With port and direct gasoline injection, Bosch combines gasoline direct injection with gasoline port fuel injection. The reason for this unusual partnership is: combining two normally separate approaches for fuel injection creates one innovative system where the strengths of the partial systems perfectly complement each other. In this particular case, this leads to advantages in terms of fuel consumption and emissions – both under partial and full load. Each of the two partners lets the other take the lead when it is time to show their respective forte. Each injection system delivers its benefits in terms of fuel efficiency and the number of emitted particles (PN) under different operating conditions.
Gasoline port fuel injection shines with reduced friction losses in partial-load operation, while direct injection excels close to full load with its increased knocking limit. Combined, the systems provide an additional reduction in particle emissions – division of labor at its best.
But gasoline port fuel injection adds even more advantages to the beneficial partnership. With its good mixture homogenization, the system generates fewer particles, has lower noise levels and consumes less fuel in situations with low engine load thanks to its lower friction loss compared to direct injection.
