Diesel Fuel Injection Test Equipment

Diesel Fuel Injection Test Equipment

Although diesel fuel injectors perform using greater pressures than gasoline injectors, they are still prone to the same issues. Diesel fuels with low sulfur are actually more likely to cause issues with fuel injectors than regular gasoline. Having information on the equipment used to test for problems with a vehicles injectors can be beneficial to automobile owners.

Significance

    Fuel injectors can suffer clogging issues from deposits left behind from the diesel fuel. Heavy wear, as well as leaks, are things for which vehicle owners should check. Diesel fuel also fails to provide proper lubrication, which can cause the fuel to not flow though the injectors as smoothly as it should.

Pyrometer

    One type of test equipment that can be used to check diesel fuel injectors is called a digital pyrometer. Each engine cylinders temperature is revealed when using a digital pyrometer, indicating the specific cylinder thats not up to par. Low temperatures in one cylinder often means a problem with fuel injection.

Ohmmeter

    Another type of test equipment used for checking fuel injectors in diesel engines is an ohmmeter. The ohmmeter tests the resistance of glow plugs as their resistance rises according to engine temperature. Because of this, a low glow plug resistance reading means no heat is being produced from a particular cylinder. This in turn can indicate injector issues.
