Why did Honda come up with the VTEC system?
Honda developed this variable valvetrain system in order to offer efficiency and power in smaller engines. VTEC systems use two camshaft profiles, one for bottom end economy and another for top end performance.
When did the Honda Integra VTEC come out?
In April 1989, Honda’s new Integra was launched with a new DOHC/VTEC engine. It was not only very powerful, but it also idled more smoothly and had no staring problems. The word praised it for having the first valve mechanism that changed the timing and lift on the intake and exhaust sides simultaneously.
What does the VTEC system do at low rpm?
At low rpm, the VTEC intake valve timing and lift are optimized for rapid swirl-pattern cylinder filling. As engine rpm builds past 5000 rpm, the VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.
What’s the difference between VCM and VTEC engines?
VTEC has evolved over the years into hybrid technology, VCM (Variable Cylinder Management) which is a form of cylinder deactivation and the computer-controlled i-VTEC. But the basic idea championed by mister Tochigi lives on. click to load Disqus comments for this story This enables Disqus, Inc. to process some of your data.
When did Honda come out with the VTEC engine?
Eventually the mechanism evolved into Honda’s VTEC (Variable Valve Timing & Lift Electronic Control System) engine. Launched via the 1989 Integra, this innovative technology surprised the world with a new level of performance from a compact, fuel-efficient engine. “Find a new technology to lead the next generation of Honda engines.”
What does VTEC do on a Honda Accord?
The Accord system combines Variable Timing Control (VTC), which continuously adjusts the intake camshaft phase, with Variable Valve Timing and Lift Electronic Control (VTEC), which changes valve lift, timing and duration of the intake valves. At low rpm, the VTEC intake valve timing and lift are optimized for rapid swirl-pattern cylinder filling.

Which is 2.0 liter VTEC engine is really best?
Up next is the B20-powered EK9 Civic Type R, which, visually, looks the most hardcore of the bunch. The video notes that the engine uses a B20B block with a B16B head. However, instead of doing a time attack hot lap, the group, instead, jumps right into a three car track battle, since the EP3 is out for the day.
