Prostream Fuel
System Services Fuel System Services

The services above address issues common to petrol and diesel engines. They remove built up carbon deposits in the induction system, throttle body, EGR valve and on the intake valves. In addition the Petrol Injector Clean and Decarb service cleans the injectors in petrol non-direct injection engines. The services also include an In-tank Fuel System cleaner to treat the fuel tank and the rest of the fuel system for any contamination and moisture. If you have any queries please contact our helpful team on 13 30 32

Why do it?

Carbon build up and contamination is not a case of “if”. It will occur In most petrol engines it is however a slow build up and takes time to affect the efficient operation of your car. As it happens slowly you don’t notice it’s affects.

In most diesel engines it is a progressive build up that accelerates over time also affecting the efficient operation of your vehicle, though quicker than a petrol engine. As it happens progressively it’s affects often go unnoticed. Excessive carbon build up affects how your engine “breathes” by restricting air flow into the engine and the proper operation of the throttle body. The choking of the airways your engine breathes through, a dirty throttle body and valve deposits will lead to issues such as poor throttle response, loss of engine power and increased fuel consumption.

By performing an Intake System Carbon Clean you will:

• Improve performance
• Improve fuel economy
• Smooth rough idle
• Lower emissions
• Reduce DPF (Diesel Particulate Filter) Regeneration Cycles (Diesel vehicles)

How does Carbon build up?

Carbon contamination in the induction system more of an issue than ever.

For petrol engines this is due to a number of factors:

• Engine design with direct injection petrol engines no longer “washing” valves and intakes as they inject the fuel directly into the combustion chamber.
• Extended service intervals
• Short trips and city driving.
• High exhaust gas recirculation flow rates to regulate the production of Nox (Nitrogen Oxides)
• Low viscosity engine oils that promote higher oil misting through the PCV (Positive Crankcase Ventilation) system
• Turbo charging systems that allow oil bypass through turbine shaft seals
• As carbon deposits form they attract more carbon, accelerating the process.

Diesel Engines rely on drawing in large quantities of air to operate efficiently, over time carbon deposits build up on the inner walls of the induction system due to emission control devices such as exhaust gas recirculation (EGR) valves sending exhaust gases and unburnt fuel back into the induction system. Also the use of low viscosity engine oils and sealed crankcase ventilation. Short trips and city driving also contribute to carbon build up. As carbon deposits form they attract more carbon, accelerating the process.

How often is an Intake System Carbon Clean needed?

• Every 60,000 km (30,000km for diesel) when your vehicle does mainly short trips/city driving
• Every 80,000 km (50,000km for diesel) when your vehicle does mainly long trips/freeway driving
• When you start to have poor fuel economy
• When you notice your vehicle is sluggish
• When your vehicle doesn't provide the power it used to
• When your vehicle doesn't idle well
