Gas Direct Injection Cleaning With BG

Gas Direct Injection started to become popular with car manufactures about five years ago. It is popular because it offers higher performance out of the same size motor. It still gets good gas mileage without compromising power. It produces less harmful emissions better efficiency than the more popular port fuel injection engines. In order to achieve increased fuel economy and still have engine performance auto companies are increasingly combining gas direct injection, variable valve timing and low tension piston rings to achieve big power and smaller engine efficiency.

What this really means to you is all of this technology works great but needs maintenance attention sooner than some of the old cars did. The gas direct injection engines inject fuel into the hottest part of the combustion chamber. There is an ash or gunk that builds up on top of the valves that gets really hot and bakes on. These deposits build up and eventually cause a problem for the engine. When the deposits build up it can cause issues like misfires, reduced fuel economy and cause the check engine light to come on. Hydrocarbon deposits building up in the combustion chamber starts to cause the engine to choke when even a small amount of ash is present. This changes the ratio of fuel to air. This build up can also cause problems with injectors, stuck piston rings and PVC (positive crankcase ventilation) issues and even engine failure if ignored long enough.

Some engines can be cleaned with a chemical cleaners such as BG, injected into the fuel delivery system. If it is bad enough and has multiple symptoms it can become necessary to manually remove and clean the build up.
