Newer cars have a direct fuel injection system which has a few advantages, compared to older (carburetor, fuel injection) systems. You get more power, faster throttle response and better fuel economy. However, this system is known for having one issue. It is known as carbon deposits.
Carbon deposits are made due to combustion processes, so they cannot be avoided. If you use a poor quality fuel, they will occur in even higher amounts. The main problem is when carbon deposits create large amounts on intake valves and ports. As the side effect, you will:
- Increased fuel consumption.
- Poor performances.
- Clogged ports (up to 60-70%).
- Slower throttle response.
- A lower top speed and slower acceleration.
- Increased risk of damaging the engine.
Obviously, all of these points affect the engine and cause additional issues. The main thing you should know that each car, older more than 3 years will have this problem! Luckily, there are 2 ways to clean the intake valves and get the full power of an engine.
This was the best way to clean carbon deposits and get the most from your car. It involves removing the cylinder head and the valves. Cleaning is successful, but it is a time-consuming and expensive process. Also, there is a high risk of additional components that may be damaged during the process.
No matter which type of an engine your car has, it will need up to 20 work hours to be rebuilt.
This is apparently the newest and the best method to remove carbon deposits. According to the BMW Essex 99% of car owners noticed improvement after the process. It is simple because it includes injecting walnut shell particles into the car, intake system.
The particles will hit the carbon deposits and eliminate them. On the other hand, the mentioned particles are soft, so they cannot damage the metal inside the ports and around the intake valves. The best part is the fact this is an incredibly fast process and it is successful in most cases.
Don’t believe that if you have a car 3 years old that you don’t need this process. In a matter of fact, every single vehicle, older than 2 years should be treated with this process. Vehicles older more than 5 years definitely have carbon deposits and they may be up to 50%, which is severe and requires immediate attention.
