What Does VTEC Stand For?

Whether you are looking to buy a VTEC engine or if you are simply trying to figure out what the term means, it’s important to understand what it is before you can make an informed decision. In this article, we will explore what a VTEC engine is, how it works, and some of the features you should be aware of when considering purchasing one.

Variable timing

A variable timing engine is one of the latest gizmos to hit the automotive industry. Although it has been around for a while, the most recent variants boast the best of both worlds: improved performance, boosted torque and low fuel consumption. The VVT system in question – which is incorporated into the two-cylinder Testastretta DVT engine – offers the benefits of independent control of both the intake and exhaust camshafts. It also boasts a plethora of performance and safety features to ensure that you get the most out of your ride. In addition to these features, the engine is a full Euro 4 compliant marvel.

One of the most exciting aspects of the new VVT technology is its ability to tweak the camshaft to achieve just the right amount of lift and compression to maximize power output. This is all thanks to the intelligent software system which is able to calculate the correct valve timing from a series of sensors to ensure that the engine is in tune with the driver’s needs.

Taking the concept of variable valve timing to its logical conclusion, the most prestigious motorcycle manufacturer in the game, Ducati, has developed the first motorcycle engine to feature the aforementioned technology. As part of this swoop and squat, the company has created the world’s first Desmodromic Variable Timing engine, which uses a number of valve-timing adjusters incorporated into the cam pulleys. These features also make it possible to maximise the engine’s performance and efficiency across the board.

While the engine’s most important role is to deliver maximum power at the right times, it is also important to have a smooth and dependable fluid delivery. For this reason, the variable timing technology comes with a host of safety and performance features including the electronically actuated switch – the aforementioned VTEC – which retards the intake cam for better power at different RPMs. Other safety features include a dual airbag system and the optional ABS, which utilises a programmable control unit to reduce the risk of injury in the event of a crash.

There’s no denying that the VVT engine has given a significant boost to the torque and power output of the Testastretta DVT, which has been the benchmark for Italian motorcycles since the model’s launch. Moreover, the technology has been embraced with open arms, as evidenced by the number of new models on the road, despite the lagging global economy.

Variable lift

Variable lift VTEC (VVT) is a technology that allows the engine to adjust the amount of lift it puts out for airflow through the intake valves. The idea is to improve drivability while reducing emissions and fuel consumption. A good example of VVT in action can be found in the Fiat Barchetta’s 1.8 liter engine which provides 90% of its peak torque between 2,000 and 6,000 rpm. In addition to the standard two-lobed VTEC, Honda has also implemented a 3-stage system for some models, which opens the intake valves slightly at 2500-3000 rpm.

The best VTEC systems implement multi-length runners and a synchronized timing belt. These allow for more sophisticated camshaft phasing and valve timing. Another advantage of VTEC is its ability to take into account the pressure of engine oil to optimize the valve timing and lifting for maximum performance. This is particularly important in the higher RPM ranges where power can be lost to airflow and turbulence.

VTEC also features an impressively simple to use dashboard display which displays critical information such as engine oil pressure and ignition switch settings. Unlike conventional systems, it offers a wide range of possible combinations. When using the more advanced versions, it can even automatically select and execute the best combination for each drive mode and engine condition. It is also one of the most cost-effective systems available and is a worthwhile investment for the average driver. As mentioned above, it also uses the latest technology to optimize cylinder fuelling and cylinder balancing for maximum horsepower and torque.

The most impressive part of this technology is that it uses the same basic hardware for all cylinders, making it an ideal candidate for a retrofit. With its cleverly designed and crafted valve timing and phasing schemes, it also allows the engine to deliver a broad range of output from low-RPM to high-RPM. While most cars of its ilk feature a relatively flat torque curve, the VTEC’s patented twin-spark design ensures that each cylinder is able to deliver its fair share of horsepower. On top of this, it is one of the more efficient four-cylinder engines available.

Amongst the many technologies available to the automotive enthusiast, VTEC stands out as the most unique and innovative. Compared to other CVTs, it offers a much smaller torque spread and a lower stalling rate. For this reason, it is well suited for high-performance street cars such as the Honda Civic and CRX 1.6i-VT. Moreover, it is one of the most refined and technologically advanced VTEC systems available and can be adapted to a variety of engine spec, including the aforementioned 2.4l K engine. Thus, it is easy to see why it is the envy of the competition. Hence, it is no wonder that its price has been slashed to almost half of its former glory.


The Honda i-VTEC engine is one of the most technologically advanced engines available on the market today. It is also one of the more fuel efficient engines. This technology provides cleaner performance, better fuel economy, and a smoother power band.

VTEC is a technology used in many different types of Honda and Acura vehicles. It is an electronic control that controls the timing of the intake and exhaust valves. When the engine reaches certain RPM ranges, it will adjust the intake and exhaust valves to provide a more efficient and effective drive.

The i-VTEC system was designed by Honda engineer Ikuo Kajitani. He created this system to improve efficiency and power. In addition, the i-VTEC system uses two different camshaft profiles, which allows the engine to produce more power and fuel economy. There are also versions of the i-VTEC system with direct injection.

The VTEC system was first introduced in 1989 in Japan. It was introduced on the B16A and B16B Integra XSi, and the NSX. It was developed to improve the volumetric efficiency of four-stroke engines. A wider, higher point on the cam lobe produces more lift, which increases the amount of power that the engine can produce. However, most of the torque offered by the VTEC was below its peak torque.

Unlike standard VVT systems, which only change the valve timing, VTEC controls the intake and exhaust camshafts independently. It is also capable of controlling valve overlap, which helps to increase the power of the engine.

Unlike the original VTEC system, the i-VTEC system is more sophisticated and includes tighter computer integration into the engine’s valvetrain mechanism. By changing the size of the cam, the size of the intake and exhaust valves, and the duration of the fuel-air mixture passage, the i-VTEC system is able to optimize the engine’s performance.

i-VTEC is a very powerful engine that can offer a great range of performance, but it has some disadvantages that may be noticeable for long periods of time. One of these is that it may be too complicated to maintain. For example, it is a good idea to inspect your water pump periodically to ensure it is in proper working order. You will also want to maintain the heat in your engine. Keeping your car in good condition will also help it stay in tip-top shape.

i-VTEC is based on the Honda J-Series SOHC (Single-Octane, High-compression) engine. It is a hybrid of the traditional DOHC VTEC and VTC. Because the i-VTEC system is a mix of VTEC and VTC, it offers the best of both worlds.

Compared to its predecessor, the i-VTEC engine is designed to eliminate the need for a turbocharger. This saves money and reduces the maintenance required by the engine.
