The lubrication is an interesting point. The journals are toleranced so the oil pressure creates a hydrostatic bearing. The sliding blocks are open sided & can't make a hydrostatic bearing. Wonder how they are going to solve that....

[@vitordelima]

There is a change you can make to the Scotch Yoke so it becomes more similar to a gear (toothed) and don't need all of this B.S., but this wasn't used in this engine.

[@lassikinnunen]

If you feed oil through the crank as you do into the sliding blocks they can have oil pressure from within to keep the oil film on their surfaces. Not that it makes it better than a spinny spinny and in that path you'll have an another oil bearing transferring the rotation. Lightweight rods seems just so much easier and more sensible thing to chase for high rpm engine and look 4 and 3 cyl engines being smooth is a solved problem

[@chippyjohn1]

He has never heard of fork and blade con rods, as used in the DB605. I have been saying for over a decade that an engine designed as a generator around a set rpm and power output would be much better than a variable speed variable load engine as most cars have. You dont need this style of engine to do it though. Back in the 80's the CSIRO experimented with ceramics MgPSZ and made pistons and cylinders from the material. They allegedly achieved up to 60% efficiency.

[@vitordelima]

Adiabatic engines. There was a lot of research about this.

[@catchnkill]

It is worth mentioning that there is something similar as fork and blade con rods made it to market. There is a dual connection rods to dual counter-rolling craft shafts design. It reduces a lot of vibration. Yanmar is distributing a 50hp supercharging diesel outboard marine engine made by Neander Shark.

[@nigeltrigger4499]

The Sytech engine is not driving the wheels of the car. It is driving a generator to provide electricity. It doesn't need to accelerate or rev highly. It needs to be short in height and be very efficient (use little fuel). Are the ZZR and the Subaru engines as efficient as the Sytech?

[@foreverjim5240]

[@chinsta00]

I remember CMC/Sytech working on their engine at University of Melbourne back in the late 1990s/early 2000s. I saw their functional four cylinder prototype fitted into a Subaru Legacy for on-road testing. To be honest, with the lack of news and announcements from them over the decades, I thought they had quietly folded, disappeared and given up! Obviously they don't have the research funding of a major car company, but I do hope they made some progress over the last 20 years. P.S. I just had a dig through some old backups and I found a couple PDFs and low-res video dated 2006. Can upload if interested.

But unless you are using a factually crap engine design any engine designed using modern methods should have about the same efficiency. Its just the fact that the engine can't rev as high and needs a balancing shaft just to reach 4500rpm yet has comparable or worse results than just a conventional engine.

There's something wrong with the wrist pins, the angle of the piston wouldn't change as there's another piston attached to the other end of the connecting rod which is rigid.
