PFI injects at pressures up to 20 bar into the air intake system. The uniform mixture homogenization in the intake manifold results in lower NOx emissions. Moreover, port fuel injectors work in less demanding operating conditions and as a consequence, time to market is much faster.

DI injects at pressures around 30 bar directly in the combustion chamber using a low-pressure process. The power density is similar to that of a diesel engine. DI is particularly well suited for applications with high demands on dynamics and power density within a limited installation space, such as mobile construction machinery.
