(Not repairable – Discard fuel Injector) Test leaking Fuel Injectors.

What causes a fuel injector to stop delivering fuel?

An injector becomes clogged with fuel varnish deposits and fails to deliver its normal dose of fuel when it’s energized, or. Fuel pressure to the injector drops below specifications because of a weak fuel pump, plugged fuel filter or leaky fuel pressure regulator.

What causes wear and tear on fuel injectors?

Driving a car hard, combined with short start stop journeys, will increase the wear and tear on injectors. Letting the engine cool down, before shutting it off, will increase the lifespan of the injectors. This will also, benefit the rest of the engine too.

What happens to the fuel injector in a Yanmar Diesel?

Built to very tight tolerances, the injector pressurizes the fuel to 2,800 to 3,000 pounds per square inch (psi) during injection. High engine hours can wear the injector and reduce output pressure. Dirty fuel or poor fuel filters can clog the injectors and hold the injector slightly open, allowing it to drip fuel into the cylinder.

What causes a common rail injector to lose lubrication?

Those deposits could be from dirty fuel, or potentially created by the extremely high pressure, high temperature and fine clearances of the common rail circuit. Some 80-90% of the fuel is just used for cooling the injectors, and is continually recirculated, resulting in loss of lubrication and poor injector response.

What does fuel enhancer do to rail injectors?

Some 80-90% of the fuel is just used for cooling the injectors, and is continually recirculated, resulting in loss of lubrication and poor injector response. CRD Fuel Enhancer restores pristine cleanliness and strong lubrication to maintain precise injector response.
