FUHRER 319 Cleaner - Diesel Injection

Injectors, which are responsible for injecting fuel so it mixes with air and are located in the intake manifold, as we know, suffer wear due to use and accumulated dirt. They therefore require maintenance to prevent failure or replacement in the event that they have worn out significantly and no longer perform their function. The mission of the injectors is to introduce a small amount of fuel and direct the spray so that the fuel disperses evenly throughout the combustion chamber, so that the engine receives the correct amount.

There are facts we should know about this matter:

• Vehicle fuel is not pure — it usually carries residues that, over time, remain in the filters. If these are not cleaned with adequate frequency (every one hundred thousand kilometres the first time, and every fifty thousand thereafter), the residues pass to the injectors, which, when blocked, stop working and, in the long run, the engine fails.

• Oil companies, especially the large ones such as Repsol, Petronor, and Shell, add cleaning additives (anti-carbon and anti-varnish detergents) to all their fuels. Their aim is to eliminate impurities that clog tanks in tanker trucks and fuel pumps.

• Companies that lower the price per litre of fuel save on cleaning additives. In the long run, continuous use of fuel without these liquids damages the injectors. If you want to save money, it is better to alternate the use of cheaper fuel with higher quality fuel; your car's engine will thank you for it.

• Periodic inspection of the fuel filter is a preventive habit to avoid having to clean the injectors.

• Poor driving habits damage the car's engine; accelerating on start-up, warming up the car from cold, etc. are habits that are very unhealthy for our vehicle because they generate excessive carbon deposits.

Usage Tips

1. Fill the vehicle's fuel tank completely (this is important insofar as an excess of cleaning liquid can affect the engine and cause the car to run poorly or stall).
2. Pour an entire bottle of injector cleaner into the tank.
3. Drive your car normally and do not refuel until the tank is on reserve or nearly empty. This ensures that an optimal mixture is obtained; refuelling too early alters the mixture ratio and does not clean the injectors properly; furthermore, as the fuel tank empties, the injector cleaner will also be able to clean the deposits that remain at the bottom.
