Although its test capacity and function are slightly inferior to large machines, it can still meet the basic testing needs. In addition, it is an economical and practical choice.
Multifunctional Common Rail Injector Testing Machines
These machines combine multiple functions, such as injector testing, cleaning, and repair. They can perform various operations on a single machine, saving time and cost. The multifunctional common rail injector testing machines are suitable for workshops with limited space and require multiple functions. In addition, they can improve work efficiency and service quality.
The following are some of the specifications of common rail injektor testers:
Fuel Type
Petrol and diesel engines need different types of fuel. Therefore, the injector testers also use different types of fuel. The fuel used by the tester should be the same as that used by the engine to get accurate results.
Pressure Range
The pressure range is the minimum and maximum pressure the tester can measure. Different engines have varying injector pressure levels. Therefore, the common rail injektor tester should have a wide pressure range to work on various engines.
Flow Rate
The flow rate is the amount of fuel that the injector sprays into the engine. It is measured in cubic centimeters per minute. Like the pressure range, the flow rate differs depending on the engine type. Therefore, the tester should accurately measure different flow rates.
Gas and Liquid Standards
Injectors testers are required to meet certain standards when handling gas and liquids. They should be safe and not release harmful substances into the environment. Also, the liquids used in the tester should be protected from the environment.
Electrical Compatibility
Compatibility is important for the injector tester's components to connect and communicate. This ensures they work together and makes the process more efficient. The electrical system of the car should also be compatible with the common rail injektor tester.
Ease of Use
Common rail injektor testers should be easy to use. They should have clear displays and be lightweight and portable for convenience. Also, the testers should be simple to set up and take down.
It is important to maintain common rail injector testers for efficiency and accuracy. Here are some of the maintenance requirements:
Cleanliness
It is important to keep the injector tester clean to prevent contamination. Dirt and foreign particles can damage the injectors and affect the accuracy of the results. Therefore, it should be cleaned regularly and stored away from dust.
Check for Leaks
Users should check the injectors and all the tubes for leaks. Even a small leak can cause loss of pressure and affect the flow rate. This can lead to inaccurate test results. In case of a leak, the tester tubes should be replaced immediately.
Calibrate
Over time, the measurements of the common rail injektor tester may vary. Therefore, it needs to be calibrated regularly to ensure it measures accurately. The frequency of calibration is dependent on how often it is used.
Check the Battery
The common rail injektor tester requires a fully charged battery to operate. Users should check the battery level regularly and charge it before use. Also, the battery connections should be clean and tight to prevent power loss.
Follow the Manufacturer's Instructions
Different common rail injector testers have different maintenance needs. Therefore, it is important to go through the user's manual and follow the manufacturer's instructions for maintenance.
There are several factors to consider when buying a common rail injection test machine for resale or business. First, think about who the target customers are. Will it be car owners or repair shops? If it's for repair shops, consider buying larger injectors, as they will be more useful to the clients.
Also, look for a vehicle diesel injector tester with multiple functions. It should be able to test, clean, and calibrate fuel injectors. The machine should also have a coding function for new generation common rail diesel injectors. Machines with multiple functions will be more attractive to potential buyers.
When buying the tester, check the specifications to ensure it can handle the most common diesel injector problems. It should have a high flow rate and pressure to test the injectors effectively. Look for a model with a digital display, as it will be easier to read the results. Consider the size and weight of the machine, as well as common rail injektor tester connection fittings. Small and lightweight machines are portable and easy to handle. Finally, think about the budget. Only buy what can be afforded while still giving good returns on investment. It might also be wise to compare several models before making the final decision.
Many of the tools for testing fuel injectors, including the petrol injector cleaner gun, are available at auto parts stores. As a result, vehicle owners can conduct these tests themselves. When purchasing an injector cleaning kit, make sure it has all the necessary components, such as:
There are two main methods for cleaning fuel injectors: using a cleaning kit and using a machine. The machine method is more common and effective. Here's a step-by-step guide on how to use an injector cleaning machine:
Prepare the vehicle
Check the vehicle's manual and understand the fuel injector system. Turn off the engine and open the hood. Locate the fuel injectors, which are usually found near the engine block.
Connect the cleaning machine
Start by disconnecting the fuel line from the gas injectors. Then, connect the cleaning machine to the fuel injector ports. Ensure the connections are tight to prevent leaks.
Set up the cleaning solution
Fill the cleaning machine with a suitable cleaning solution. This solution should be compatible with the vehicle's fuel system. Follow the manufacturer's instructions for the correct dosage.
Start the cleaning process
Turn on the cleaning machine and start the engine. The machine will inject the cleaning solution into the fuel system while the engine runs. This process usually takes about 30 minutes.
Monitor the process
During the cleaning process, monitor the machine's gauges and the engine's performance. If everything is okay, the cleaning solution will break down carbon deposits and other debris in the fuel system.
Finish the cleaning process
After the cleaning solution is finished, turn off the machine and disconnect it from the fuel injector ports. Reconnect the fuel line to the fuel injectors.
Test the vehicle
Start the vehicle and let it run for a few minutes. This will allow the cleaning solution to circulate through the fuel system. Take a test drive to ensure everything is okay.
