit injectors.
Precautions in safe operation of high pressure oil pump
1. Oil pumps and jacks should use specified oil grade working oil, generally No. 10 or No. 20 mechanical oil, and other hydraulic oils with similar properties can also be used, such as transformer oil. The oil poured into the oil tank must be filtered. It should be filtered once a month when it is used frequently, and the oil tank should be cleaned regularly. Generally, the oil level in the oil tank should be maintained at about 85%, and it should be replenished in time if it is insufficient. The oil added should be the same as the oil in the original pump. The oil temperature in the fuel tank
What are the key points for the use and maintenance of diesel generator injectors?
What are the key points for the use and maintenance of diesel generator injectors? Diesel generators should avoid long-term overload operation to prevent the body from overheating and causing the needle valve coupling of the injector to be stuck. For diesel engines that have been stored for a long time, the fuel injector should be removed and immersed in clean diesel oil to prevent the needle valve from being corroded and unable to open and close flexibly. The use and maintenance of diesel generator fuel injectors can be improved from the installation position of the fuel injecto
Common faults of electronically controlled common rail injectors
The fuel injector is a key part of the diesel engine, and its working quality directly affects the power, economy, emission and reliability of the diesel engine. According to the requirements of mixture formation and combustion, the fuel injector should have a certain injection pressure, injection stroke, and appropriate fuel injection cone angle. In addition, the fuel injector should be able to quickly cut off the fuel supply when the fuel injection needs to be stopped without oil dripping. Phenomenon. The components of the common rail system are sensitive to the water in the fuel syst
What are the important functions of the fuel injector to improve the overall performance of the fuel injector? As an important part of the diesel engine, the fuel injector, the plug, and the oil outlet valve are called the three precision parts of the diesel engine. When the electromagnetic coil is energized, suction is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is sprayed out at high speed through the annular gap between the needle of the needle valve head and the nozzle hole, forming a mist, so that the fuel is fully burned. The working c
Debugging Method of Fuel Injection Pump and Its Plunger Maintenance
Debugging Method of Fuel Injection Pump and Its Plunger Maintenance The fuel injection pump is an important part of the diesel engine and is regarded as the "heart" part of the diesel engine. Once it fails, the entire diesel engine will malfunction. The first thing to do is to debug the oil supply time. Remove all the oil outlet pipe joints, turn the dial to make the oil outlet of cylinder 1 start to emit oil, align the scale with an integer scale as the 0 scale, and turn the dial according to the working order. Observe whether the oil supply interval angle of each cylinder is 6
High pressure common rail technology details
What is common rail technology Common rail technology refers to a fuel supply method that completely separates the generation of injection pressure from the injection process in a closed-loop system composed of a high-pressure fuel pump, a pressure sensor and an ECU. The high-pressure fuel pump delivers high-pressure fuel to the public fuel supply pipe. Precise control of the oil pressure in the common oil supply pipe makes the pressure of the high pressure oil pipe independent of the engine speed, which can greatly reduce the variation of the oil supply pressure of the diesel e
5 minutes to let you know how to judge whether the injector is working properly
5 minutes to let you know how to judge whether the injector is working properly If the single cylinder fuel injector does not work, the engine operation will be unstable, the vibration will be excessive during acceleration, and the power will drop. If your engine exhibits the above symptoms, the fuel injectors need to be checked. If you want to know what happens when the injector doesn't work, you can use the "cylinder fracture" test method to judge: pull out the injector of a certain cylinder of the engine at the current speed, that is, if the cylinder does not w
In 2022, the global Diesel Injector market sales will reach 100 million USD, and it is expected to reach 2029 USD 100 million, with a compound annual growth rate (CAGR) of % (2023-2029). At the regional level, the Chinese market has changed rapidly in the past few years. The market size in 2022 will be US$ million, accounting for about % of the global market. It is expected to reach US$ million in 2029, and the global share will reach % by then. In terms of consumption, the region is currently the largest consumer market in the world, with a market share of % in
