iVTEC How it Works -EricTheCarGuy

Автокөліктер мен көлік құралдары

iVTEC How it Works is a long standing requested video. Back with I did the video on the VTEC explanation I was asked about doing a video on iVTEC which is slightly different than VTEC. First you need to understand the basic operation of the cam shaft, once you have that, and you know a little about how that cam shaft effects performance, you can then begin to understand how iVTEC works. In essence, as far as the Honda system is concerned, it varies the cam 'timing' to optimize performance and fuel economy. Many companies employ similar systems to this but they may perform the operation differently. This video focuses on the Honda iVTEC system.
That said, you may notice that the VTEC system on this K series is a little different in that instead of having a cam with a higher lift and duration, it switches between 1 and 2 valves on the intake side. So when VTEC engages on this engine it actually activates another valve in the cylinder instead of changing lift and duration. It still alters cam timing via the iVTEC system however. Once again, to optimize power output and fuel economy.
Either way, I hope this video helps with your understanding of camshafts, cam timing, lift, duration, VTEC, and iVTEC systems.
Thanks for watching.

    Hell yeah i just got myself a 06 honda accord LX 4 cylinder just now gettin broke in lol at 100k got it with 99,000 before i had a 08 toyota corolla until i totaled it n i gotta say i like my honda accord way better than i did with my toyota corolla its hard 2 say which 1 is better 2 me toyota and honda are about the same in terms of reliability but i always heard hondas automatic transmissions are a little on the weak side thats why im making sure mine i change the tranny fluid and filter and when i do that gonna put lucas transmission stop slip in there thats the only down side with honda is there automatic transmissions are on the weak side so if you wanna stomp on the gas and b race car driver your best bet is to get a manual trans. But as long as your doing normal everyday driving and dnt beat the shit outta your honda race it then the auto tran. Should last i would think

    A good followup video called "The Future of the Internal Combustion Engine - /Inside Koenigsegg" shows an engine that instead of using a camshaft, each valve is individually controlled by a electromagnet. Basically makes it so each cylinder can have its intake and exhaust individually tuned.

    Eric want to thank you for all your great educational videos. I have a Question I've surfed the web looking for an answer maybe I'm just not wording things right. But i hope you may have some insight. So i bought my sons 1st car he wanted something to work on, we found a 1993 Honda civic DX Automatic with a D16Z6 VTEC in it. I noticed the Solenoid & pressure switch where not connected with wires actually cut. The VTEC is not working cause its not connected, I've looked and there is plenty of instructions on how to connect VTEC for a manual transmission using wires to the ECU seems simple enough. But i haven't found a video or any 1 talking about how to do a automatic for VTEC 1 video said opening up the ECU & having to unsolder & re-solder something in the ECU? Now can this be done or am i just stuck? Thank you once again. J & Aron in TN.

    at 4:05, where the head is installed on the car-- why does the intake cam only appear to have a lobe with actual lift on the center? the lobe next to it seems to be just flat round. does this engine use the vtec solenoid to actuate a different cam profile or just to keep one intake valve from opening, increasing fuel economy?

  • @sam111880
    @sam1118809 жыл бұрын

    hummm curious i haven't study closely the exhaust cam lobes to the intake lobes is there a 90 degree out of phase or something curious if they are all out of phase by a certain amount or if they all are a little different in phases.... i know they can have different durations (or sharper/longer lobes but not sure if there phase degrees between the exhaust and intake are always around the same for non vtec as well as vtec) ... it would stand to reason that one could make VTEC/iVETC all off of a motor or electrical means without any pully wheel or sprocket for the cam to get more optimal computerized timing some day
