The GDI (Gasoline Direct Inject) fuel and air induction service is specifically catered to GDI engines, which aim to provide greater power in a smaller engine.
It was standard that a 4-cylinder engine had excellent gas mileage but not a whole lot of power. Meanwhile, a V8 engine had a huge amount of power but was a complete gas guzzler, so it wasn’t very cost effective.
GDI engines are made to combine the best of both worlds by providing the gas mileage of a 4-cylinder engine with the power of a V8 engine. This is done by taking a 4-cylinder engine, adding a turbo, and running it like a diesel, making it the most powerful and efficient car currently available.
Of course, nothing is completely perfect without proper maintenance and care.
The problem that GDI engines encounter most often is a build up of carbon on injectors. They are constantly subjected to the harsh environment of the combustion chamber, causing them to quickly clog up with carbon and misfire.
In the advancement of the GDI engine, the injectors were placed where fuel does not get the opportunity to wash over the intake valves to prevent carbon build up.
GDI Fuel and Air Induction Service
This is where the GDI Fuel and Air Induction Service comes into play.
It is recommended to have this service performed every 15,000 miles, though it can be done earlier because carbon can start to build up as early as 3,000 miles. The induction services is done by a BG certified mechanic and they work to clean the areas that carbon has built up.
The process is as follows:
- BG 44k is poured into the gas tank as a cleanser that will continue to run through the engine until your next gas fill up.
- Two 11oz cans of GDI Intake Valve cleaner are poured into the BG VIA — this is the machine that runs the actual cleaning process.
- The solution is sprayed into the intake with the Air Intake Cleaning tool on the machine.
- A can of fuel injection and combustion chamber cleaner is then poured into the BG VIA.
- And the BG VIA is connected to the fuel rail and the fluid is sent into the engine.
Once this service is performed, the customer will notice quite an improvement in gas mileage, power, and a decrease in emissions. This service should be performed regularly in order to keep the GDI engine running smoothly and at peak performance.
