Honda V-tech & i-vtech engines?
 

What is so special about v-tech & i-vtech engines on hondas? How are they different from the regular engines?

Adjustable timing / lift / cam profiles. Basically once the engine is spinning past a certain number of revolutions / minute, it shifts into a mode that allows it to make better use of its fuel and air at that higher speed.































Regular VTEC will either be engaged or not engaged, while i-VTEC is a variable system - it can be working 'a little' or 'a lot' depending on how fast the engine is running. Honda has VTEC systems in use to increase performance as well as improve fuel economy. Other manufacturers use similar systems to achieve similar results.

VTEC (Variable Valve Timing and Lift Electronic Control) is a valvetrain system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine. This system uses two camshaft profiles and electronically selects between the profiles.VTEC serves as another method to derive very high specific output from lower displacement motors. In other words you dont need a turbo or supercharger to get some real balls out of a naturally aspirated small motor.

VTEC (Variable Valve Timing and Lift Electronic Control) is a valvetrain system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine. This system uses two camshaft profiles and electronically selects between the profiles. This was the first system of its kind. it helps both fuel economy and perfomance and is truly a wonderful technology honda has brought us.































i-vtec is the same thing, however it utilizes the camshaft to advance and move on its own while being driven. think of it this way, vtec is like the tv. the old school tv where it was just black and white. then every other car manufacturer tried jumping on the bandwagon for it cuz it was so good but it took almost 5-7 years for each car manufacturer to come out with it. then when they finally scraped their own vvt technology, I-VTEC came out. now i-vtec is just like the color tv, so now all the car manufacturers are back at the starting line saying "omg wtf? we gotta do this crap again? dang it"































honda motors are just so efficient and so great, they compete/match up against higher cylinder cars when honda engines are just usually 4 cylinders. if you're considering buying a new car you should definitely look into getting a vtec engine since it makes the engine much more powerful and is great for fuel economy. good luck
