Carbon buildup in Gasoline Direct Injection engines

What causes carbon buildup in Gasoline Direct Injection engines What is Gasoline Direct Injection? Gasoline direct injection (GDI) can cause carbon buildup problems. It differs from traditional multiport fuel injection (MFI)in several ways. First, the tip of the fuel injector is located right in the combustion chamber, so the injector is subjected to very high compression and combustion pressures. That’s different than an MFI injector that’s located in the intake manifold and subject to only manifold vacuum. An MFI injector is coil driven and releases fuel at approximately 50 to … Read More
