?? What role do injectors play?

A car needs very precise amounts of fuel and air to function properly. It is the injectors that inject this mixture into the engine to ensure good combustion. Thus, if your injectors are faulty, it can directly affect the performance of your engine as the air / fuel mixture is no longer processed correctly. Therefore, it is very important to properly maintain the nozzles to prevent clogging or complete clogging.

Here are some tips to help you avoid clogging your nozzles and increase their life:

• Choose good quality fuel: this greatly limits the pollution of your engine.

🔧 What are the symptoms of the HS injector?

There are several symptoms that can alert you to the condition of your injectors:

• Your car won't start: you turn the ignition key and hear the engine roar, but your car still won't start. Of course, your injectors cannot inject fuel and / or air into your engine, thereby preventing combustion.
• Excessive fuel consumption: you notice that your car is using more fuel than usual. This could be due to a faulty injector causing too much fuel to be injected into the engine. Likewise, this symptom can occur due to leaking injectors if cracked or broken.
• The smell of fuel in the cabin: If you smell fuel inside the car, it means that some of the fuel is not burning in the engine. This could be due to a damaged or faulty injector.
• Black smoke emissions: if the amount of fuel or air injected by the injectors is incorrect, combustion in the engine may be incomplete. This will result in a strong ejection of black smoke from your tailpipe.
• Loss of engine power: If you experience a loss of power while accelerating, it could be due to malfunctioning injectors.
• Overclocking jerks: If your injectors are clogged or dirty, you may experience engine misfire while accelerating.
• Fuel leak under the car: If you notice a spot of fuel under your vehicle, it could be due to a leak in the injectors.

If you experience any of the above symptoms, we advise you to quickly head to the garage to have your injectors checked before the malfunction worsens and increases your bill.
