Template:Infobox automobile engine The VK engine (formerly known as the ZH) is a V8 piston engine from Nissan. It is an aluminum DOHC 4-valve design.

The VK engine was originally based on Nissan's VQ V6 rather than the VH V8 used in previous Q45/Cima models. Changes include: a variable intake manifold, newly designed heads, and a larger drive by wire throttle chamber. The intake manifold directs air through different paths at different engine speeds to optimise low-end torque or high-end horsepower.

VK45DEEdit

The Template:Convert VK45DE was introduced in 2002 and is built in Yokohama, Japan. Bore and stroke is Template:Convert. Output is Template:Convert at 6,400 rpm with Template:Convert of torque at 4,000 rpm. Redline is at 6,600 rpm. It has an aluminum engine block and aluminum DOHC cylinder heads. It uses SFI, has 4 titanium valves per cylinder with Continuous Variable Valve Timing and features forged steel connecting rods, 4 one-piece cast camshafts, an unusual variable-flow induction system optimizes airflow for low- and high-speed operation, low-friction molybdenum-coated pistons, and a microfinished forged crankshaft.

MotorsportEdit

A flat-plane crankshaft version of the VK45DE was used by Nismo for Super GT races with the Nissan GT-R instead of using the GT-R's VR38DETT twin-turbo V6 engine.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The VK45DE was previously used in Nissan's 350Z Super GT car in 2007, replacing the previous VQ30DETT used in that car. In race trim, the Super GT VK45DE produces Template:Convert and Template:Convert of torque.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The engine idles at around 3,500 rpm and is restricted to the above specified power output. Without such restrictions, the engine is reputedly capable of producing nearly Template:Convert.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Nismo reasons that by using the engine, they eliminate turbo lag, save weight and generally prefer the torque curve of the atmospheric V8. Also in the Super GT series, an unbranded VK45DE is used for "Mother Chassis" cars; the engine is labeled the GTA V8.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

VK45DDEdit

The VK45DD is a Template:Convert V8 engine that is very similar to the VK45DE but adds a direct injection fuel system. This was Nissan's first V8 with direct injection (NEO-Di). It officially produces Template:Convert at 6,000 rpm and Template:Convert at 3,600 rpm, but it has unofficially over Template:Convert. It has a compression ratio of 11.0:1, and a bore and stroke of Template:Convert.

VK50VEEdit

The VK50VE is a Template:Convert V8 engine with Template:Convert at 6,500 rpm and Template:Convert at 4,400 rpm and redline is set at 6,800 rpm. Bore x stroke are Template:Convert and compression ratio is 10.9:1. The valvetrain is a dual overhead cam (DOHC) design with a continuously variable valve timing control system (CVTCS). The engine also features Nissan's VVEL valve timing technology.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}Template:Dead link</ref>

The VK56DE is a Template:Convert version built in Decherd, Tennessee. Bore and stroke is Template:Convert. Output is Template:Convert at 4,900 rpm with Template:Convert of torque at 3,600 rpm. It has aluminum-alloy block and heads and low-friction molybdenum-coated pistons. The valvetrain is a dual overhead cam (DOHC) design with a continuously variable valve timing control system (CVTCS) on the intake valves. It also has 4 valves per cylinder with micro-finished camshafts and ductile iron cylinder liners for increased durability.

MotorsportEdit

Nismo used the VK56DE for FIA GT1 racing in the Nissan GT-R GT1 from 2010 to 2011. In race trim, it produced Template:Convert and Template:Convert of torque.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

The Nissan Motorsport VK56DE was launched in Australia for the V8 Supercars Championship in 2013 by Kelly Racing in Melbourne. The engine has been reduced in capacity to Template:Convert to fit the V8 Supercars regulations. It has a bore and stroke of Template:Convert. It was fitted to a Nissan Altima version of the V8 Supercars "Car of the Future" specification that competed from 2013 until 2019.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Notes:

  • The Titan, Armada, and Pathfinder power figures are for regular 87 octane fuel. The Template:Convert Infiniti QX56 & Nissan Patrol are tuned for premium (91+ octane) fuel.
  • Some VK56DE powered vehicles are E85 capable.
