Is the 2011 Mustang 3.7 L V6 direct injected or merely sequentially port injected?

    The write ups on this engine offer contraadictory facts. When discussing the great fuel mileage they mention direct injection. In other discriptions they say the fuel in inject across the back of the valve. Who really knows the answer?

    its injected at the back of the valves. They "consider" it direct inject due to the fact that they do not spray in the runners at all.

    Not really. Diret injection within the combustion chamber would require injectors to stand up to combustion pressure and temps. Not a reasonable idea for a reliable mass production vehicle.

    It's port injection. I pulled the top apart a few weeks after getting the car. The injector bosses are in the lower intake manifold in the runners but are aimed a little better to improve fuel economy. That said, it's not even close to DI.

    If you look at the injector sockets on the rail in the pic you can see they angle towards the heads pointing the injector at the intake valve. This design allowed Ford to get the MPG they wanted out of the V6 without driving the cost of the car up.

    Direct injection is quite common on mass produced cars. Most BMWs and Audis have had it for years, GM has been using it since 2004 and Ford Introduced it on the EcoBoost engines a couple of years ago and last year the NA 2.0 in the Focus received direct injection. Mazda's Skyactiv technology on the 3 is direct injection.
