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 si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nissan VG Engine
The VG engine family consists of V6 engines designed and produced by Nissan for several vehicles in the Nissan lineup. The VG series was introduced in 1983, becoming Nissan's and Japan's first mass-produced V6 engine. VG engines displace between 2.0 L and 3.3 L and featured an iron block and aluminum heads at a 60° vee-angle. The early VG engines featured a SOHC arrangement with 2 valves per cylinder. Later versions featured a slightly different block, a DOHC arrangement with 4 valves per cylinder, and N-VCT, Nissan's own version of variable valve timing, for a smoother idle and more torque at low to medium engine speeds. The production blocks and production head castings were used successfully in the Nissan GTP ZX-Turbo and NPT-90 race cars which won the IMSA GT Championship three years in a row. Origins Development of the ''VG'' series began in 1979 by Nissan Machinery, a former member of the Nissan Group ''keiretsu''. The objective during development was to ...

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 ...

Nissan VVL Engine
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. Together they function similarly to Honda's VTEC system. The SR20VE is the most common engine with NEO VVL. There have been two main versions of this engine. The first version made and torque. This engine was used by Nissan from 1997 to 2001. It is found in the Nissan Primera, Nissan Bluebird, and the Nissan Wingroad. The second variant of the SR20VE is found only in the 2001 and later P12 Nissan Primera. This version of the SR20VE makes , and torque. This engine is commonly known as the SR20VE '20V'. Although, in automotive terms, '20V' would normally be interpreted as having twenty valves, this is incorrect. The name '20V' is the n ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nissan VE Engine
The VE engine is a piston engine, piston V6 engine from Nissan. It is based on the Nissan VG engine and was only used for the 1992, 1993, and 1994 model years. This engine has an iron block, aluminum cylinder heads with 4 valves per cylinder and dual overhead camshafts, variable valve timing on the intake camshafts, coil-on-plug ignition, and an available variable intake manifold (5-speed only). Additionally, the engine has a 10.0:1 compression ratio, a cylinder bore of 87.0 mm, and a piston stroke of 83.0 mm. A major difference between the VE30DE and the Nissan VG engine#VG30DE, VG30DE engine are the heads. The low under-hood clearance on the 1992–1994 J30 Nissan_Maxima#1989.E2.80.931994, Nissan Maxima demanded a special head to be developed with 30°, rather than 46°, between the valves. Lack of space also demanded a redesigned camshaft drive system, so a special chain drive was developed. The camshafts are driven by a single primary and two secondary chains. The engine ...

Automobile
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of 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 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced 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 economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more comple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
