3.5 L Duratec engine fuel injection

Post by daveya48187 » Wed Nov 06, 2019 10:08 pm

Is my 2016 3.5 L duratec engine direct fuel injection? or does the fuel spray on the intake valves? have learned about the danger of carbon buildup on the valves of direct fuel injection engines and wondered if it will be a problem in the future.

Cant confirm if it's direct injection through the internet alone, but seems that most likely is.

As for carbon buildup, most likely your 2016 comes with dual complete injection systems. One to provide fuel directly into the cylinder for normal operation, and the other is a conventional port injector for cleaning the valves with fuel to prevent carbon buildup.

The Ecoboost is direct injection, the N/A is not.
