The QG engine is a 1.3 L, 1.5 L, 1.6 L, and 1.8 L straight-4 piston engine from Nissan. It is a lean-burn aluminum DOHC 4-valve design with variable valve timing and optional NEO Di direct injection.

The QG engines were designed for Nissan by Aichi Machine Industry, Japan.

Nissan websites state the QG as standing for "Quality and Green".[1]


QG13DE[edit]

The QG13DE is an 1.3 L (1295 cc) DOHC 16-valve with 4-cylinder. It produces 87 hp (65 kW) at 6000 rpm and 130 N·m (96 lb·ft) at 4400 rpm. Bore = 71 mm; Stroke = 81 mm

It is used in the following vehicles:

QG15DE[edit]

Water-cooled straight 4 cylinder engine with 1.5 L (1497 cc) cubic capacity and DOHC control. Bore and stroke are 73.6 mm (2.90 in) and 88 mm (3.5 in). Output is 109 hp (81 kW) at 6000 rpm and 143 N·m (105 lb·ft) at 4400 rpm and later 105 hp (78 kW) at 6000 rpm.

This engine is used in:

Power outputs for N16 Almera:

  • '00-'03: 90ps
  • '03-'06: 98ps

QG16DE[edit]

The QG16DE is an 1.6 L (1597 cc) straight 4-cylinder engine with Double Over Head Camshafts with 16 valves. The cylinder head also features Nissan Variable Cam Timing (N-VCT) and micro-polished camshafts. A new water pump assembly has been designed for the QG16DE; the design is based on the water pump from the GA16DE, the changes made it more efficient and reliable than its predecessor. The engine produces 88 kW (118 hp)@6000 rpm and 165 N·m (122 lb·ft)@4000 rpm. Bore and stroke is 76 mm (3.0 in) and 88 mm (3.5 in).

QG18DE[edit]

The 1.8 L (1769 cc) QG18DE was designed for Nissan by Aichi Machine Industry, Japan. It is manufactured both in Japan and the Mexican city of Aguascalientes. Bore is 80 mm (3.1 in) and stroke is 88 mm (3.5 in). The engine is tuned to achieve most of its torque at low revs at the expense of raw power at high revs, making the engine very responsive in day-to-day driving. It has a cast-iron engine block, aluminum DOHC cylinder head, uses MPI fuel injection, forged-steel connecting rods, two single-piece cast camshafts and a cast-aluminum intake manifold. It also features N-VCT (Nissan's Valve Timing Control technology). This engine received the RJC Technology of The Year Award of 2001.[2]

Specifications

Emissions Control Devices

  • OBDII - Onboard Diagnostic System (codes can be read/erased by a variety of readers, e.g. Actron, blaZt). Nissan Pulsar N16 Models without EuroOBD in Australia do not have OBDII.
  • EGR - Exhaust Gas Recirculation
  • HO2S - (4) Oxygen Sensors (2 before exhaust catalyst, 2 after) - note a series 2 1.8l has only 2 O2 sensors: 1 pre-catalytic-converter and 1 downstream from it.
  • TWC - Three Way Catalyst (2 in exhaust manifold, 1 under car).
  • EVAP - Charcoal Evaporative Purge Canister.
  • Ignition Timing: 9 degrees BTDC (can be altered +/- 2 degrees using CONSULT-II handheld diagnostic tester, e.g. blaZt).
  • Knock Sensor - located on engine block; retards timing if pinging/detonation is detected.
  • Heated Throttle Body - heated by engine coolant.

The QG18DE is used in the following vehicles:

QG18DEN[edit]

The QG18DEN is the natural gas version of the QG18DE. It produces 105 hp (78 kW) @ 5600 rpm and 149 N·m (110 lb·ft) @ 2800 rpm. Bore and Stroke are 80 mm (3.1 in) and 88 mm (3.5 in). It was used in the Nissan AD van from 2000 to 2008.
