Hi everyone,
I feel like I must have forgotten something from college but my old textbooks/notes aren't turning anything up. Neither is my search-fu or bearing manufacturer documentation.
I'm specing a bearing for a roller follower in a reciprocating mechanism (designing for 50 Hz max...
I'm a huge advocate of self-teaching. I think it's the single most valuable skill I learned in engineering school. You can always drop in on a place like this to ask questions. Personally I answer a lot of questions on Quora and reddit about engines as well. If you shoot me an email at my...
tbuelna you're a clever man because you've hit on a key concern. Theoretically the rods are always in tension, at least under normal operating conditions. But given a misfire or loss of combustion the forces go into compression. One of those pesky real world concerns that are easy and tempting...
Wait, I didn't say it was an inline four, did I? Not that I can in my posts. It's a 2 cylinder opposed piston engine, you got that right. But it has a single crankshaft and longg rods in tension to get to the outer pistons. So the piston is technically 3 throws but 2 of them are identical as 2...
Hello AutoZoned,
I was the engine and drivetrain leader for a Formula SAE team at a college with very little internal combustion engine or automotive resources. The closest research or expertise was in the combustion lab where they were performing fuel studies, but it was mostly applicable to...
Hello everyone, thanks for all the suggestions. We actually made some really good progress on the issue last week. I pulled a conrod, hung it, put accelerometers on it, and hit it with a hammer. Great fun and the simulation guy I was working with loves validating his sims with real world data...
Tmoose, I considered it but the company is pretty serious about IP and I play it safe. Also, the more important aspect (for me) is becoming a better engineer and expanding my skillset. Not looking for anyone to do my homework for me :)
Yeah you've got the right idea. 4 pistons, 2 cylinders. The...
Greg,
I'm in the US so that course probably is unfeasible for me. But I'll look into other seminars in the area.
Hemi,
Unfortunately I'm not involved in design. If I were I wouldn't be nearly so worried about vibration, it's a very unique and experimental engine layout that hasn't lent itself...
Hello everyone,
A little bit of background: I'm a recent grad (mechie BS) with a decent amount of engine experience for my age and position. Formula SAE powertrain lead, and did a combustion engine research project. I'm familiar with a lot of engine basics (I've read a lot of tech papers...
