What's amazing to me is the equipment he uses. Not a cnc machine in sight, all by hand. I can't even imagine what he could build if he had cnc machines to use. Awesome work.
Great work a while back you made a horizontally opposed twin engine, but both pistons shared a crank pin and I pointed out that it wasn’t truly a boxer. I had no doubt that you could build a boxer and I’m glad that you decided to do it. Awesome work keep it up.
I repair bikes too but, man, if I had just 20% of the machining/precision skills Dan has, I'd be over the moon!! Good job Dan, I've been watching your channel for a long while and your work just blows my mind 💪🏼💪🏼
I didn't think the 2t boxer could have a shared intake because one side would greedily suck everything first due to any slight port asymmetry. The advantage of the 2t boxer is the perfect balance (the rocking couple is quite marginal) and the split bearing load. So instead of reservicing one big engine frequently, you replace two sets of stuff but not as often, nominally lasting twice as long, more like time and a half irl. It looks great!
I have been following Le Dan for many years now. Was not sure that a 2 Strike Horizontally opposed Twin could run with a common Crank case. I was not sure if the crank case compression would work. It does when the pistons are on the "downward stroke". Also helps with p[ort scavenging. Well it does an smoothly at that. Good one Dan. Next is to see this engine in a bike. Keep up the "back yard Engineering". you inspire us. Derek from, Durban, South Africa.
Thats a grate idea 💡! Boxer 2-stroke is one of the lowest vibration 2 cylinder engine designs. (Both cylinders fire at the same time, in opposite direction)
You should either narrate or put subtitles to explain what you’re doing and why. It’d be a far more effective teaching tool than simple observation, still this is very interesting and informative, bravo master mechanic and machinist.👏🏽👏🏽👏🏽
Tuyệt phẩm! Một nhân tài xuất chúng của VN,rất tiếc là sự thông minh và khéo léo lại không được phát huy khi còn ở VN- Mong rằng các tập đoàn sản xuất xe gắn máy ttrên Thế giới sẽ xem được những sáng tạo của em! Chúc thành công ❤
@@nguyenphan8819 biết là có mẫu động cơ ra gần 100 năm nhưng hỏi thử thằng kỹ sư này kia có bằng cấp này nọ thử coi thằng nào tự 1 mình làm được việt nam chỉ có vài người làm thể loại ghép máy động cơ thôi nhưng làm đơn giản hơn ông dẫn nhiều chỉ thấy duy nhất là ông này làm đẹp và công phu rất nhiều
Mấy cái này chỉ để thỏa mãn niềm đam mê thôi, chứ không có gì mới với thế giới cả. Công nghệ động cơ phát triền hàng trăm năm nay đã qua thời kỳ các động cơ sơ khai này rồi. Vậy nên chả tập đoàn nào nó nhòm ngó đâu. Các bạn đừng ảo tưởng.
I have a few of those Robin engines and I love them, seeing you do this makes me want to do the same thing. you should build 2 expansion chambers for it now
The holding bolts of the cylinder and crank assembly should be heavy as it is aluminium, we may see this on the road soon..you guys are crazy.... nice work..
Dude, why and how are you not making engines for a major company yet ... You're doing the same work as a whole Development and Engineering team with less then 1/4 of the tooling a team of Engineers and Machinists has at their disposal or the budget, granted this is smaller scale work but clearly you've got the mind and talent for it.
Sachs Wankel engine for the next project. Good luck finding parts, or just make it. Machine some rotor and make the apex seal in the shop your self.... 🔥
Air cooled motorcycle engines usually do not have forced air cooling (i.e. a fan). The cooling fins are large enough to cool the engine when the motorcycle is moving.
