Every time a vehicle’s driver presses the gas pedal, they are controlling how much fuel and air the engine takes in. The pedal tells the throttle valve how much air to let in and the computer tells the fuel system how much fuel to deliver. These calculated amounts of air and fuel are typically mixed together before being sucked into the combustion chamber of an engine cylinder. There the spark plug ignites the mixture, producing the controlled burn that powers the vehicle. It’s important for the fuel in the vehicle to be as clean as possible.
HOW DO THEY PLUG?
Today’s fuel injection systems operate at optimum efficiency but only under very strict conditions and with microscopic tolerances. Even the smallest speck of dirt, carbon or other deposits can directly affect fuel delivery. The sophistication of these systems is at the heart of why cleanliness is vital, unless, that is, people have money to burn.
Deposits can also build on other delicate system components that will develop into problems. Thus, the intake manifold, valves, combustion chamber, EGR valve, O2 sensor and the catalytic converter should also be cleaned for the vehicle to operate at an optimum level. Deposits on these components will affect the engine’s performance, fuel economy, and emissions.
New vehicles today run as designed: they provide smooth and quick acceleration, great fuel economy, and plenty of horsepower. However, after 5,000 – 6,000 miles, these magnificent engines begin to lose that initial responsiveness and efficiency, and guess why. That’s right – an accumulation of fuel-related contaminants.
Scientifically Speaking, Why Do Deposits Form?
Fuel-related deposits form from a combination of gasoline additives, engine heat and driving habits. A high quality detergent gasoline may help control deposit formation, but the same gasoline also contributes to it. While these detergents work well in most cases, they can cause other problems in an engine, and it’s interesting to follow the dirt trail.
Here’s how it happens. After driving to work in the morning, you park the car and turn off the engine. The gas that remains in the injector tips, intake manifold and combustion chamber quickly evaporates due to residual engine heat. This is called “hot soak.” But not all of the components of the gasoline evaporate. The remaining components – the fuel additives – begin to oxidize. This creates gums and resins that will collect any solids from the combustion chamber or airborne dirt that finds its way into the manifold through the PCV and EGR systems. These minute deposits continue to build up after every engine shut-off until they begin to affect the performance of the engine.
Since the opening of a fuel injector is no larger than the diameter of a human hair, it doesn’t take very long for these deposits to build up and begin restricting the fuel delivery and the spray pattern of the injectors. These deposits also build up in the intake manifold, on the back of the intake valves, inside the combustion chamber, on the O2 sensor and also in the catalytic converter. Airflow is also affected, and a 15% reduction in fuel and airflow can result in a 50% loss in power. That’s 50%!
Fortunately, here are solutions (literally) for all of these fuel-related problems due to deposit build-up — a professional fuel system service like the one Als Quick lube offers. It’s the only way to go to ease the pain of pricey petrol. Clean up the system, restore a vehicle’s optimum operating efficiency and give you a shot at holding on to a little more of your hard-earned money.
What does the two stage Fuel System Cleaning Service do?
Performing the two stage fuel system cleaning service:
The service helps clean the fuel system and combustion chamber with multistage cleaners.
Why is it important?
The fuel filter is located on the line that brings fuel from the tank to the engine. The filter removes contaminants and particulates so fuel can flow to the engine smoothly and without obstruction. A clean, unclogged fuel filter can help prevent reductions in engine performance.
What is the service?
The old fuel filter is removed and replaced with a new one that meets your manufacturer’s recommendations.
