    Nissan Variable Valve Event and Lift (commonly abbreviated as VVEL) is an automobile variable valve timing technology developed by Nissan.. Nissan VK50VE Engine. Nissan VVEL was first introduced to the US market in late-2007 on the 2008 Infiniti G37 Coupe sporting the new "VVEL" VQ37VHR engine (VQ37VHR motor specs: 11.0:1 CR, 95.5mm bore, 86mm stroke, 7500rpm redline).

    en.wikipedia.org/wiki/Variable_valve_lift

    Nissan introduced its Variable Valve Event and Lift (VVEL) in 2007 as the world's second CVVL system. The first application was on the VQ37VHR V6 engine of Skyline Coupe (Infiniti G37). Nissan's system is more compact than BMW’s, involving fewer parts and less energy loss, and is therefore more adaptable to high-performance engines. [7]

    Nissan Ecology Oriented Variable Valve Lift and Timing (commonly known as VVL & VVT) is an automobile variable valve timing technology developed by Nissan. VVL varies the duration, and lift of valves by using hydraulic pressure switch between two different sets of camshaft lobes. VVT varies the valve timing throughout the RPM range.

    Nissan/Infiniti VK56VD Engine. The VK56VD is a 5,552 cc (5.6 L; 338.8 cu in) 32-valve, DOHC, Direct Injection Gasoline aluminum-alloy V8 and features Nissan's latest VVEL (Variable Valve Event & Lift System). The direct injection system provides better wide-open throttle performance and improved fuel economy and emissions performance by ...

    Many standard DOHC Nissan engines featured Variable Valve Timing, such as the VG30DETT, and as such do not use the "V" designation. The "V" designation is applied only if the engine has variable valve lift. A good example of an engine where not all of the feature designation spots are used is the L28ET engine. The two features listed are ...

    A VQ35DE in a 2007 Nissan Maxima Cylinder head of VQ35DE. The 3.5 L (3,498 cc) VQ35DE is used in many modern Nissan vehicles. Bore and stroke are 95.5 mm × 81.4 mm (3.76 in × 3.20 in). It uses a similar block design to the VQ30DE, but adds variable valve timing for the intake. It produces from 231 to 304 PS (170 to 224 kW; 228 to 300 hp) of ...

  8. N-VCT - Wikipedia

    en.wikipedia.org/wiki/N-VCT

    N-VTC varies valve timing by rotating the affected camshaft relative to the sprocket; valve lift and duration are not altered. This rotation is achieved when an electric solenoid, controlled by the car's ECU, allows pressurized engine oil to flow into and through the cam and into a slave mechanism, axially advancing camshaft timing relative to ...

  9. Variable valve timing - Wikipedia

    en.wikipedia.org/wiki/Variable_valve_timing

    Early variable valve timing systems used discrete (stepped) adjustment. For example, one timing would be used below 3500 rpm and another used above 3500 rpm. More advanced variable valve timing systems offer continuous (infinite) adjustment of the valve timing. Therefore, the timing can be optimized to suit all engine speeds and conditions. [2] [3]
