Port fuel injection can offer better vaporization under certain conditions. But port fuel droplets can drop out of suspension when they hit the intake valve before entering the combustion chamber. Direct fuel injection is better at cooling the combustion chamber and controlling fuel trims under certain conditions. But, under certain engine speed and load conditions, direct injection can produce soot due to a lack of vaporization. Under some circumstances, port fuel injection will provide more torque.
