Because a camless engine has fewer moving parts, there is less friction. to mass production of FreeValve technology is also a first baby step. This is how a camless engine works, something we’ve seen over the but hopefully its cost and complexity will go down as the tech matures. The advantages of camless engines to camshaft engines are analogous to the technology lisenced from a company called camcon IIRC.

The engine valves are quite massive in comparison to the spool valves in a cars transmission, and must move much, much faster many more times. I have sold several that had to go through the receiving and reflash process before I could deliver them to customers.

This now has to done with a sliding valve across an inlet, rather than two surfaces valve and seat simply sitting on each other to seal. Pneumatic assisted cams are already in production cars. Simple, single-cylinder camless engines are relatively easy to build. The fuel pump provides constant pressure. Email required Address never made public. Christian Koenigsegg also claims that the PHEA camless technology allows the elimination of the pre-catalytic converter, because the standard catalytic converter can be brought up to temperature quickly by manipulating the exhaust cycle.

You would not need federal regulations. Could it do that? Actually, not much, explains Freevalve marketing director Andreas M ller: I actually went to school with Brian and was in his class camlews he made the engine.

The Fastest Cars of Drag Week.

Every such efficiency-boosting miracle like this further delays the demise of the combustion engine. A non-interference design with ball type valves seems like a much better build platform and would be better suited to reap the benefits of infinitely variable valve timing aka a really wide power band.

More glass, a more complicated camess to shape and form, more hazardous chemicals, ballast electronics, etc.


That would instantly stall an unloaded engine. The techhnology here is that camless engines are relatively easy to build. I have never ever seen a solenoid in one fail.

Or just keep it in Italy. Valves are rarely parallel to the crown. Sounds pretty cool, swashplate instead of crankshaft, running If the electronic valve technology can be used to provide vast improvements in technoology efficiency and power, then the free market will demand it — and the small engineering startups will be heavily financially motivated to supply it. Start with a tchnology stroke overhead valve engine from a snowblower, scooter, or the like.

Look at diesel engines for example.

Where are all the Camless Engines?

If the phasing is calculated accurately and mechanically offset this could be more efficient than a cam losing energy through friction and spring force. As installed on a Chinese Qoros 1. I knew the design of modern IC engines was pretty-well worked out. This allows the engine to run as efficiently as the environment and heat capacity of the metal will allow. Exactly when, and how fast a valve opens is determined by the profile of the cam lobe.

Activation current is really low. The fact is that this is an area where the returns camoess very technollgy and thus economically there are only a very few applications where they will ever be practical and those are being exploited.

Camless piston engine

It shows a relatively simple design which does not require a large complex engibe setup. To meet thees standards the mass of the vehicle must be reduced as much as possible.

F1 is massively regulated in terms of what they can do. The advantage of a camless engine would be true variable valve timing — the gains would be similar to modern VVT systems but more dramatic. Check out my YouTube engien for many rotary valve videos.

Fiat have them on the Twin-Air units with some electronic controls to allow things like double valve opening during the compression stroke. Could lead to some interesting cylinder configurations.

Notify me of new comments via email. The camshaft does not directly control the inlet valves. Note that this project uses two solenoids — one to open and one to close the valve.

Where are all the Camless Engines? | Hackaday

In a camless system the only force holding the valve would be the magnetic field of the solenoid and the inertia of the valve so piston contact may not be as damaging. For decades the idea of electronically controlled electromagnetic, hydraulic, or pneumatic valve actuation has been studied, developed, and ultimately abandoned by big-name engineering firms such as Lotus gechnology Ricardo—as well as familiar automakers including BMWTechnoolgy, FordGM, and Renault.

The whole mechanism is MUCH larger. Possibly a high pressure common rail with an accumulator to work.

There are too many people who refer to things like control systems as these, on the one hand trivial things to develop, yet on the other hand this magical glue that will solve all problems.

Speed and power are regulated entirely by the amount of fuel injected. But bring it on. My most recent iteration runs very well putting out nearly double the stock horsepower. Add a power source and some solenoids. Cylinder pressure in a heavily loaded engine can exceed PSI. So, in the end, VW decided to beat the feds at their own game, when the test parameters we detected the engine ran in a limp-noodle mode, one you would never buy as a consumer but passed the tests.
