Honda reveals the Advanced VTEC engine

advancedvtec3.jpg


Honda's engineers have been busily figuring out how to make their VTEC engine better, and today the auto giant released the first details about the next-generation powerplant, which they're calling Advanced VTEC. Honda says it plans to have the new engine in a production car within the next three years.

Torquier at all speeds, the engine also sets the valves for low lift and early closure at lower load levels, which boosts fuel economy to the tune of 13% over the current 2.4L i-VTEC when the engine is equipped with the proper intake bits. In addition to being punchier and more economical, the engine is cleaner-burning as well, garnering a LEV2-ULEV emissions rating.

This is good news. While research and implementation of the various alternative fuel and propulsion solutions is most welcome, there's a lot to be said for the regular, economical four-cylinder gasoline engine. If Honda is on the verge of producing a four with power, more torque (hooray!), better fuel economy and cleaner emissions, the Advanced VTEC is going to be a highly attractive alternative to the alternatives.

PRESS RELEASE:
Honda Develops Advanced VTEC Engine Combining High Power and Environmental Performance

September 25, 2006–Honda Motor Co., Ltd. has further advanced its VTEC (Variable Valve Timing and Lift Electronic Control System) technology with the development of the Advanced VTEC engine, which achieves high performance along with outstanding fuel economy and lower emissions. The new engine combines continuously variable valve lift and timing control with the continuously variable phase control of VTC (Variable Timing Control). Honda plans to release a production vehicle equipped with the new engine within three years.

This new system permits optimum control over intake valve lift and phase in response to driving conditions, achieving improved charging efficiency for a significant increase in torque at all engine speeds. Under low to medium load levels, the valves are set for low lift and early closure to reduce pumping losses and improve fuel economy.

In combination with optimized intake components, these advances in control technology result in world-class dynamic performance along with approximately 13%* improvement in fuel economy. The new engine is also exceptionally clean, with exhaust emissions that meet both U.S. Environmental Protection Agency LEV2-ULEV regulations and Japanese Ministry of Land, Infrastructure and Transport requirements for Low-Emission Vehicles, with emission levels 75% lower than those required by the 2005 standards (based on Honda calculations).
* Engine only, as compared to production 2.4-liter i-VTEC engine (Honda calculations)

I find it amazing how Honda is able to improve on something that is already top-notch as far as I'm concerned. Although, I feel my ol' vtec is going to be disappointed when it hears that there is not only an "intelligent" vtec, but an "advanced" vtec as well. Oh well... I've still got 166,000 miles and it runs like new :thumbsup:

interesting...A-VTEC huh? but they sure r replacing the I-VTEC pretty quickly.... i'm also guessing honda will venture more into diesel engines soon

wish they would say how much more torque it was putting out. "more torque" is vague and could be basically nothing.

You're right.
Compared to the increasing weight of each generation, the added torque to a heavier car can equal out to a car still being torqueless

kinda sorta. from what i understand, i-vtec was just variability on the intake cam (advance or retard up to 13 degrees i think :confused: in either direction). it seems like, from what im inferring, theyre going to put it on the exhaust side as well with a-vtec. theyll probably make them variable and independant of each other. so the intake could be at -7 while the exhaust is at +3. man, theres going to be some complex code in that ecu. hondata's going to have one fun time trying to figure it out :stupid:

They've already developed a top-of-the line diesel, supposedly better than any american diesel. Was that article posted around here? I may have to search...

it's nice to see that the new A-VTEC is being tested out in an Accord Euro-R

score one for the Accord

although this is great for their base consumer population, this new engine with all its ecu controlled varialbe cam timing, will make it extremely difficult for the small population of tuners to tune the ecu. hondata still has yet to come out with a k-pro for the new si's k20z1 due to the drive by wire throttle. new technology...its a double edged sword :(

yeah....last i heard, they were planning on opening a plant just for diesel vehicles, or have they already? i knew they have some diesel engines in R&D, but have they fully developed one yet? diesel is basically gonna be big in the next 2 years with all the stuff happening in the industry...
