QG18DEEdit
The Template:Convert 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 Template:Convert. 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.<ref>Nissan press release, November 20, 2000: http://www.nissan-global.com/GCC/Japan/NEWS/20001120_10e.html Template:Webarchive</ref>
