Direct-Injection System (Accord, Civic, CR-V, Fit, Odyssey, Passport, Pilot and Ridgeline)



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.
