VTEC (which stands for Variable Valve Timing and Lift Electrical Control) is a mechanical and electronic technology used in select Honda engines that allows the engine to operate as if it had several camshafts, allowing the engine to produce more horsepower.In order for the engine to operate at different rpm levels, the computer in the engine may activate alternate lobes on the camshaft and adjust the timing of the camshaft.
With the VTEC technology, you may get high-RPM performance while maintaining fuel efficiency and stability at low-RPM speeds. Furthermore, the shift is seamless, enabling for consistent performance throughout the whole powerband to be achieved. The engine computer is in charge of controlling the operation of switching between the two cam lobes.

How does a VTEC engine work?
According to Fenske, VTEC-equipped engines feature two rocker arms, each with its own low-profile cam, for each cylinder, and a central rocker arm, each with its own high-profile cam, which is not utilized at low RPMs but is employed at higher RPMs.As engine speeds increase, an oil-filled piston inside the rockers is compressed, causing all three cams to lock together, increasing the amount of valve lift.
What is Honda VTEC?
VTEC is an abbreviation that stands for Honda’s Variable Valve Timing and Lift Electronic Control technology, which was previously described. This is the variable valve timing system used by Honda. Variable valve timing allows engineers to take full use of the engine’s high and low rpm ranges by adjusting the timing of the valves.
How does a VTEC solenoid work on a diesel engine?
When the engine is running at a high RPM, the VTEC solenoid is triggered electronically, and the camshaft is switched to a bigger lobe profile by the use of a pin that is actuated by oil pressure. As a result, the valves open more widely, enabling more air to enter. Additionally, the fuel injection system supplies extra gasoline, which increases the engine’s performance.
What is Honda’s i-VTEC?
Honda’s i-VTEC technology is the most sophisticated version of the VTEC system. The i-VTEC term simply means for intelligent VTEC, and it is a system that combines their basic VTEC system with their sophisticated variable timing control (VTC) technology to produce superior performance. A modification of the timing gear that powers the camshaft is possible with VTC.
Are Honda VTEC engines good?
However, the durability of a VTEC engine is directly proportionate to the conditions in which it will be operated, and in general, VTEC engines are extremely dependable engines. They have a long service life, although they do begin to use a significant amount of oil with time.
How does VTEC activate?
A 12V signal is transmitted to the engine’s VTEC solenoid, which initiates the procedure when the engine speed reaches a certain level established by the ECU.
What is VTEC in Honda engine?
Honda VTEC is a sort of variable valve-timing technology that was created and is now in use. This acronym is an abbreviation for Variable Valve Timing & Lift Electronic Control. Variable oil pressure is used to move between different cam profiles in VTEC, just as it is in most other variable valve timing systems.
Is VTEC better than Turbo?
Turbo engines produce more torque and horsepower, whereas VTEC engines are more concerned with extracting the maximum amount of horsepower from the engine. Torque on VTEC cars can only be felt in the VTEC range, which is anywhere after 5,500RPMs, but the torque is still insignificant when compared to the torque output of a turbo engine.
At what speed does VTEC kick in?
At around 2300 rpm, VTEC begins to operate to convert the engine from a three-valve to a four-valve configuration.
How do I know if VTEC is working?
Until vtec is reached, the meter should indicate very, very low voltage on the display. If the vtec system is on, the voltage should be approximately 12 volts. If this is not the case, it is possible that your ecu is not operating properly.
How much HP does VTEC add?
The following is certain: installing VTEC in an engine will boost the total power output and make your automobile quicker. VTEC should result in a power increase of around 10-30 horsepower.
Does VTEC make a sound?
Is There a Sound With Vtec? Is There a Sound When VITEC Makes T? Yes, it is correct. You may notice the noises of an increase in the cam lobe as the engine begins to press an additional lever to adjust the tone of the engine.
What old Hondas have VTEC?
What Hondas from the past had VTEC? In the case of Honda Civics, VTEC is used to refer to models such as the EX, EX-L, HX (6th generation), Si, Si-R, VTi VTi, and Civic Type R. (CTR).
Do all Honda engines have VTEC?
Is it true that every Honda engine has VTEC? In the past, Honda has employed VTEC engines; however, they have not always used VTEC standard; in addition to developing an i-VTEC engine, Honda is also improving on their original VTEC system in order to give a smoother migration into power.
Is VTEC fast?
When it comes to VTEC engines, the Honda Civic Type R of the 10th generation FK8 is right up there with the best of them in terms of power. Its 3,900-pound displacement allows it to reach top speeds of up to 88 miles per hour and produce a maximum output of 306 horsepower. Engine configurations with a size of 0L and four cylinders.
What engines have VTEC?
The EX, EX-L, HX (6th generation), Si, Si-R, VTi VTiR, and Civic Type R (CTR) are all VTEC-powered automobiles, as is the Civic Type R (CTR).
Is VTEC only for Honda?
To sum it up, yes, VTEC is exclusive to Honda and yes, there are alternative technologies that accomplish the same, or very similar, objectives.
