VVT-i and VANOS are cam timing systems that work just like Honda's new VTC system. VVTL-i uses a lift system like VTEC with a secondary (larger) cam lobe inbetween the smaller primaries, as well as VVT to vary the intake cam timing. So really, systems like VVTL-i and I-VTEC are pretty much identical in how/what they do. In the states though, nobody but Honda used a lift-only system exept Honda's with VTEC.

 

dave, we need these types of intellectually stimulating threads on HondaList! hmmm.......

Na zdravi!

 

LOL, tell me about it!

 

Once again... NA ZDRAVI!!!!

 

Since I've gotten two emails about "Na zdravi!" I'd figure I'd explain... it translates to "cheers" or more literally, "to good health" in the Slavic languages... so it's the perfect saying for a toast... to good health! Na Zdravi!

 

za zdorov'e !

 

vyborny!

 

ay no bueno!

 

na zdrowie! < one of the slavic languages.
Anyway, last year there were rumors that Renault has developed an engine that uses electro-magnetic energy to operate the valvetrain in their new 110deg. V10's. The valve timing was infinitely variable, the valve action was almost instant and the elimination of the mechanical parts fried up a lot of power. The bad side of it was supplying the power to the solenoids, 10 combustion chambers, 4 valves per cylinder singing at 19,00rpm drained a lot of power. That engine was said to be able to spin to 21,000rpm. The final product was a powerful engine but the 110deg. made the block too flat and the fatigue life of the motor was short because of the major vibrations and torsional loads. The motor needed a lot of electrical power to run the solenoids and that meant a lot of weight, the solenoids also added a lot of weight. That engine program was dropped and the chief engine designer fired when he couldn't(maybe wouldn't) come up with a new engine for Renault that was at least some what competitive. BMW had the strongest engine in F1 last season but the valve-train was still operated with quad camshaft's and a pneumatic system, which was developed and used by ---Renault---.

 

interesting stuff

 

wait a minute, back to the engine codes, i was always under the impression that the base model rsx has the k20a3 engine. the type S is the k20a2, and the JDM type R has the k20A.

 

Honda chose the path, others just followed!

VTEC could only be patented for 5years in most countries, then the patent runs out and others are free to almost 'copy'.

 

that is correct...
there is no such engine called the K20C

yeah really, wtf are you guys thinking

i thoughti was the only one since no one said anything about it.
