2000Bar Automotive Common Rail Diesel High Pressure Tester Kit and Injector Pipe Blanks

2. High quality material: Made of high quality material, rust and corrosion resistance, longer service life.

3. Easy to carry: The use of plastic box packaging, small size, light weight, can be moved to the need to work at any time, saving time and effort.

4. Pressure-proof and dust-proof: When it is not needed, the measuring tool can be stored in a plastic box in time for dust-proof and pressure release.

5. Accurate measurement: The measurement results are accurate, the recycling is smooth, and the results can be quickly judged.

Engine cranking/running pressure test

Step 1- Connect the instrument to the high-voltage circuit of the vehicle.
The engine is running normally, showing the actual fuel pressure value.

Step 2- Locate the high-pressure line from the pump to the fuel distributor. If inaccessible, look for a line from the fuel distributor to the fuel injection valve.
- In the absence of a pressurized fuel system, cut off accessible high-pressure lines and connect gauges using M12 or M14 hoses.
- Ensure that all hose connections are secured before proceeding to the next step.

Step 3
- Connect the diesel bin (5) with the hose at the bottom of the meter. When the overpressure valve is activated, the bottle collects excess fuel, and if the vehicle does not start, it should still display a value of 300 bar.
- While the engine is running, carefully check for fuel leaks before proceeding to the next step. If there is a leak, turn off the engine and leave the system pressure free, then check that the valve is properly sealed, start the engine and check again for leaks.

Step 4
- Increase engine speed to ensure fuel pressure increases accordingly.
- Special check whether the engine reaches 300 bar when idling or starting. If this pressure is correct, the low pressure circuit will work properly and the high pressure pump will provide the minimum pressure needed to properly start the engine.
- If the pressure is correct but the engine does not start, the problem is not in the high pressure pump, but may be an electrical fault, fuel injector, etc.

Step 5
- If the pressure does not reach the required pressure, check the pressure at the high pressure pump inlet with a low pressure tester.
- If the pressure at the high pressure pump inlet is correct, check the maximum pressure of the pump.

Maximum pump pressure test

When the pressure is too low, the high pressure pump shuts off the third piston. They use only two pistons and have lower engine power requirements. When 600-700 bar is reached, the third piston is activated by a magnet.

Step 1- Connect the meter to the high-voltage circuit of the vehicle. This means that the engine cannot be started and the test is only carried out when the engine is running. The pressure should rise above 1050 bar, which indicates that the pump is working properly.

Step 2- Locate high pressure line from pump to fuel distributor. If inaccessible, look for a line from the fuel distributor to the fuel injection valve.
In a non-pressure fuel system, cut the accessible high-pressure line and connect the meter to the M12 or M14 hose. Insert blind plug at meter outlet. Make sure the hose is connected in place before continuing.

Step 3- Connect the diesel waste fixtures (5) with the hose at the bottom of the meter. When the overpressure valve is activated, the bottle collects excess fuel.

Step 4- Start the engine. The pressure quickly rose to over 1050bar. This means the pump is working properly. If the pressure value is low, it indicates that the pump or pressure regulator is faulty. Run pump pressure control tests to identify problems.

Note: A problem with the pressure sensor (located on the fuel distribution line) may send incorrect information to the PCmut, which will pass incorrect information to the pressure controller, causing the controller to open prematurely. This results in low pressure. Use the EOBD tool with real-time data and compare the actual pressure of the gauge with the measurement results of the EOBD tool.

Injector leakage test

Fuel injector tubes are designed for use with gauges and hoses.

When the pump pressure is less than 300bar, this test should be carried out; Vehicle will not start.By closing the injector tube, it is possible to determine whether the pressure loss is due to an injector failure (opening the injector).

Step 1- In the absence of pressure fuel, disconnect the high-pressure line from the injector and install the injector tube tube (4).

Step 2- Follow the steps above to measure the starting/running pressure of the engine.

Step 3- If the pressure increases, it means that at least one injector is leaking.
- To determine which injector is leaking, connect the injector pipe separately and repeat the test.
- If the pressure is still low, the pump or pressure regulator may be faulty.
