The 1.6-liter Nissan QG16DE engine (or QG16 for short) was produced from 2000 to 2013 and was installed on many popular models of the concern, mostly in the version for developing countries.
The 79 kW QG16DE engine with two camshafts has four valves per cylinder. The engine camshafts are driven by a chain. The cylinder block of the QG16DE engine is a single casting that forms the cylinders, a cooling jacket, the upper part of the crankcase and five crankshaft bearings made in the form of crankcase baffles. The block is made of special ductile iron with cylinders bored directly into the block body. The engine main bearing caps are machined with blocks and are therefore not interchangeable.
The QG family also includes internal combustion engines: QG13DE, QG15DE, QG18DE and QG18DD.
The engine was installed on:
- Nissan Almera 2 (N16) in 2000 – 2006;
- Nissan Almera Classic (B10) in 2006 – 2012;
- Nissan Bluebird Sylphy N16 in 2000 – 2006;
- Nissan Primera 3 (P12) in 2001 – 2008;
- Nissan Sentra 5 (B15) in 2000 – 2006;
- Nissan Sunny Neo N16 in 2000 – 2005;
- Renault Scala in 2002 – 2013;
- Samsung SM3 2 (L38) in 2002 – 2013.

Disadvantages of the QG16DE engine
- Dips in traction appear due to stretching of the timing chain, it serves about 150,000 km;
- Engine speed usually floats due to contamination of the throttle or EGR valve;
- A rather small resource has a generator belt and only a replacement helps it;
- There are no hydraulic lifters here, so the valves require periodic adjustment;
- Cases of destruction of the catalyst are described, the crumbs of which were drawn into the cylinders.
