Honda created the VTEC (Variable Valve Timing & Lift Electronic Control) technology to increase a four-stroke internal combustion engine’s volumetric efficiency, which leads to better performance at high RPM and less fuel usage at low RPM. The VTEC system alternates between two (or three) camshaft profiles using hydraulic pressure. Ikuo Kajitani, a Honda engineer, created it. [1][2] It differs significantly from conventional VVT (variable valve timing) systems, which just alter the valve timings and make no adjustments to the camshaft profile or valve lift.

A VTEC engine: is it good?
Depending on how you drive, yes and no. The majority of drivers won’t notice their VTEC kicking in, but Honda automobiles with VTEC technology tend to be more efficient throughout a wider rpm range than many comparable vehicles, and they’re a lot of fun to drive in the appropriate circumstances. It only becomes operational when the engine is working at relatively high revs, which is uncommon under regular driving circumstances, especially if your vehicle has an automatic transmission. However, if you prefer driving on winding roads and you can adjust your own gears, VTEC makes a big difference.
What accomplishes a VTEC engine?
In essence, the VTEC system blends high-RPM performance with low-RPM fuel efficiency and stability. Additionally, the changeover happens smoothly, enabling consistent performance across the entire powerband. The engine computer manages the switching process between the two cam lobes.
What kind of engine is in a Honda VTEC?
The Earth Dreams Technology VTEC TURBO engine series, which was first presented in 2013, has innovative features such gasoline direct injection, turbochargers, Dual Cam VTC, and VTEC on the exhaust profile rather than the intake, putting an end to the “traditional sound” of VTEC in this engine. Turbo lag is eliminated thanks to the exhaust rocker arms’ VTEC application, which speeds up the turbo’s spooling. Three different displacements of VTEC Turbo engines are available: 1.0 liters for 3-cylinders, 1.5 liters for 4-cylinders, and 2.0 liters for 4-cylinders.
A 2-litre 4-cylinder turbocharged engine with Euro 6 emissions compliance was first deployed in European vehicles starting in 2015 with the Honda Civic Type R.

VTEC motors are they quick?
Honda developed the i-VTEC technology, also known as intelligent variable valve timing and lift electronic control, to reduce the amount of fuel used by Honda automobiles. The VTEC system switches between two camshaft profiles hydraulically.
The engine can effectively have numerous camshafts thanks to Honda i-VTEC. With this technology, however, the engine’s computer has the ability to vary the cam timing and activate different camshaft lobes as the engine passes through various RPM ranges.
The amazing aspect of this technology is that it allows for the simultaneous use of high- and low-speed camshafts in the same engine. The basic goal of Honda i-VTEC is to achieve maximum engine performance throughout the whole RPM range.
Which of Honda’s engines is best?
The 2001-vintage K is frequently seen in Honda’s sportier models, such as the Honda Civic Type R and Honda Accord Sport. This two-liter four-cylinder engine can currently produce 306 horsepower and 296 lb.-ft. of torque in the Civic Type R thanks to VTEC and a turbocharger. The Honda Accord Hybrid’s “Earth Dreams K24W” engine was named one of Ward’s 10 Best Engines for 2017.
The Civic Type R’s VTEC engine is the most potent street-legal Honda to ever make it to America, producing 153 hp/L.
The K series engine continues to have excellent Honda engine reliability, as is frequently the case. Common problems include oil leakage from the front crankshaft seals, camshaft galling on older engines, and excessive vibrations from worn engine mounts.
VTEC: Does it use more fuel?
When Honda’s R&D team reached the first milestone with the REV (Revolution-modulated valve control) valve stopping mechanism, the enormous effort of creating a smarter engine officially began. The system was designed to be able to shut down several valves at once in order to maximize airflow, provide stable idling, and improve smoothness for low- to medium-powered engine operation. The Honda CBR400F motorcycle used this brand-new advancement for the first time in 1983. Honda then set out to innovate the four-wheel drive after greatly improving the 2-wheelers.
Honda created the DOHC (Double Overhead Camshaft) VTEC system for autos from the REV used in motorcycle engines. A four-stroke internal combustion engine’s volumetric efficiency was increased by the DOHC VTEC, leading to stronger performance at high RPM and decreased fuel consumption at low RPM. The VTEC technology has completely altered the way the world views engines since it was originally introduced in 1989.
The VTEC engine made its debut in India in 2000 and has since established a legacy. The VTEC system had numerous upgrades over the years, with i-VTEC being the most significant (where “i stood for intelligent). The VTC (Variable Timing Control) and VTEC processes were combined in this technology to offer a very effective and excellent performance.
VTEC or turbo: which is superior?
While VTEC is more focused on extracting the maximum amount of horsepower from the engine because torque on VTEC cars can only be felt on the VTEC range, which is anyplace after 5,500RPMs, the torque produced by a turbo is still negligible in comparison.
VTEC – similar to a turbo?
The term “analog” describes turbochargers. They offer varying degrees of boost, from none to full boost. When exhaust gases are passing through a turbocharger, which happens whenever an engine is operating, the turbocharger is always active. According to the position of the wastegate and the rate at which exhaust gases are passing through it, it produces boost linearly. In contrast to VTEC, a turbocharger delivers varied quantities of boost across a large RPM range rather than abruptly “kicking in” at a specific RPM.
A “digital” device is VTEC. At the engagement point, there is a sharp transition and change in engine performance and sound because it is either on or off. Depending on the model and if the intake and exhaust systems have been adjusted, the degree of VTEC engagement can be felt or heard varies. If I’m paying careful attention, I can feel and hear it engage at 5,500 RPM in my standard Ridgeline.
Imagine turbochargers as a lamp with a dimmer control; the light can be anywhere from off to full brightness.
Consider VTEC as a light that has a straightforward on/off switch. The light has only two settings: off and full brightness.
A VTEC is it a turbo?
Under any circumstance, from city driving with frequent stopping and starting to highway travel, the VTEC TURBO engine is fuel-efficient. A 2.4L normally aspirated engine has a lot of torque for city driving due of its size. Due to its turbo, the VTEC TURBO engine has higher torque than the 2.4L normally aspirated engine. A 1.5L engine may perform on par with a 2.4L engine thanks to the VTEC TURBO technology.
Summary
Utilizing a turbocharger, direct injection system, and variable valve timing mechanism, Honda’s VTEC TURBO technology efficiently utilises every last drop of fuel.
Honda aims to mix driving pleasure with environmental performance with VTEC TURBO and hybrid technologies.
Honda stopped utilizing VTEC when?
The 2017 Honda Civic Si will include a turbocharged engine, which is a first for the trim, and will go on sale next month for around $20,000. The 1.5-liter engine has the same 205 horsepower as the old 2.4-liter four with naturally aspirated gas. However, compared to the normally aspirated engine, torque is up 18 lb-ft to 192. The Civic Si should be enjoyable to drive because it has more power accessible lower in the rpm range and a standard six-speed manual transmission.
A sport-tuned suspension with firmer springs and antiroll bars helps to improve car control. Honda claims the new Si is substantially lighter than the previous version (without providing details). A two-mode adaptive damper system (sport and normal), a limited-slip differential, and larger 12.3-inch front brake rotors are all included as standard equipment.
The coupe and sedan both feature subdued design (at least compared to the Type R). The Si gets wider side vents at the back, black trim on the front fascia, 18-inch, 10-spoke wheels, and center-exit exhaust. No flashy body kits or extraneous wings are present.
It will be interesting to see how the 2017 Civic Si stacks up against rivals like the Ford Focus ST, Subaru Impreza WRX, and Volkswagen Golf GTI. With starting costs in the mid-$20,000 range and greater power than the Si, the competition may damage Honda’s new Si. Alternately, the Si could triumph despite lacking VTEC. As soon as we can get behind the wheel, we’ll let you know.
What vehicles are powered by VTEC?
The 1.8-liter engine in the HR-V, however, uses VTEC to regulate the timing of both intake valves at higher speeds and one intake valve at lower speeds, but not lift.
Although the intake and exhaust valves in Honda’s turbocharged four-cylinder engines have variable valve timing, the lift valves do not. According to Honda, this variation of VTEC controls the intake and exhaust camshafts separately, enabling valve timing to be adjusted for a range of driving circumstances. The Accord, Civic, Civic Si and Type R, and CR-V all employ this technology.
The Odyssey, Passport, Pilot, and Ridgeline’s V-6 engines have variable intake valve lift and timing, and VTEC combines with cylinder deactivation to function in a three-cylinder mode.

Which VTEC engine is the most powerful?
Even if high-rpm flogging is not necessary, it makes for storming fun as the 2.0L turbo 4-cyl. cranks out 306 hp before hitting the redline at 7,000 rpm. This VTEC engine is the most potent street-legal Honda to ever enter America, with a specified output of 153 hp/L.
Driving without VTEC is possible.
Yeah. Unplugged VTEC results in no solenoid engagement, a lower lift cam, a worse breathing engine over 6,00 RPM, less air, more fuel, and an extremely rich engine over 6,00 RPM. Therefore, there was no harm or knock.
VTEC vs i-VTEC: Which is superior?
Honda added i-VTEC, which effectively stands for Intelligent VTEC, for you if variable valve timing wasn’t hard enough before. Since its introduction in Honda vehicles in 2001, almost all of their performance engines have utilised it.
The above-mentioned architecture is used in conventional VTEC engines. Only the lift and duration offered by the two distinct camshaft lobes or profiles can be controlled by this technique. In order to have better control over valve timing, Honda created and combined what is known as i-VTEC, or VTC with VTEC.
Variable timing control (VTC) allows the camshaft to be advanced or retracted in order to manage valve overlap. The exhaust valve never opened and closed simultaneously in conventional VTEC engines because the intake valve always opened first. With VTC, the camshaft lobe angles can be adjusted to allow the valves to overlap or open simultaneously. It can be altered at various RPM levels due to its changeable nature.
