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 makes the Honda VTEC engine 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.
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.
The Honda i-VTEC engine is it 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.
Which engine works best with the Honda Civic?
But the decision for the top slot on the list was comparatively simple. Even while the high RPM power and output per liter of the B and K-series four-cylinder engines are remarkable, there is one Honda engine that is marginally superior.
That would be the F20C, which was created for the Honda S2000 roadster with rear-drive. The 2.0L F20C, which was packed with racing DNA and produced an astounding 240 horsepower, ranks among the highest specific output production engines of all time. The S2000 became an instant classic as a result.
Of course, the bigger F22C, which debuted in the AP2 model a few years later and had enhanced low-end torque at a somewhat lower redline, is in some ways the superior engine overall.
However, the original F20C is our choice for the best of the best when it comes to sheer engineering brilliance.
Which Honda’s engine is the 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.
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 Honda engine is the quickest?
Car Crate for a Civic Type R The 2.0-liter DOHC direct-injected i-VTEC Turbo engine in the Civic Type R generates a maximum 295 lb-ft of torque from 2,500 to 4,500 rpm and 306 horsepower at 6,500 rpm, making it the most potent Honda automotive production engine ever produced in America.
How many horsepower is there in VTEC?
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).
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.
When did Civics get VTEC?
A revised Civic with larger proportions and a lower hood line was unveiled in September 1987. For different markets throughout the world, a broad selection of models and trim levels were available. The Japanese market SiR was the most notable (featuring the B16A 1.6-liter DOHCVTEC 4-cylinder engine). Although carbureted variants were still available elsewhere, all American cars had electronic fuel injection. For the whole model range of the fourth generation, a completely independent rear suspension was included. [19] The Honda CRX also continued to be a member of the Civic family, which included the base model, HF, and Si models in the United States. A four-door variant known as the Ballade was produced by Mercedes-Benz South Africa in accordance with a contract; the models were 1500 16V, 1600i 16V, and 1600i 16V DOHC. SE model vehicles were the first 800 vehicles built at the then-new Honda facility in Alliston, Ontario, Canada. These Special Edition versions had color-coordinated twin mirrors and all-white side molding that complemented the white body. A blue stripe wrapped completely around the body molding. Each vehicle featured upgraded interiors and an exhaust with a chrome tip.
Does VTEC exist in all Civics?
Three separate Honda Civic models all have one of the two available VTEC-equipped engines that are available for new Honda Civics. The two engines in question are both four-cylinder, lightweight K20 engines, which are well respected for their performance. The small four-cylinder engines developed by the K20 series are possibly the best ever made, including astounding power-to-weight ratios, cleverly simple designs, and incredibly high reliability.
The naturally aspirated K20C2 in the base trims of the Civic sedan and the turbocharged K20C1 in the Civic Type R are the two K20 engines that make use of VTEC in the 2021 Civic. The K20C2 maximizes engine efficiency by using an updated i-VTEC technology for both the intake and exhaust valves. The K20C1 uses VTEC only on the engine’s exhaust side, while a turbocharger forces air into the engine’s intake side at a high pressure. This configuration places a high priority on power and increases the engine’s horsepower and torque without requiring more displacement.
