CVVTCS
Continuous Variable Valve Timing Control System (CVVTCS) is an automobile variable valve timing technology developed by Nissan. It is also used in a twin CVTC configuration on engines like the Nissan Juke's MR16DDT engine. CVVTCS is the successor to Nissan's earlier valve timing implementation NVCS.

Variable Valve Timing
In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems. Two-stroke engines use a power valve system to get similar results to VVT. Background theory The valves within an internal combustion engine are used to control the flow of the intake and exhaust gases into and out of the combustion chamber. The timing, duration and lift of these valve events has a significant impact on engine performance. Without variable valve timing or variable valve lift, the valve timing is the same for all engine speeds and conditions, therefore compromises are neces ...

Automobile
A car or automobile is a motor vehicle with Wheel, wheels. Most definitions of ''cars'' say that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people instead of cargo, goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Ford Model T, Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced Draft animal, animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the Developed country, developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nissan Juke
The is a subcompact crossover SUV (B-segment) produced by the Japanese car manufacturer Nissan since 2010. Debuted as a production vehicle at the 2010 Geneva Motor Show in March and positioned below the C-segment Qashqai, it was introduced to North America at the 2010 New York International Auto Show to be sold for the 2011 model year. The second-generation model was revealed for the European market in September 2019, offering larger dimensions by utilising the newer Renault–Nissan CMF-B platform. The second generation marks the withdrawal of the model from most markets outside Europe and Australasia to make way for the Nissan Kicks. The name " juke" means to "dance or change directions demonstrating agility", and is also derived from the word "jukebox". First generation (F15; 2010) On 11 February 2009, Nissan announced that the model would go into production at the Nissan Motor Manufacturing UK (NMUK) plant in Sunderland, United Kingdom, during 2010 following its ap ...

Nissan MR Engine
The Nissan MR engine family consists of straight-four 16-valve all-aluminium automobile engines with variable valve timing co-developed by Renault and Nissan. Renault calls it the M engine. Other noteworthy features of this engine family include acoustically equal runner lengths and a tumble control valve for the intake manifold, a "silent" timing chain, mirror finished crankshaft and camshaft journals, and offset cylinder placement in an attempt for increased efficiency. The MR engine family features 'under stress' manufacture, meaning while the block is being bored, a torque plate puts the block under stress. The block becomes temporarily distorted until the head is torqued onto it, at which point the block is pulled into the correct shape. __TOC__ MR16DDT (Renault M5Mt) The MR16DDT is a DIG-T ( Direct Injection Gasoline-Turbocharged) inline-four 16-valve engine, with a bore x stroke of . It was first introduced in the Nissan Juke small SUV in the autumn of 2010. Outpu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N-VCT
Nissan Variable Timing control or Nissan Valve Timing Control System (commonly known as N-VTC, VTC, NVCS or NVTCS) is an automobile variable valve timing technology developed by Nissan. N-VTC was first introduced in 1987 on the VG30DE and VG20DET engine. 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 the sprocket. Valve to crank angle timing varies depending on whether engine speed is high or low and changes at fixed intervals. NVTCS is hydraulically actuated similar to Honda's VTEC system, but adjusts a different aspect of the valve train, so it is more like the I part of I-VTEC. NVTCS equipped Nissan engines do not have as high of engine speeds as VTEC equipped engines so NVTCS is sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Variable Valve Event And Lift
Nissan Variable Valve Event and Lift (commonly abbreviated as VVEL) is an automobile variable valve timing technology developed by Nissan. 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). VVEL variable valve timing is also used in the VK50VE V8 engine from the Infiniti FX50. A rocker arm and two types of links open the intake-valves by transferring the rotational movement of a drive shaft with an eccentric cam to the output cam. The movement of the output cam is varied by rotating the control shaft with a DC stepper motor and changing the fulcrums of the links. This makes the continuous adjustment of the amount of the valve's lift (e.g., the amount of intake opening), during the intake valve event in the four-stroke cycle, possible. CVTC and VVEL together control the valve phases and its valve events, allowing free-con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
