It is fitted to the following vehicles:

DDR series[edit]

The DDR series include direct injection and supercharger.

HR12DDR[edit]

Nissan HR12DDR

The HR12DDR is a 1.2 L supercharged straight-3 engine. It produces 72 kW (97 hp) and 143 N·m (105 ft·lbf). Designed for small-car applications, this gasoline engine incorporates a variety of technologies to minimize CO2 emissions while providing practical levels of power output.[2][3]

Some of the pertinent features are:

  • Compression ratio of 13:1
  • Continuous Variable Valve Timing Control System (CVTCS)
  • Direct Injection Gasoline (DIG)
  • Miller cycle
  • Supercharged
  • Variable capacity oil pump
  • Hydrogen-free diamond like carbon(DLC) coated valve lifters and piston rings
  • Sodium filled exhaust valves
  • High efficiency

It is fitted to the following vehicles:

DE series[edit]

The DE engine series include naturally-aspiring engines.

HR12DE[edit]

The HR12DE is a 1.2 L straight-3 engine. It produces 59 kW (80 PS; 79 hp) and 108 N·m (80 ft·lbf).[2]

Bore : 78.0 mm (3.07 in) ; Stroke 83.6 mm (3.29 in) ; Capacity : 1198 cc; 12v DOHC

It is fitted to the following vehicles:

HR15DE[edit]

HR15DE installed in 2004 Tida Latio

The HR15DE is a 1.5 L (1498 cc) straight-4 engine, output is 100 PS (74 kW; 99 hp) @ 6000 rpm and 139 N·m (103 ft·lbf) @ 4000 rpm.

Bore : 78.0 mm (3.07 in) ; Stroke 78.4 mm (3.09 in) ; Capacity : 1498 cc

It is fitted to the following vehicles:

HR16DE[edit]

Bore : 78.0 mm (3.07 in) ; Stroke 83.6 mm (3.29 in) ; Capacity : 1598 cc

It is fitted to the following vehicles:

DE engine updates (2006-)[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.[4][5]
