HONDA V-Tec Operation
HONDA V-Tec Operation Get the book here: https://www.createspace.com/4321251 Describes the operation of the HONDA V-Tec variable valve timing system. Like never seen before, this animation goes into details on the mechanical principle of the V-Tec system. The Honda V-Tec system is a dual setting variable valve timing system. It is meant to give high efficiency and low power at lower RPM and high power and low efficiency at higher RPMs. There have been a few incarnations of V-Tec, which came out in the late 80's, but their principle is the same. See it all here with high quality visual details. *************************************************************************** ********* Amazon Printed-Books & Kindle: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dstripbooks&fiel d-keywords=mandy+concepcion Google Play Android APPs: https://play.google.com/store/search?q=mandy+concepcion&c=apps Amazon Video DVDs: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dmovies-tv&field -keywords=mandy+concepcion Barnes & Noble Nook: http://www.barnesandnoble.com/s/mandy-concepcion?keyword=mandy+concepcion&s tore=allproducts Apple iTunes iPad: http://itunes.apple.com/us/artist/mandy-concepcion/id449573393?mt=11





How VTEC Sound Like
This is what VTEC should sound like. The crossover to the high cams should be linear without any power loss. My car was tuned to make maximum power across the RPM range. This was done in 4th gear. I Dynoed 210whp & 154wtq on a Dynojet. Car: 2008 Honda Civic Si FG2 Tune: Hondata FlashPro Mods: I/H/E VTEC kicks in at 4k RPM all the way to a redline of 8.6k RPM. "VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts. As the engine moves into different rpm ranges, the engine's computer can activate alternate lobes on the camshaft and change the cam's timing. In this way, the engine gets the best features of low-speed and high-speed camshafts in the same engine." - HowStuffWorks Here is my Civic's record at the drag strip: https://www.youtube.com/watch?v=yI3eB-ZJeWo

How VTEC works
The DOHC i-VTEC system (one of the two cams shown). Found in the Honda/Acura K series, F20C and F22C1 engines, the i-VTEC system uses roller rockers, continuously variable intake cam timing (VTC, not shown) and three separate cam profiles for both the intake and Exhaust valves of each cylinder. These features improve power and efficiency of the engine across its entire rpm range. Below 5,800 rpm the offset and low lift of the valves aids in fuel atomization. This provides improved low end torque and fuel efficiency by creating a powerful swirl in the cylinder and by keeping the intake air charge at high velocity. Above 5,800 rpm a high lift, long duration cam profile is engaged by the synchronizing pistons to provide greatly improved high rpm power and torque.

What is VTEC and How Does it Work? - EricTheCarGuy
VTEC or Valve Timing Electronic Control is a system that's been used by Honda in passenger cars since 1991. I believe the 1991 NSX was the first production vehicle to get this system. It has since been used in several other Honda vehicles. Late model VTEC equipped vehicles use the iVTEC system which also changes cam timing as well as lift and duration. The system is designed to give you the 'best of both worlds'. You get to switch between 2 cam profiles. One for fuel economy, one for performance. A lot of people think that when VTEC kicks in you get an extra Boost of power. Not true in my experience. It does however extend the torque curve to give you more performance after it does switch over. There is no set RPM where VTEC switches. The computer looks at several variables and calculates when to activate the VTEC solenoid. It's a cool system and for the most part rarely has issues. The most common issues I've seen with VTEC are the result of low, or incorrect oil viscosity. So if you have a VTEC engine, keep the oil topped off and make sure you use the viscosity listed on the oil cap. The animations are courtesy Honda Motor Company, thanks guys.
