\"clogged<\/span><\/p>\n

If you drive a diesel vehicle long enough, you\u2019ll learn how it handles when its engine is in optimal condition. Over time, though, you might notice differences in the car or truck\u2019s performance. Numerous issues can cause changes in vehicle handling, but a clogged fuel injector is a common problem for diesel vehicles.<\/span><\/p>\n

You might not know <\/span>when a diesel engine overhaul is required<\/span><\/a>, but the guide below will help you identify warning signs of clogged fuel injectors. The expert diesel auto technicians from All Bay Diesel in Berkeley, CA, explain the most common signs of this diesel engine issue.<\/span><\/p>\n

How Fuel Injectors Work<\/h2>\n

Most newer diesel engines have fuel injectors. A fuel injector is a valve under electronic control that receives pressurized fuel from the fuel pump. It also sprays a fine fuel mist into the engine\u2019s cylinder through a nozzle to help the motor burn the fuel more efficiently.<\/span><\/p>\n

The combustion process relies on the right amount of fuel at the right time, pressure, angle, and spray pattern. The diesel engine\u2019s central computer or Engine Control Unit (ECU) controls the fuel injector\u2019s functions using sensors. When the ECU senses the engine\u2019s need for fuel, it relays the information to the injector.<\/span><\/p>\n

Debris from the fuel or fuel system can clog the injector. Though the fuel filter traps most impurities before reaching the injector, small amounts of contaminants and moisture can get inside it. Debris from corrosion or other impurities can jam the fuel injector if that happens.<\/span><\/p>\n

A skilled auto mechanic can address a clogged fuel injector by flushing the component. However, caked-on debris may require an ultrasonic cleaning or part replacement to keep the diesel engine running smoothly.<\/span><\/p>\n

7 Signs That Your Diesel Engine Has A Clogged Fuel Injector<\/h2>\n

Lower engine performance<\/h3>\n

Reduced engine performance often signifies a diesel engine has a clog in its fuel injector. The decreased performance results from insufficient fuel reaching the engine at the right moment, overworking the system. Your vehicle won\u2019t handle the same as it would with a fully functional fuel injector.<\/span><\/p>\n

You might also notice inconsistency with the RPM (revolutions per minute)<\/a> needle. When a fuel injector has a clog, the needle on the tachometer tends to move unpredictably. For instance, it might jump unprompted, alerting you to RPM changes when your vehicle isn\u2019t shifting gears.<\/span><\/p>\n

Rough idling<\/h3>\n

Since your diesel engine isn\u2019t receiving enough fuel, you might notice the RPM dropping below ideal levels when idling the vehicle. This issue results in a rough idle, which means your car or truck might shake or sputter when it\u2019s running but not moving.<\/span><\/p>\n

In most cases, rough idling comes with engine stalling. A stalled engine usually occurs if the RPM drops too low or suddenly. If that happens, you will need to restart the vehicle.<\/span><\/p>\n

Reduced fuel economy<\/h3>\n

Your fuel economy will worsen when you force your diesel engine to overwork with a clogged fuel injector. The engine isn\u2019t receiving the appropriate amount of fuel for its combustion. As a result, it will add stress to the injector to get additional fuel.<\/span><\/p>\n

A poor fuel economy results from the truck\u2019s Engine Control Unit thinking the engine needs excessive fuel when it doesn\u2019t. If you find yourself filling up at the gas station more often, the issue could be a clogged fuel injector.\u00a0<\/span><\/p>\n

Engine vibrations<\/h3>\n

Your diesel engine might emit gentle movements when running. However, you shouldn\u2019t feel abrupt or violent vibrations while driving. If your car or truck develops a vibration issue, it could be a dirty or damaged fuel injector not allowing its cylinder to fire correctly.<\/span><\/p>\n

If your vehicle has this issue, you might notice the engine vibrating or hiccupping as it completes each cycle.<\/span><\/p>\n

Engine turnover problems<\/h3>\n

Sometimes, vehicles won\u2019t start when the engine has a faulty fuel injector. If the component can\u2019t deliver fuel to the engine\u2019s cylinder, it can\u2019t initiate combustion using the proper air and fuel mixture.<\/span><\/p>\n

Consequently, the engine might not turn over. A dirty fuel injector can cause engine failure that prevents a vehicle from starting in rare cases.<\/span><\/p>\n

Engine misfire can be caused by a clogged fuel injector<\/h3>\n

People often attribute bad spark plugs to engine misfires. However, a faulty fuel injector can also cause this problem. The engine can misfire if a clogged fuel injector doesn\u2019t spray enough fuel into the engine. This misfire disrupts the ideal air-to-fuel ratio for combustion.<\/span><\/p>\n

An engine misfire means a car might sputter, stumble, or lose RPMs. As you drive a vehicle with a misfiring engine, you will feel vibrations throughout the car. You might also feel the engine pause momentarily after stepping on the gas pedal.<\/span><\/p>\n

Fuel leaks and odors<\/h3>\n

A dirty fuel injector or one with a deteriorated seal can develop a fuel leak. If that occurs, your engine won\u2019t receive enough fuel through the component\u2019s nozzle because it will drip from the injector\u2019s body.<\/span><\/p>\n

You can visually inspect the injector to detect signs of fuel on its exterior or fuel rail. You might also smell unburned fuel inside your truck cabin due to a leak.<\/span><\/p>\n

Other issues can generate a fuel odor like a faulty sensor or damaged fuel lines. So, it\u2019s best to schedule an auto inspection to determine the issue\u2019s cause.<\/span><\/p>\n
