Injector Cleaner for Petrol

The average motorist in the UK fills up with petrol around 17 times every year. That translates to around 650-700 litres. As all of this fuel has to be mixed with air for combustion in the cylinders, the fuel injectors or carburetors have to be maintained properly.

How do fuel injectors work?

Modern cars are fitted with fuel injectors as it is easier for manufacturers to control emissions, fuel consumption and power created from the engine.

The fuel injector is designed to regulate the quantity of fuel that is piped into the engine for combustion and is controlled by the ECU. Each cylinder has its own fuel injector to control the volume of petrol. The injector valve opens multiple times per second to allow pressurised petrol into the combustion chamber.

To make the fuel as efficient as possible, the fuel injector nozzle is designed to atomise the petrol into a fine mist so that the petrol can burn easily in the combustion chamber.

How do carburetors work?

Where fuel injectors are controlled by the vehicle’s ECU, carburetors are a mechanical part of the engine. Essentially, the carburetor is connected to the throttle and when the throttle pedal is pressed harder, more air and more fuel is then pulled in and sent to the cylinders. This means more power and speed.

As fuel injection is easier to control and monitor, fuel injection is fitted to nearly all modern vehicles.

However, gumming and carbon residues can cause blockages in the fuel delivery system- whether fuel injection or carburetor.

When this happens, the efficiency of the engine will be impaired. Lower power output will be paired with lower fuel economy and higher exhaust emissions.

MOTUL Injector Cleaner Petrol has been designed to remove the carbon residues causing blockages in the fuel injection system or carburetor and prevent micro-particles from sticking further down the fuel system.

This is particularly important with petrol vehicles that are fitted with a Catalytic Converter as an inefficient engine can cause blockages within the emission reduction system.

Recommended Use

Maintaining the efficiency, smooth running and performance of a petrol engine is not a one-bottle fix. Injector Cleaner Petrol is recommended as part of the range of fuel system cleaners from MOTUL.

When cleaning a car or van, it is recommended to start at the top and work down. This makes sense, as spraying dirt from the bottom of the car upwards will create more work. Although it cannot be seen, the principle is the same when cleaning a fuel system.

Starting with the injectors, following with a clean of the fuel system and then preventing or removing clogging from the catalytic converter. Once this process has taken place, maintaining engine efficiency and reducing spontaneous combustion or preignition with an Octane Booster will maintain and extend the life of the fuel system.

Each fuel additive should be poured into the fuel tank prior to the car being fully filled with fuel.

Repeated use of fuel system cleaners and fuel performance boosters will provide the maximum efficiency and results.
