Now, I don't everything about this, but the latest issue of "Car and Driver" brought this to my attention. There is a "Tech Tidbit" discussing dual injection. This is a design that is credited to being the brainchild of Toyota. It is a combination of port and direct fuel injection, hence "dual." "Direct injection offers superior mixture control and part-throttle cylinder filling, but port injection provides more time for the fuel and air to mix. The direct injectors operate all the time; port injection supplements during low engine speeds and loads" (direct excerpt taken from the "Car and Driver" September 2012 issue). This system is equipped on the 2.0 liter flat-four found in the Toyota/Scion FR-S and Subaru BRZ. This sounds pretty cool. However, I would like to hear others' comments. Good or bad... I figured some might like to hear about this.
