New Digital Valvetrain Engine Gives Diesel Efficiency On Petrol Engines
The pursuit of low emissions is serious business. Companies are trying all sorts of engineering tricks to get rid of as much carbon dioxide and nitrogen oxides as they can.
A small engineering firm in the Midlands might have come up with an astounding solution, by ditching the camshaft altogether.
Camcon Auto has developed a fully electronic system it calls Intelligent Valve Actuation (IVA). In essence, an electronic control module sits on top of the engine and directly controls each valve with a rotary actuator.
With full electronic control over each individual valve, IVA can adjust any part of the engine’s airflow to the tiniest degree and at any time.
The net result is a reduction of emissions by up to 20 per cent, while also promising an improvement in power, driveability and performance. With infinite control over the engine timing, the IVA unit can provide exactly what the driver needs at any given time.
The IVA system has been designed so that it can fit onto existing conventional engines, eliminating the need for any expensive additional engine development, and could be on the market in as little as three years.

Wow
Now apply this to a diesel. Boom. Fuel economy.
The world is beginning to turn against diesel. The whole point was to make this as efficient as a diesel
Didn’t koenigsegg make a camless engine a while ago?
Yeah but theirs was controlled by pneumatic or hydraulic pressure (cant remember which) as opposed to electricity like this.
Now when you pop the “valve cover” off, all you see is a circuit board!
I am quite amazed, now that I look back at car history, we have come this far. Imagine if this tech was available in the 80’s, and how much we’d be saving. (Something tells me that might have not been possible…oh well)
great 100 more things to go wrong
i want this on my Subaru…
Why IVA~?
Why not IVAn~?
Just to be clear - I’m still not saying you’re wrong - just that you should hold off declaring one as better than the other until you see them both chooch. One may be skookum, the other crusty. They may both be awesome. They may both be craptastic. They may both be great but then ruined by being manufactured down to a price in a 3rd world sweatshop. You just don’t know. In fact, it may be Betamax vs VHS again - the lesser of the two systems may win because of marketing (i.e. IVA may be inferior but get backing by Toyota or some other heavy hitter and win, or FV may turn out to be inferior and win because of the prestige of Koenigseggegegeg - that’s the world we live in). Or both systems may be wiped out by something neither of us know anything about because it’s unreleased as of yet (or just under the google radar for now). Or that unknown system may only be compatible with one of these systems and the two combine to rule the day. Just look at opposed piston, opposed cylinder engines, for example. Or free piston linear generators (for petro-electric cars).
Too many unknowns to declare that this system or that system is better or more “futurist”. Besides anything else, they’re both parts of an internal combustion engine - something that is 210 years old this year. How “futurist” can either of these technologies be when Tesla and others are making convincing arguments that the ICE should be a thing of the past (using the electric motor, which is “only” 183 years old)…?
Oh, and the weight of the IVA hybrid system really shouldn’t be taken into account since it doesn’t have one, that was just my suggestion of how the system might compete with the pneumatic hybrid system you described the FV system as having. Which I would guess it can be produced without if needs be.
winning on the AVE lingo, keep your d**k in a vice
Please stop putting circuit boards in hot places where the solder comes loose and whole cars become undriveable because of computers.
