Sequent Direct Injection 2.0 is a serial sequential multipoint gaseous injection system (or master & slave). As for the other Sequent systems, gas injection occurs into the intake manifold, whereas the petrol injection directly occurs into the combustion chamber. This approach allows having the same installation simplicity appreciated on the other systems, and can use the same mechanic components, with evident advantages in terms of components validity.
