Gasoline Direct Injection

Effects of Gasoline Direct Injection   Most modern cars are GDI, where fuel is injected directly into the combustion chamber. While efficiency and power are increased, the cleaning effect of fuel is negated. The result is carbon build-up. 


Carbon accumulates on the intake valves and creates an uneven surface for the valves to seat on, as well as taking up space which air would otherwise. Issues include, misfires, decreased power and efficiency, and pre-ignition.  


Effects of Gasoline Direct Injection   If a GDI vehicle has exceeded on year or 15,000 miles without a chemical treatment (BG GDI Service), the only solution to remove the carbon is to remove the intake manifold and perform a Walnut Shell Blast Service.
