Template:Infobox automobile 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 Template:Cvt, Template:Cvt and Template:Cvt bore diameter.

78 mm series (2004–)

  • introduced in 09/2004 on Nissan Tiida C11 in Japan
  • three- and four-cylinder layouts, multi point fuel injection except HR12DDR and HR14DDe with direct fuel injection
  • most engines naturally aspirated with few exceptions being supercharged or turbocharged
  • No Daimler involvement

The HR16DE is a Template:Cvt naturally aspirated gasoline straight-4 engine, 16 valve DOHC; EFI; with variable valve timing. This engine has two fuel injectors per cylinder to improve fuel economy and reduce emissions. Bore: Template:Cvt; Stroke Template:Cvt. It produces Template:Cvt and Template:Cvt at 4000 rpm.
A new version (still 8 Cycle) has been released to equip Renault hybrids (E-Tech), it produces Template:Cvt at 5600 rpm and Template:Cvt at 3200 rpm.

In 2016, Nissan's skunkworks division, Autech, produced a limited run of Nissan March Autech Bolero models called the "A30", featuring an upgraded HR16DE engine. This hand built variant produced 150ps and 160N⋅m, with a redline of 7,100RPM. Upgrades included Autech camshafts, pistons, connecting rods, a new crankshaft, ported and polished intake ports, a freer flowing exhaust, an upgraded intake, and a re-tuned ECM. Only 30 examples were produced to commemorate Autech's 30th anniversary.

It is fitted to the following vehicles:


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.[6][7]
