Can you make VTEC stay on all the time?
You could, but you will decrease your performance. Honda spent alot of R&D time to come up with the most efficient point for the crossover.
Can you turn off VTEC?
You can turn VTEC on and off at will with the flip of a switch.
When does the VTEC go on in a Honda?
It’s active when the engine is operating relatively high in the rev range, and you rarely get there in normal driving conditions, especially if your car has an automatic transmission. But, if you’re the shift-your-own-gears type and you like twisty roads, VTEC makes a noticeable difference.
Which is better a VTEC engine or a regular engine?
However, there are legitimate reasons for it. Hondas with VTEC engines are much more efficient across a wider RPM range than most other vehicles, and arguably are much more fun to drive for those of us who value pick up and go. But for a large majority of us, you’ll likely not “ride VTEC” in everyday driving.
How does the VTEC system in a car work?
For a combustion engine to work, it requires four things: Air, fuel, compression, and spark. For the purposes of understanding the VTEC system, we’ll focus here mainly on the air part of that equation. A part of the engine known as the camshaft controls how much the valves open and then close, and therefore how much air goes into the engine.
Why does Honda VTEC have lower valve lift?
Valve lift also plays a key role: the higher a valve lift opens, the more air-fuel mixture enters the cylinder and the more it combusts, which yields more power. However, standard engines tend to have lower valve-lift numbers. This dilemma was solved with the arrival of the Variable Valve Timing, or VVT, system.
How does Honda’s variable valve timing system work?
VVT basically allows cam timing to change, delivering greater efficiency and power over a wider range of engine RPMs. Previous variable valve timing systems existed, but Honda’s VTEC system stood out from the pack. It works by employing several cams of different sizes in the camshaft, as well as several rocker arms placed next to each other.
What’s the difference between Honda VTEC and i-DSI?
For instance, at mid-range RPM speeds, the interval between the first spark plug ignition and the second is more pronounced, while at high RPM speeds, the system supplies an almost simultaneous ignition on both ends. Both systems employ ingenious ways to basically squeeze the performance out of relatively small engines all across the RPM range.
