In this video, I will demonstrate how to effectively clean intake valve deposits on gasoline direct injection (GDI) engines while addressing common questions about GDI technology. Key topics covered ...

The other day I dropped my car off at a European specialist shop, and while I was there, a technician was working in the engine bay of a Mk7 Golf R, cleaning out carbon deposits off the intake valves.

While carbon buildup happens on essentially all engines, gasoline, diesel, N/A, or boosted, it's an increased concern in GDI engines. Standard Electronic Fuel Injection features injectors higher in ...

While port injection is still the most common form of electronic fuel injection, gasoline direct injection is quickly starting to replace it since it provides better fuel atomization, decreased ...

Gasoline direct injection (DI) engines have been lurking in the shadows of gasoline-burning, internal combustion engine development for decades but are now becoming mainstream. This is all good, as DI ...

Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...
