Misfiring engines can cause serious problems for your truck. Below we explain why your semi's engine may be misfiring and what you can do to fix it. When you need diesel engine repair in Anaheim, CA, or the surrounding areas, call Orange County Fleet Services to get the job done right.
An engine misfire happens when one or more cylinders in your truck's engine fail to ignite the fuel-air mixture at the appropriate time. This disturbs the smooth firing sequence, resulting in anything from unsteady idle to a significant reduction in performance. The causes range from old spark plugs to malfunctioning ignition coils and dirty fuel injectors.
Misfires are most commonly caused by damaged spark plugs. These tiny but vital components are critical in igniting the gasoline-air mixture within the engine cylinder. When spark plugs get damaged or worn out, they struggle to deliver the necessary spark, resulting in misfires. Common signs of a broken spark plug include rough idling, poor acceleration, and even reduced fuel efficiency. Keeping your truck's engine running smoothly requires regular inspections and promptly replacing spark plugs.
Fuel injectors direct fuel into the engine's cylinders, ensuring efficient combustion. Over time, dirt, debris, and carbon deposits can accumulate on the fuel injectors, interfering with the precise fuel distribution required for best engine performance. When fuel injectors become dirty, the fuel-air combination is not optimal, causing misfires and other performance difficulties. Regular maintenance, such as using fuel system cleansers and keeping fuel filters clean, will help prevent deposits and keep your semi's engine running smoothly.
Ignition coils provide a high-voltage spark, igniting the fuel-air combination in the engine cylinders. When an ignition coil fails, it may produce uneven or weak sparks, resulting in misfires. Rough idling, slow acceleration, and reduced fuel efficiency are all signs of a malfunctioning ignition coil. Regularly inspect and repair broken ignition coils to prevent misfires.
