For all the Techheads amongst us..........

Very interesting! This guy is very, very good at explaining things and this new flat non-boxer engine, that he came across by accident, is certainly one that needs the explanation.
But.....by the end of it, I was thinking that an 8 cylinder version would in theory not be much, if any, longer than a 4 cylinder Wing engine. Of course, adding the conventional gearbox and clutch onto the rear of it makes it much longer but I bet someone could find a way to do an underslung box like the Wings.

Very interesting. Thanks for the info

I have to say that I do not understand when they say that it is a non boxer engine. Looks like one to me. It also annoys me to see that it is an Australian idea, with some German input, but it is to made in China.

As I understand it, "boxer" means the opposite pistons go apart and together, like a boxer punching his gloves together. Because each opposed pair of pistons on this application are locked together and shift side to side, while it is a "flat" engine, it's not technically a "boxer".

so they are going to use a gas powered engine to extend the range of an ev car. ummm I believe those are called hybrids that have been around for quite a while
And ya..made in china..no thanks

With the diminutive size and weight compared to a standard build IC engine, coupled with the lack of vibration, these could find a home in many applications; light aircraft for instance or small generator sets. The tiny twin 40hp would be perfect in a Narrowboat. Plus being able to run on a number of different fuels gives it big options.
Chinese engineering these days is, in general, as good as anywhere. Take a good look around and see how many of your tools, car components, computer parts, mobile phones etc etc etc come from there. Yeah, they can produce crap too, just like the crap that we can produce in the West.
When Ray and I had main bearings made in China some years back, the quality was excellent and 1/3rd of the price that the German factory making the big-end bearings wanted.

If you specify quality, and are prepared to pay for quality, it doesn't matter where it's made: you will get quality. But when we all started going to Walmart and Dollar General to save a nickel, the end was nigh.

Interesting. Great presentation for sure. I have to wonder about longevity. The sliding friction of that block inside the big end of the rod has to be an issue over time I would think. If I got it right they ran one for 500 hours but that is a fraction of what most engines run these days.

Yes, that is going to be the wear point for sure unless they can modify it. A conventional big-end, being fed oil at high pressure, in theory at least, never touches the bearing material. We know that is not true - cold start-up being the main cause of wear.
But that engine has a sort of wiping motion across the bearing pad. Even though there is oil being fed to it, I can't see how pressure would be maintained to separate the yoke from the crank, unless I've missed something.
