General car question, example Honda civic 2020, no mileage, automatic , no codes.
Hi all,
Most modern cars have GDI injection only like the Mazda and Honda. There seems to be only a handful with port injection. Then Toyota have both direct and port. Why are car manufacturers in favor of direct injection when its so hard to clean the deposit in the intake valve? Other than emission reason. Is there anywhere in the servicing booklet that says cleaning of intake valve for a Honda or Mazda? I want to purchase a Honda or Mazda but they only have direct injection.
What is your experience with GDI engines? Do they lose performance after 2 to 3 years due to carbon build up in the intake valve?
It all depends upon the GDI engine. For example, the Ford engines don't seem to get too much carbon build up. They're going to GDI because it gets better gas mileage and has more power. Columbus like Toyota that have some with both GDI and port. Of course make a very complex system that works great now but no one knows how working the future when it gets old
Thank you for your time Scotty. 🙂 🙂
