www.howstuffworks.com is your friend

 

Check hondacars.com for VTEC info.

 

thanks appreciate it. but can someone explain it to me in simplier form.

 

it doesnt get any simplier than from the above link

 

1. VTEC uses two seperate cam lobes to alter performance below and above a certain set rpm. It is considered a good engine, because it uses this technology to help get the best of both worlds as far as low end and high end performance.
2. I-VTEC is the next generation of VTEC. I am not really sure on I Vtec so I dont wanna blow smoke up your ass about it.
3. The big difference is that a DOHC motor has two cams where as a SOHC engine uses one cam. With a DOHC there is one cam for the intake valves, and one for the exhaust. The SOHC uses one cam to lift both the intake and exhuast valves.

 

thanks. but what are cams?

 

seriously... www.howstuffworks.com search for anything related to cars you want to know about.

 

heed the advice of the noopy :snoopy:
