If you have bought a Honda brand car after 2000, you have encountered VTEC, and if you have bought it recently, you have encountered the i-VTEC system. Let’s take a closer look at the curious questions such as VTEC and i-VTEC, how they work, what are the differences, which allow you to get maximum performance from the engine even at the lowest and highest rpm.
The developments in the automobile market in recent years both surprise and excite automobile lovers. Although many different technologies have emerged in this rapid development process that started recently in the 2000s, the most popular ones are among them. Honda’s VTEC and i-VTEC systems it happened. VTEC is the first system made in this field, and i-VTEC is a system that has become smart with the help of technology in recent years.
VTEC and i-VTEC systems allow you to get the maximum efficiency from the engine even at the lowest and highest revs in Honda vehicles, but as you can understand from the slight change in their names, i-VTEC is smart and much more successful than its predecessor, in line with today’s technology. Bride What are VTEC and i-VTEC, how do they work, what are the differences Let’s see the details you need to know about these systems by examining the frequently asked questions in detail.
What is VTEC?
Variable Valve Timing and Lift Electronic Control, in Turkish, Variable Timing Valve Control System, in short The VTEC system was first introduced in 1989. introduced. This system, which is used in the DOHC engine of the Honda Integra XSi model, became indispensable for many Honda models until the 2000s.
So what is i-VTEC?
Intelligent Variable Valve Timing and Lift Electronic Control, developed by Ikuo Kakitan, in Turkish, Intelligent Variable Timing Valve Control System, in short It was first introduced in 2001 with the i-VTEC system. we met. Since then, we have started to encounter i-VTEC in all Honda models with many different equipment.
What does VTEC and i-VTEC do?
VTEC and i-VTEC systems, with their simplest definition, even at the lowest and highest speed They ensure maximum efficiency from the engine. The camshafts in the engine that control the air passage are multiple in these systems. These shafts increase engine performance by activating according to the number of revolution minutes referred to by the abbreviation RPM.
What is the difference between VTEC and i-VTEC?
The main task of VTEC and i-VTEC systems is the same, to achieve maximum performance at the lowest and highest rpm. Original VTEC system through two different profiles provided performance control. The first profile controlled fuel efficiency at low rpm, while the second profile offered stable performance at high rpm.
Since the original VTEC system was more effective at high rpm, it was upsetting the fuel efficiency. If i-VTEC even at much lower rpm intervenes and takes over the case. Since it offers two basic camshafts, it provides maximum performance by intervening instantly according to the number of revolution minutes referred to by the abbreviation RPM.
How does the Honda i-VTEC work?
Let’s examine it through an example; Although it is impossible on an engine without i-VTEC system, let’s say you start the car and you are driving at 10 – 15 RPM. The valves controlled by the camshafts provide air flow. and the pistons should work. However, this operation is almost impossible at such a low RPM. It is possible to give a similar example for high rpm.
In these examples, the engine may come to a shutdown point due to the camshaft. In the i-VTEC system, Compatible with both low speed and high speed Since they have camshafts, the valves and pistons will always provide the correct flow, no matter what rpm the vehicle is running.
The original VTEC system didn’t help much in terms of fuel economy when turned on after 5500rpm. However Because the i-VTEC system can operate at much lower revs it manages to offer the performance and torque power needed by the drivers in the most accurate ratio.
Importance of the i-VTEC system:
The i-VTEC system is built-in in the engines of many Honda models released in recent years, and keeping up with the developing automobile technology It provides the needed fuel efficiency with the help of different systems. Therefore, the i-VTEC system is extremely important and necessary.
If the Honda model you are using has an original VTEC system, not an i-VTEC system, it is possible to change it. If you switch to the i-VTEC system, your engine performance will definitely increase. Considering the gasoline prices, it seems very logical to save money by increasing fuel efficiency with the i-VTEC system.
It provides maximum performance at all revs in Honda vehicles. What are VTEC and i-VTEC, how do they work, what are the differences We answered the frequently asked questions and talked about the details you need to know about these systems. If you are using VTEC and i-VTEC systems, you can share your experience in the comments.
