When did the DOHC VTEC engine come out?
The DOHC VTEC improved the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. Since its first introduction in 1989, the VTEC technology has completely changed the way the world looked at engines.
What does the VTEC system in a Honda engine do?
Image Gallery: Engines The VTEC system in Honda engines allows the engine to have multiple camshafts. See more car engine pictures . If you have read How Car Engines Work, you know about the valves that let air into the engine and let exhaust out of the engine. You also know about the camshaft that controls the valves.
What’s the difference between a VTEC and i-VTEC engine?
Both VTEC and i-VTEC engines are essentially the same. Where the i-VTEC technology differs is with the inclusion of the VTC, which further improves the fuel economy and performance of the engine.
Which is the earliest implementation of VTEC-E?
The earliest VTEC-E implementation is a variation of SOHC VTEC which is used to increase combustion efficiency at low RPM while maintaining the mid range performance of non-vtec engines.
What does setting VTEC at 3, 000 rpm do?
Since the vtec cam lobe is much taller, it can now provide more air and duration the motor needs to keep making power @ higher RPM. Now think about it. What does setting VTEC at 3,000 rpm do? It makes a cam lobe designed to work well at HIGH rpm to work at LOW rpm.
What can a field of Japan VTEC controller do?
Join Discussion…… Field of Japan has put together a nice little VTEC controller which does everything a VTEC controller should do, plus it adds the powerful capability of allowing the tuner to adjust fuel delivery up to ±30%, in 1% increments. The fuel numbers can be set at eight points on the rpm band (1000, 2000, up to 8000rpms).
How does the Honda VTEC engine timing system work?
A third option is to change the cam timing profile, of which Honda VTEC was the first successful commercial design for altering the profile in real-time. The VTEC system provides the engine with valve timing optimized for both low and high RPM operations.
