Nissan HR engine

The HR is a family of straight-3 12-valve and straight-4 16-valve automobile engines with continuously variable valve timing, involving development by Nissan (Aichi Kikai) and/or Renault, and also Mercedes-Benz in the case of the H5Ht/M282. The designation of H engine is used by Renault, and M28x by Mercedes-Benz, to classify the family. There are three basic specifications of engine involving variations in engine architecture, or all-new architecture, with 72.2 mm (2.84 in), 75.5 mm (2.97 in) and 78 mm (3.07 in) bore diameter.

DE engine updates (2006–present)

edit

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.[6][7]
