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.

Who employs VTEC?
The phrase “VTEC” has undoubtedly come up before if you’re a car enthusiast, but you might not be familiar with its definition. If you don’t, then read this explanation.
Honda created and uses VTEC, a kind of variable valve-timing system. Variable Valve Timing & Lift Electronic Control is what it stands for. VTEC switches between various cam profiles by varying oil pressure, like the majority of other variable-valve timing systems. The cam profile provides for increased valve lift at higher engine speeds, which lets more air into the cylinder. This contributes to increased horsepower. VTEC has been a feature of many of Honda’s top performance vehicles since its debut in the late 1980s, including the NSX, Integra Type R, S2000, and Civic Type R.
However, VTEC switches cam profiles in a completely different manner. VTEC uses a whole separate set of cams at high RPMs; most variable valve-timing systems alter the timing of the camshaft by increasing oil pressure, opening the valves sooner.
The method can’t be adequately described in words alone. A film was created by Jason Fenske of Engineering Explained utilizing real Honda engines and illustrations to demonstrate how VTEC functions. Watch this video if you’re curious about what goes on inside an engine.

According to Fenske, engines with VTEC have two rocker arms with separate low-profile cams for each cylinder and a central rocker arm with a separate high-profile cam that is inactive at low RPMs. As engine speed increases, oil pressure inside a piston in the rockers locks all three cams together to raise the valve lift. This is the source of the distinctive “VTEC kicking in” sound.
You will now be fully aware of what is occurring within your engine the next time you “go into VTEC” while operating your Honda.

Is Toyota VTEC?
To increase the effectiveness of automobile engines, Honda and Toyota respectively created the VTEC and VVT-i technologies. With Honda’s VTEC (Variable Valve Timing and Lift Electronic Control) valvetrain system, engines may attain turbo level-specific output without suffering from the poor fuel efficiency that turbocharging typically brings. The VVT-i (Variable Valve Timing with Intelligence) system, which Toyota created, has a number of variations, one of which, the VVTL-i (Variable Valve Timing and Lift Intelligent System), is comparable to the VTEC system. VVTL-i, which was initially utilized in the 1999 Toyota Celica SS-II, has been phased out because it does not comply with Euro IV pollution standards.
Has Nissan adopted VTEC?
Nissan invented the variable valve timing technology used in automobiles with the Nissan Variable Timing Control[1] or Nissan Valve Timing Control System (often abbreviated as N-VTC, VTC, NVCS, or NVTCS). 1987 saw the debut of N-VTC on the VG30DE and VG20DET engines.
By turning the affected camshaft in relation to the sprocket, N-VTC modifies valve timing while leaving valve lift and duration alone. This rotation is made possible by an electric solenoid that the vehicle’s ECU uses to control the flow of pressurized engine oil into and through the slave mechanism and the cam, axially moving the timing of the camshaft relative to the sprocket. Depending on whether the engine speed is high or low, the valve to crank angle timing adjusts at set intervals. Similar to Honda’s VTEC system in that it is hydraulically actuated, NVTCS modifies a separate component of the valve train, making it more akin to the I in I-VTEC. [2] [3] Nissan engines with NVTCS are simpler, quieter, and don’t need any additional maintenance because NVTCS Nissan engines have lower engine speeds than Nissan engines with VTEC. [Reference needed] N-VTC is present on both the intake and exhaust cams in several Nissan engines, such as the GA16DE, QG16/18, SR20DE/DET (S14–15), or RB25DE/DET (R33–R34 GTS/GTS-T, GT/GTT. On more recent engines like the VQ and VK series, NVTCS was eventually phased out and replaced by a continuously variable system known as CVTCS. [4]
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.
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.
How many HP can VTEC produce?
The i-VTEC system is implemented in two different ways in the K-Series engines. The first category is for high-performance engines, such as the K20A2 or K20Z3 found in the 2002–2006 RSX Type S or the 2006–2011 Civic Si, and the second category is for economy engines, such as the K20A3 or K24A4 found in the 2002–2005 Civic Si or the 2003–2007 Accord. The DOHC VTEC system of the B16A’s and the performance i-VTEC system are essentially equivalent. Per cylinder, each intake and exhaust cam has three cam lobes. However, the valvetrain also benefits from continuously changing intake cam timing and roller rockers. Performance i-VTEC combines VTC with traditional DOHC VTEC (which operates for intake valves only). Both the performance and economy i-VTEC engines offer the VTC.
The K20A3/K24A4 engines’ economical i-VTEC is more like the SOHC VTEC-E because it only has two intake cam lobes—one very small and one larger—and no VTEC on the exhaust cam. Only one intake valve fully opens at low RPM, encouraging combustion chamber swirl and better fuel atomization. This makes it possible to use a leaner air/fuel mixture, increasing fuel efficiency. Both intake valves are driven by the larger intake cam lobe at higher RPMs, increasing overall air flow and top-end power.
The factory rated power output of the two types of engines makes it simple to tell them apart: performance engines typically produce 200 hp (150 kW) or more in stock form, while economy engines rarely produce more than 160 hp (120 kW).
What VTEC engine has the fastest speed?
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.
What VTEC engine is the best?
The B18C6 is one of the best-rated Honda VTEC engines. This 1.8L 4-cylinder engine was installed in Honda Integra and Acura Integra Type R models sold worldwide from 1999 to 2001. For a car that was so light, its 195 horsepower and 130 pound-feet of torque were excellent. Additionally, it had a redline of 8400 RPM, while VTEC began to operate at 5700 RPM.
Because it was simple to alter and had that distinctive DOHC VTEC sound when you approached the VTEC engagement point, the B18C platform rose to great popularity. This results in a lot of power in the higher RPM ranges, making the cars they are in feel sportier and more enjoyable.
The B18C is still recognized as one of the best VTEC motors ever made, and it continues to be in high demand all over the world. If you’re looking for an excellent, low-mileage B18C, be prepared to pay more.
VTEC vs 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 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.
What sets VTEC apart?
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.
