Have you ever wondered how your car knows exactly when and how much fuel to send to the engine?  

That's the job of the injectors, those little champions of precision that bring your engine to life.  

What are injectors used for?

Petrol injectors are small but particularly important devices in a car, as they supply the engine with the perfect amount of fuel at the right time.  

They play a fundamental role in the performance and efficiency of internal combustion engines.  

This high-precision component is responsible for spraying fuel into the combustion chamber, enabling optimal combustion that directly impacts the vehicle's power, fuel consumption and emissions.  

In short, petrol injectors are like conductors who precisely control the amount of petrol so that the engine runs at its best, with more power, lower fuel consumption and less pollution.  

How does it work?

A pump draws up the petrol and pushes it hard so that it reaches the injectors. The car's computer sends a small electrical signal to the injectors to tell them when to open and how long to stay open, in order to release just the right amount of fuel. Once open, the injectors spray the fuel in tiny particles, much like a perfume atomiser, so that the fuel mixes perfectly with the air in the engine.  

This simple method ensures that the engine gets exactly what it needs to run smoothly, without wasting fuel or polluting too much.  

Why is this important? 

Better fuel atomisation allows the engine to achieve more complete and efficient combustion.  

The result: it generates more power with each cycle, which translates into quicker acceleration, faster engine response and improved overall performance.  

These power gains are often noticeable as soon as the injectors are replaced or cleaned.  

In summary:  

  • The finer the fuel is sprayed, the better it mixes with the air. The result? Combustion is super-efficient; your engine gets more power and runs better.  
  • The less fuel you waste, the more you save and the less you pollute.  
  • A well-fuelled engine also ages better and requires fewer repairs.  

Maintaining your injectors pays off in the long term

Fuel economy and reduced emissions 

An engine that burns fuel more completely consumes less. Well-maintained or upgraded injectors therefore reduce fuel consumption, which is a significant economic advantage. In addition, this optimised combustion reduces pollutant emissions into the atmosphere (unburned hydrocarbons, nitrogen oxides), making the car more environmentally friendly and compliant with current standards.  

A longer-lasting, high-performance engine

Perfectly functioning injectors reduce carbon deposits and other residues in the combustion chamber. This limits premature wear and tear on engine components, preventing potential breakdowns and extending the vehicle's lifespan. This maintenance is therefore also an investment in mechanical durability.

Clean, protect and save. Petrol additives that really make a difference. 

Maintaining your injectors:

To maintain optimal performance, regular maintenance of the injectors is recommended.  

This involves using specialist additives to prevent clogging, as well as professional cleaning in the event of deposits.  

Proper maintenance ensures lasting gains in power, economy and engine cleanliness.  

For example, you can use our Injector Cleaner for Petrol Engine every 3 fill-ups to keep your engine in top condition.  

Your petrol injectors are not just accessories, but key components that directly influence the power, fuel consumption, emissions and longevity of your engine. Choosing the right injectors, maintaining them and upgrading them if necessary, will allow you to unlock your vehicle's maximum potential.
