The QG engine is a 1295cc, 1497cc, 1597cc and 1769cc 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 by Nissan's Aichi Kikai division [1] in Japan.

Nissan websites state the QG as standing for "Quality and Green".[2]

QG13DE

The QG13DE is a 1295cc DOHC 16-valve with 4-cylinder. It produces 87hp at 6000 rpm and 1300NaN0 at 4400 rpm.Bore x Stroke= NaNmm

It is used in the following vehicles:

QG15DE

Water-cooled straight 4 cylinder engine with 1497cc capacity and DOHC control. Bore and stroke are NaN2NaN2. Output is 90hp at 5600 rpm and 1280NaN0 at 2800 rpm and later 105hp at 6000 rpm and 1430NaN0 at 4400 rpm.

This engine is used in:

QG16DE

The QG16DE is a 1597cc 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 880NaN0 at 6000 rpm and 1650NaN0 at 4000 rpm. Bore and stroke is NaN2NaN2.

Specifications

It is used in the following vehicles:

QG18DD

The 1.8 L direct-injection QG18DD produces 130hp at 6000 rpm and 1740NaN0 at 2800 rpm.

It is used in the following vehicles:

QG18DE

The 1769cc QG18DE was designed for Nissan by Aichi Machine Industry, Japan. It is manufactured both in Japan and the Mexican city of Aguascalientes. Bore and stroke is NaN2NaN2. 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 Multi-port 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.[3]
