Your diesel engine has several essential parts, but one of the most critical components is the fuel injection system. This system is responsible for feeding fuel to the injectors, adjusting the fuel quantity, adjusting injection timing, and atomizing the fuel. So, when something goes wrong with that fuel injector, your whole engine will suffer.
Knowing the signs that something is wrong will help you schedule semi-truck repairs that much sooner. Here are some signs that something is wrong with your semi-truck fuel injector:
The Engine Misfires
If you try to turn on your engine and it misfires instead, the engine is not getting enough fuel spray. A misfire can happen both when you try to fire up the engine or while it is idling. When it does, the engine might stumble or lose speed. Either way, don’t leave the problem as is. The risk is that your engine can overheat and lead to even more costly problems and diesel fuel injector repairs.
Rough Idle or Vibrating Engine
Another sign of fuel injector trouble is an idling engine that drops below optimal levels. If it drops too low, the engine will stall completely. If your engine vibrates, either when idle or driving, it can also mean trouble. When a faulty fuel injector is a cause, the corresponding cylinder cannot fire correctly. So, the engine vibrates after attempting to complete each cycle without fuel.
Smelling Fuel or Engine Surge
Have you noticed the smell of gasoline or fuel when you get into your vehicle? If yes, don’t start the engine or drive anywhere because it’s a sign of a fuel leak.
When it’s from a faulty fuel injector, fuel leaks out while the injector is idle. Another fuel issue can be that instead of the engine stalling, it surges instead. So when driving, watch out for a sudden surge and much slower acceleration.
Also, watch for the engine RPM changing rather than staying constant. These all point to a fuel injector spraying too much fuel into the engine cylinder. Either way, fuel troubles are a risk that you don’t want to wait to get semi-truck repairs.
Has the colour of your exhaust suddenly changed or taken on colour? While different coloured exhaust points to various issues, white smoke is a sign of a dirty emission. Clogged filters and injector deposits won’t be able to complete a total fuel burn. The dirty exhaust releases a puff of white smoke instead when that happens. You should schedule diesel fuel injector repairs as soon as possible if you notice coloured smoke.
