They do directly inject into the cylinder. They call it port injection. My 4.0L Jeep had six injectors, one for each cylinder. The injectors just don't inject at the top of the combustion cycle like a diesel does.

I thought that the port injection system still injected the fuel into the stream of air on its way to the cylinder before the intake valve.
