New Advanced VTEC System and Diesel Engine - Bangin & Blowin

Feb 21, 2007

VTEC 3.0
Honda expects its new Advanced VTEC system to hit production vehicles in 2009
First it was VTEC. Then it was i-VTEC. Now there's Advanced VTEC, Honda's latest engine development. Promising to improve performance while increasing fuel economy and reducing emissions, A-VTEC is an evolution of the original VTEC concept-making the engine as efficient as possible.

An engine equipped with A-VTEC accomplishes this with a combination of VTEC and the continuously variable phase control of VTC (Variable Timing Control). Intake valve lift and phase is optimized in response to every driving condition. Torque is increased significantly 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.

Honda estimates an engine with A-VTEC results in a 13-percent improvement in fuel economy. Exhaust emissions meet LEV2-ULEV regulations or 75 percent lower than those required by the 2005 standards. A production vehicle equipped with A-VTEC is expected in 2009, twenty years after Honda first introduced VTEC.

Don't Forget The Diesel
Next-generation diesel engine features a reduction in nitrogen emissions
Honda also announced its next-generation diesel engine. The diesel is the world's first system to use the reductive reaction of ammonia generated within the catalytic converter to "detoxify" the nitrogen oxide by transforming it into harmless nitrogen gas. Based on Honda's calculations, it will meet strict EPA Tier II Bin5 emissions requirements, which are among the toughest in the world.



According to Ferrari, the collector wanted the look of his new car to be inspired by the Ferrari 330 P3/P4 and the 1966 Dino 206 S.
