VVT-i vs Dual VVT-i car engine, which one do you think is better? Yups, this time we will discuss the engine technology favored by Daihatsu and Toyota manufacturers, namely VVT-i and Dual VVT-i. For those of you users of the Daihatsu and Toyota brands, you must have often heard and seen this technology term. Both the VVT-i or Dual VVT-i writings are also written on the engine of the two brands' vehicles. But do you already know the function of both? What are the advantages? How much influence does it have on the car you use? VVT-i technology itself is short for Variable Valve Timing with intelligence. Where VVT-i is a system to regulate the work of the electronic valves and the emissions that come out as efficiently as possible. The VVT-i system replaces VVT technology, introduced in 1991 in the 4A-GE 5-cylinder engine.
That way, fuel is more efficient and environmentally friendly without sacrificing performance.
When it was used on Corolla derivative cars, including the Toyota Celica. Meanwhile, most of Toyota's products currently use Dual VVT-i technology. Even LCGC cars such as the Toyota Calya and Toyota Agya have adopted it for a long time. The advantages of VVT-i engine technology is to produce a vehicle that is more powerful and more environmentally friendly. This is because there is an automatic adjustment in the intake valve or suction valve. Now to carry out all these functions, VVT-i is assisted by three main components. First, the electronic control unit (ECU) is in charge of ordering the IN valve optimally based on engine speed. The second is the oil control valve (OCV) which functions to control the hydraulic pressure on the orders of the ECU, and the third is the VVT control which functions to change the motion of the intake valve or the intake valve using hydraulic pressure. While the difference with Dual VVT-i, of course, is in more modern technology. If on the VVT-i there is only one equator, namely the suction valve. While the dual VVT-i there are two, namely the intake valve and exhaust valve. These two components work independently, by correcting and releasing. The correction in question is by adjusting the engine speed and the load on the car so as to produce an optimal torque curve at each revolution. That way, fuel is more efficient and environmentally friendly without sacrificing performance. Of course the performance of the Dual VVT-i engine is much better than the VVT-i. There are many advantages of Toyota's Dual VVT-i engine.
One of them is optimal power so that acceleration feels more powerful and strong to go through rough terrain such as incline. Interestingly, this technology, even though the car becomes more powerful, remains fuel efficient. Because the Dual VVT-i technology regulates the entry and exit of fuel more carefully. Even when the engine is turned on, Dual VVT-i technology has set the valve opening time to work fully and adjusts the engine temperature. When the optimal temperature is reached, the valve opening time can be adjusted according to the engine speed so as to make it work more optimally. In essence, it can be said that Dual VVT-i is a refinement of VVT-i. So the engine performance is also definitely getting better and perfect. In Indonesia alone, Dual VVT-i technology was first used on the Toyota Corolla Altis in 2010. In its development, not long after that Dual VVT-i was also used in high-performance car engines.

Like the 2GR-FE 3.5-liter V6, which the Toyota Avalon used for the US market has adopted it. Even more interesting, both VVT-i and Dual VVT-i technology do not need extra care, you know. Although this technology is fairly 'smart' it is very easy to maintain. "In general, that is often encountered, there is no special treatment for these two engine technologies. Maintenance is carried out regularly as usual and changes the oil regularly," said Putera, a car mechanic in the Otista area, East Jakarta. He also said that the VVT-i's performance also depends on a healthy car electronic system, so this system must be considered. The first thing to do by keeping the ECU dry, if you wash the vehicle make sure this component is not exposed to direct water. The work of the ECU which regulates the performance of the engine, cannot be separated from receiving information. That is, when the engine does its work, the controlling ECU also receives information about the performance of the engine In addition, the performance of the ECU also affects the filter. A dirty filter will prevent the sensor from reading the engine's performance and risk damaging it. Furthermore, is the car's electrical system disturbed? Starting from corrosion of the battery terminals or wires that are starting to rot. The instability of the electric current in the vehicle is also will affect the ECU. ECU devices that are overloaded due to poor electric current are at risk of being damaged quickly. Thus a full review of VVT-i vs Dual VVT-i engine technology. Hopefully this review answers your curiosity about these two technologies.
Are you planning to buy an automatic car? Or planning to ride it in the near future? Maybe you already know that the way to drive an automatic car is different from the usual car, which shifts the gears manually. Automatic cars have automatic transmissions, where the automatic car gearshift system is designed to be able to move without having to step on the clutch pedal. Automatic transmission has two types of systems, both of which are also known to be simpler and easier, namely semi-automatic and automatic systems. This is How to Check Jakarta Number Plates, Easy! Even though it's automatic, it doesn't mean that driving an automatic type car is just playing the gas and brakes. You also have to be required to have a good feeling in measuring engine power because automatic cars also have transmissions that you can adjust depending on your needs. You will meet the automatic transmission lever with the code P, R, N, D, D3, 2 and L. If you are a new player in driving an automatic car, you are definitely confused by the letters and numbers that are rarely found. 9 Ways to Get Rid of Stickers on Motorcycles, Smooth Back Again!

Well, to help you recognize a dead car gear, Qoala will explain in full about automatic car gear, from how to drive it, the meaning and function of each of the codes above and other information you need to drive an automatic car through this review.
If it's your first time driving an automatic car, you may be a little confused about how to drive it. Especially if you are used to using a manual car, which has a different way of operating the gear from the automatic one. This is because you don't have to adjust the clutch or shift gear because it's done automatically. You just need to stop and go without shifting gears or playing the clutch. But if you are not used to having to be careful, you might get confused between the brake pedal and the pedal or the wrong way to use the automatic car gear. Not infrequently heard of accidents because they are not familiar with how to shift gears automatic cars that are not familiar. Therefore you must know some important things in how to drive an automatic car below. As a beginner you need to be careful so that the lever is always in the correct position. First before starting the engine, the lever position must be in the P position or in the N position. Do not position the lever in reverse or R, these positions are used to reverse. If the lever is in the R position, the car will not start when it is started.
When you enter the key, do not immediately start the engine. You should wait for the needle to spin until the indicator is active or lit which indicates the electricity is ready. Some types of automatic cars provide an indicator in the form of sound when the car is really ready to be started. When first starting, it is recommended to step on and hold the brake pedal for safety reasons because you are afraid that the car will suddenly accelerate forward. Some automatic cars have an automatic procedure that keeps the engine running if you don't press the brake pedal, although some don't. When the engine is on and you want to start moving, the first step that needs to be done is to change the gear position of your automatic car which was originally in position P or N, to position R to go backwards or D to go forward. It is important to depress the brake pedal at the same time as moving the lever in gear. This method can prevent damage to the machine. The transmission lever aka gear or automatic car gear is an important component that affects the speed of the car.

Riding mode or driving mode is present as a supporting feature in automatic cars now with varied choices. You can choose the mode that suits your needs, one of which is the economic mode. This economical mode is suitable for those of you who want to drive an automatic car more relaxed. If you want to go at a higher speed, you can choose the sport mode. This mode will set the car engine to maximum performance. There are still several more types of modes offered, please learn and use as needed. Automatic cars are also usually equipped with manual mode. Even though it's called manual, it doesn't mean you will operate it the same as a non-matic car. That's roughly how to drive an automatic transmission car alias matic. It's actually simpler and more practical than the manual one, but if you're not familiar, it takes time to adjust. Especially from the transmission side which uses different codes. Not only numbers that indicate the order of teeth as in manual cars, but the shape of the teeth of automatic cars also uses a code in the form of letters to indicate their respective functions. What are the codes and their functions? Let's move on to the next discussion. As already mentioned a little above, in general, the transmission lever is marked with letters and numbers, namely P, R, N, D, 2, and L. This is standardly applied to various brands, be it in Xpander automatic car gears, gear shifters Honda Jazz automatic car, Ayla automatic car gear and even Avanza automatic car gear.
