What does a Honda VTEC engine do?
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.
Does VTEC increase a car’s speed?
Honda created the Variable Valve Timing & Lift Electronic Control (VTEC) technology to improve the overall performance, efficiency, and fun factor of their vehicles. The technology has become a well-known meme as a result of its frequent use in Fast and Furious movies. Few people are aware of the mechanics behind the expression “VTEC just kicked in, yo!” What you need to know about the system is provided here.
Why does a VTEC valve exist?
Some Honda engines use a mechanical and electronic system called VTEC, which stands for variable valve timing and lift electronic control. This technology effectively gives the engine several camshafts.
The engine’s computer can activate different camshaft lobes at different rpm ranges to modify the timing of the cam. By doing this, the engine can benefit from both the greatest qualities of low-speed and high-speed camshafts.
Some Honda engines have a mechanical and electronic mechanism called VTEC that basically gives the engine several camshafts.
To open and close valves, the camshaft uses rotating lobes that push against the valves.
Which is superior, VTEC or Turbo?
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.
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—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.
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.
So, What’s the Difference Between VTEC and i-VTEC?
By allowing for camshaft angle modifications, i-VTEC adds more valve timing control. The valves must open and close differently for each RPM range in order to operate at their peak performance at both low and high RPMs. The main distinction between VTEC and i-VTEC is that the former does this.
In contrast to the conventional VTEC, i-VTEC offers a smoother power band and improved performance at both high and low RPMs.
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.
Which motors feature 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.

Does every Honda model have a VTEC?
If you have any interest in high-performance vehicles, particularly those made in Japan, you’ve probably heard of Honda’s powerful VTEC engine. The primary source of Honda’s renown is this. Although VTEC has continued on turbocharged Honda engines like the current Type R Civic, it is their four (and six) cylinder normally aspirated engines’ ace in the hole. VTEC has the ability to improve performance, boost economy, and cut emissions. Honda has successfully employed it for all three of these objectives over the years. Are all Hondas VTEC, though? You’ll get the solution to that question in this article.
VTEC has also influenced the development of the “VTEC Just Kicked In Yo” meme genre on the Internet:
But what precisely is VTEC? How is better performance achieved? Does every Honda have VTEC, too? These questions and more will be addressed in this installment of Car Facts.
VTEC is almost universally found in modern Honda models, but it wasn’t always this way. Not a single Honda vehicle had it a little over 30 years ago. Honda gradually integrated it across its whole lineup after first keeping it for performance vehicles. To discover more about what VTEC does, which Hondas have it, and why, let’s take a closer look at how it functions.
What makes Honda VTEC so unique?
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.
Which Hondas are turbocharged?
This engine operates with exceptional economy while providing thrilling acceleration.
The Aspect:
The first turbocharged engine to power vehicles bearing the Honda label on the American market was added to the current-generation Civic series.
- This EarthDreams Technology engine also has direct injection, Variable Timing Control (VTC) on both camshafts, and a dual exhaust system in addition to the intercooled turbo.
- The engine’s ability to deliver all that thrills while maintaining outstanding EPA fuel-economy ratings is maybe its greatest feat.
- 36
- Impressive power output—174 horsepower in the majority of trims—will be appreciated by drivers.
- Instead of using VTEC to evenly distribute torque across the rev range, it makes use of turbocharging’s torque-expanding advantages.
- Additionally, for a continuous burst of acceleration, that torque peak starts low and continues to be strong for a long period as the revs increase.
- Honda’s forced-induction engine exhibits low turbo laga condition that plagues many of its turbocharged competitors—so response to the throttle is swift. This is due to careful tuning and use of a relatively small-diameter turbine wheel.
- This engine’s Si Sedan configuration changes the pistons, valves, and turbocharger settings to boost peak power output to 205 horsepower and 192 lb-ft of torque.
- Also impressive is the torque output, which averages 162 lb-ft across all variants.
