DE engine updates (2006–present)

Changes include:

  • neutral idle control achieved through the coordinated control of the engine in tandem with the XTRONIC CVT
  • introduction of alternator regenerative control mechanism
  • Reduction of engine friction by machining the cam shaft to a crowning mirror-like finish and application of a fluorine coating to the chain guide
  • Delayed valve closure timing of the intake, achieved through the increased conversion angle of C-VTC and superior timing management, thus reducing pumping loss when idling
  • Lower idling speed

The improved HR15DE engines were first used in Nissan Cube, Nissan Cube Cubic, Nissan Note, Nissan Tiida, Nissan Tiida Latio and Nissan Wingroad sold since December 25, 2006.[4][5]

gollark: Here's a picture of me capturing it.
gollark: I used applied energistics spatial IO to "borrow" the end exit portal and shove it in my basement, along with that end gateway in the background.
gollark: I made a self-sustaining baguette generator which also produces free energy, because Minecraft has none of that "conservation of matter" nonsense.
gollark: I really don't understand why they wrote their own serialization format personally.
gollark: Minecraft apparently has issues with NBT data growing too large.
