Understanding Carbon Build Up

 

You have heard that your vehicle has a direct injection engine. Direct injection means it’s spraying fuel directly into the engine’s combustion chamber rather than into the intake tract. It is a faster and more efficient way to get fuel into the cylinders, which ultimately leads to better fuel economy and cleaner emissions.

With benefits come consequences, and by spraying this fuel into the combustion chamber, your vehicle loses the ability to burn off carbon on the back of the intake valves – unlike older model vehicles spraying fuel into the intake tract. The carbon from the EGR (Exhaust Gas Recirculation) and PCV (Positive Crankcase Ventilation) systems usually find their way back into the engine to be re-burned. However, if this happens without fuel spray to help decarbonize, you are left with a build-up. That is where carbon cleaning comes in.

There are plenty of reasons to get this build-up removed. If you are experiencing some of the symptoms mentioned above, we highly recommend bringing your vehicle into our facility to be diagnosed by a professional. There are many parts in your vehicle’s engine that can share symptoms when in need of service. Pulling the vehicle apart to perform a carbon cleaning at your first sight of a misfire may not be the solution to your problem.

The best maintenance is always preventative maintenance, so carbon cleanings should be done around 60k miles for the first time, but build-up varies based on driving conditions.

 

What is involved in a carbon cleaning?

 

Removing the intake manifold is the most thorough way to clean the build-up off the valves. By removing the intake manifold, you can gain access to the valves, treat them with penetrant, manually scrape, walnut blast, and vacuum out the debris.

Leave it to the professionals 

Removing your vehicles intake manifold can be very involved, so carbon cleanings are best left to the professionals!

Incorrectly plumbing vacuum lines on your vehicles intake manifold, damaging a valve, or leaving something loose can all leave your vehicle running worse than before.

Because this service is so involved, Excelerate has made tools specifically for this service! Specialty tools like this ensure your vehicle is taken care of as best as possible.
