New four stroke engine with no valves.

Would this work?

I can see NO reason why it wouldn't, It does have valves, they are just differant from what we are used to seeing. The only thing I see that might be a fly in the ointment is the increase in reciprocating mass Which may require more HP to run that it saves!

That looks "iffy" to me.
Now This is something to check out;

They put one on a ford 302 and the red line went from 5700 RPMs to 14850 RPMs.

The Felik's is a actual running engine with several pic's on the net.

This one works very well, the redline can go way up because the valves don't float like a traditional engine!

The Valve design in most engines is 100 plus years old, it's time for some new designs!

It's being kept "secret" by Detroit cuz it gets 150 mpg and runs on bat poop......

You one funny Doc!  

All joking aside, I believe that the reason most of these modifications never see the production light of day is because of the "Not Invented Here" business model, which basically states thatcar companies will not use any enhancement that isn't invented by them .... no matter what the benefit (speed, safety, MPG, etc.).

Let's not forget the Wankel Rotary engine, first patented in '29

This is unique design but not very practical, and never real successful, the old Mazda engine had logevity issues and tended to smoke at 35-40000 miles because they were worn out, The were very fast cars and promoted as mini hot rods, but a car the size of a vw that got 16 mpg and could run the 1/4 mile in 12 seconds was not what people were buying in the 70's.

I haven't seen an RX-3 run under it's own power in 30 years, The RX-8 is better but still has some of the original issues!

Hi  all ,
Here another version of the new 4 stroke

I agree that the engine depicted in the original post would run, but I question its volumetric efficiency, scavenging, and internal friction.  The piston port valve system would be very inefficient at anything much above idle.  Since the valve piston is driven from a crankshaft, it will open and close slower than a standard lobed cam system.  Typically you want the valve to open and close quickly, especially at high RPM to lower the resistance to intake and exhaust flow.  Also, scavenging would be a problem, as there is a lot of leftover exhaust gas in both the intake and exhaust ports during the exhaust cycle and at the beginning of the intake cycle.  The friction of the additional pistons, would also rob power at higher RPM.  Overall, it’s a fun experimental engine, but not practical.

I see no reason why it would  not work.
As for the power and efficiency, only a working model would answer those questions.

Over the years there have been several alternative "valve" engines developed and tested, none still remain in production, with the possible exception of the rotary (Wankel).

Even 2 stroke engines and 2 and 4 stroke diesels were developed with alternative "valve" designs. Rotary valve designs and several reed valve designs.

Electrical solenoids instead of mechanical valves have also been tried.

[Robert]

The idea of no valves is a good one but a design that puts more moving parts in the system is not good, even if it works. I had a RX7 with 120k and it was still running good. But the engine design is dirty from an emissions stand point. There are some engine mfgs that use a rotary valve like a disc that opens and closes and the top of the line

Yes, I made two prototypes ... The other surprised me in plus and it was very .. I as a designer I thought about 100 hp at 10,000 rpm..but as it turned out the engine has 250 hp at 10,000 rpm. Where did it go ?? Well, you have to learn completely differently for half a year on lectures, this completely new engine.  But really worth it.

Hmm, interesting but....I designed a recip 4 or 2 stroke with only two moving parts. The basic engine is a two cylinder but is designed so you can stack additional two cyl. onto it, thereby making a four cyl. with three moving parts. Major problem....I don't have the resources to funds or build it and anyone interested so far will only finance it with a majority ownership. My answer....NO! 

It's a simple design that came to me in the "library" many years ago. And to think my wife thinks I waste my time in there. 

[98valk]

there was a lot of design work done by the majors in the '90s on 2 strokes. if it wasn't for the EPA they would be in cars today. the engines were pretty advanced and clean running.
EPA needs to go.
The best for efficiency is a small diesel engine running a generator to supply power to the electric drive system, prototypes by the majors were getting 100mpg.
 unless we find that vein of dilithium crystals which will be more efficient.

So many people waste a lot of time and money on building new engines .. But I call ie Feliks ie happy.

No turbo , swirle   

Now why I summoned Riccardo..Ricardo developed fairly firebox V-Comet .. Especially in diesel played a significant role - helped make a high speed diesel engine .In my also applied the swirl chamber, knowing about its merits.

Maybe a bigger Valk engine for cars?  My wish I could ride or have J Leno's  Jet bike. That would be fun.

Or maybe a two-wheel car would do ... There's no need for an differential and anything .. see the Segway
There is no steering wheel, and what's the return .. because let's say on wheels 1.5 meters in diameter ... for every trimmer will come ..

See: Subaru. Make this motor, and have for years. Also Corvair, Porsche. Nothing really new about the Valk motor.
