The name of the Honda engine technology is VTEC, which stands for Variable Valve Timing and Lift Electronic Control. VTEC is a type of technology used across many of Honda’s engines, allowing for more power to be produced at higher RPMs and improving overall horsepower. It was groundbreaking technology when it was first introduced and is now widely used in engines today.

Which is better VTEC or non VTEC?
VTEC allows different cam adjustments for lower rpm and higher rpm allowing efficiency at low speeds, but less efficiency and more horsepower at higher rpm. This makes VTEC an ideal engine for both economical driving and performance.
Does Honda still use VTEC?
VTEC is also used on the 2022 Civic Si Sedan, helping produce a broader torque curve, a lower rpm torque peak, and sustained power at higher rpm.
What is i-VTEC engine technology?
i-VTEC stands for Intelligent Variable Valve Timing and Lift Electronic Control, a system created by Honda to improve fuel consumption of Honda vehicles. The VTEC system uses two camshaft profiles and hydraulically selects between the two. This technology was invented by Ikuo Kakitani, a Honda engineer.
Why did Honda get rid of VTEC?
Coincidentally, while CVCC was an emissions control technology, VTEC is being phased out in favor of more conventional double overhead cam (DOHC) technology in pursuit of less pollution.
Is I-VTEC better then VTEC?
Thus, the i-VTEC system provides all the benefits of the traditional VTEC design’s high-end open throttle power, while providing better engine operation at low and partial throttle.
What is the difference between VTEC and VTC?
VTEC still operates the same—using a low-profile cam lobe at low rpm and activating a high-profile cam lobe at high rpm—but its performance is augmented by VTC, which allows infinitely variable control over camshaft phasing.
Which is better i-VTEC or VTEC?
Thus, the i-VTEC system provides all the benefits of the traditional VTEC design’s high-end open throttle power, while providing better engine operation at low and partial throttle.
Why does VTC rattle?
The rattle is caused by insufficient lock in the absence of oil pressure. With a leak, it would take a higher oil pressure to unlock it. This would not cause rattles, but the VTC actuator being locked in low oil pressure situations auch as idle or low rpm with low viscosity oil.
What is the name of the Honda VTEC engine?
DOHC VTEC. VTEC debuted in the B16A engine of the 1989 Honda Integra XSi. VTEC was introduced as a DOHC (dual overhead camshaft) system in Japan in the 1989 Honda Integra XSi, which used the 160 bhp (120 kW) B16A engine.
Are VTEC engines good or bad?
Honda claims that there has never been a warranty claim against their VTEC systems – as in, the solenoids and variable valve/timing system is quite reliable. This isn’t at all to say that these engines don’t fail – of course they do – however they have a very good track record for reliability if maintained correctly.
