World’s first fully digital valves open up engine possibilities

British company Camcon Automotive has built the first fully electronic engine valve system, uncoupled from the crankshaft, that offers unprecedented control over the combustion cycle. On top of power and emissions improvements, it also opens up some weird and wonderful capabilities we’ve never seen before, such as giving 4-stroke engines brief 2-stroke power boosts.

> instead of being driven off the crank, each valve’s camshaft is controlled by an electric motor. These motors can rotate either way with total precision …

Car people on the forum take note.

The word “total” may be a bit of an exaggeration, but this looks very promising to me.

Intelligent Valve Technology – Petrol engine, diesel efficiency

That type of technology has been around for years and from various companies.
Here’s a video from Koenigsegg from a few years back. It should be in production soon and it’ll have great benefits for low & high-speed running.

From that link – “Nobody’s ever done variable valve timing on the exhausts, so the benefits are less well understood”
Yes they have; Toyota, Honda, BMW, etc have been doing that for over ten years. I have a Toyota version in one of my cars, the last generation of the two litre 3SGE as used in the Toyota Carina, Caldina, and Altezza. Both cams were fully variable over about 15° total movement.

The industry in some ways is so big and secretive that it takes years for information to percolate up to the surface.

We could have had this stuff years ago, if multiple obstacles were removed. ie risk, greed, secrecy….

Companies in different parts of the world could be working on the same thing, and don’t know it.

should be able to get full power with the engine running backwards (long as oil pump works) and intake stays intake, and exhaust exhaust, the idea’s handy if you need four or five reverse gears.

I like that idea of a four stroke being able to operate like a two stroke, though if you’re pumping the air (as in turbo) why not fully two-stroke?

In general, innovation in a competitive commercial environment works way better than non-commercial environments.

Mazda is introducing compression ie like Diesel, petrol engines added to its skyactiv high compression lean burn technologies, there is life in ICE yet.

Various Technologies can now move into the after sales car market.

Electrification of older cars

1 Partial 48 volt system with petrol engines, removes bits off the engine, allowing for performance improvements

2 Hybrid electric petrol systems on older vehicles.

3 Full Electrification of older cars

4 Digital Valve System that can fit onto older engines

5 Hydrogen Fuel

Other new ones? Must be heaps.

Apart from 3 where people pull out an engine and replace it with an electric motors and batteries the rest would be expensive and impracticable.

in a conventional two-stroke the sump is basically the pump housing, using the down stroke of the piston, acts like a supercharger. Regular atmospherically aspirated four-stroke uses a downward stroke also, + exhaust gas momentum to help

something elegant about piston engines, controlling individual combustions, and there’s that sine thing the crank does, gentles the piston and all to a stop, converting reciprocating motion to rotation.

an old technology, still impresses me.

Think different. Be creative.

Why cant it be cheap and practicable?

Why does design have to be expensive and impracticable ? Is the New car industry trying to put people off ?

Is it a threat to new cars? Are those with financial vested interests in new cars under threat?

Other reasons?

Yes, it’s a conspiracy. It’s actually a piece of piss and cheap as chips to retrofit a car engine with a different valve system or hybrid technologies.

Eventually.

We are talking about emerging tech, not existing tech, the two are different.

>Why does design have to be expensive and impracticable ? Is the New car industry trying to put people off ?

car manufacturers have to turn a profit, and making anything to be sold into a market has numerous liabilities that come with the territory.

the liabilities for car manufacturers are quite substantial, and you can safely assume some of what you pay is to cover those liabilities.

a lot of what doesn’t happen is because of the liabilities.

Companies can 3D print stuff now

Design times have shrunk

Assembly line tech has improved heaps

Training has improved.

Lots of improvements across the board.

Yet the naysayers still holding up their Can’t be Done signs.

Yes, note that lots of things can be made to be generic.

Things can be made to be more flexible.

3D printed. Lots of workshops can do heaps of things that they couldn’t do years ago.

But it’s not assembly line stuff, it’s after sales and you said yourself removing bits of existing engine.

You have an odd method of making statements and masking them as questions in which you presumably are interested in an answer but you are actually more interested in making the statements.

Some after market stuff is manufactured on an assembly line.

Most isn’t, just in one machine or two.

There are issues, safety, engineering requirements…

take hydrogen

We have natural gas tanks in cars

Its not much to go from a Natural gas tank to a hydrogen gas tank and add some new bits on the engine itself.

Certified people will fit the new certified gas tank in, I certainly will not do it.

My car has a gas tank, last checked a year ago by a certified gas mechanic, has a tag/ticket on it.

My brother builds cars, he has to get everything checked by relevant mechanical engineers to tick the right boxes and advice to redo things if needed etc

Which sometimes happens, so he does.

And his cars get checked by automotive electricians as well before rego
