Direct-Injection System (Select Vehicles)

What’s the Benefit?

Enhanced power output and fuel efficiency36 result from this technology.

The Feature:

Direct injection is a significant advance in induction design.

  • Traditional multi-port fuel-injection systems mix fuel and air in the engine’s intake ports before they enter the combustion chamber.
  • With direct injection, fuel is sprayed directly into the combustion chamber.
  • DI promotes a desirable “tumble motion” in the intake charge, promoting better combustion and higher overall fuel efficiency.
