The rattling is caused by the vibration of the engine. The "bench" is what's left of a really old 10MB H-P hard drive. Made of metal, there are several joints that are loose. I may fix it one of these days ....... Maybe. :-)
It runs slowly only because of the heavy flywheels and long stroke. If I try to run it at up to about 1,200 RPM, the fuel system begins to not be able to keep up. Sort of self-limiting.
I have no idea how much the reciprocating parts weigh. When I designed the crankshaft, I used steel I had on hand and made the counterweights as large as the material allowed.
It must be balanced pretty well because the only shaking is horizontal, due to the reciprocation, unavoidable in a one-cylinder engine without counterbalancing shaft.
Sorry I'm late with the answer to your question! Having apologized, I don't really have any idea of how much the piston and rod weigh. Rod is of steel and piston is of cast iron so they aren't light although the rod isn't as heavy as it looks due to the fact that it is hollow (pipe).
I'd venture a really off the wall guess at about five pounds. As it is, it shakes very little so I don't think I'm gonna try to improve on it.
Where is the governor and where u regulate the speed?? and emm whats the different between hit and miss and this one??? and also this: where IS the cam?
The Homebrew Hvid governor is located behind the small sprocket between the frame sides. The speed is constant, regulated by adjusting a nut on the governor shaft.
In the hit-and-miss, the mixer (carburetor) does not have a throttle plate and runs wide-open all the time. The governor latches the exhaust valve open when governed speed is reached.
On the Homebrew Hvid, the cams are located between the side plates of the engine frame.
I am amazed at you ingenuity! That is an amazing engine. I love engines, and want to build some. I have to say your diesel engine has inspired me. A+++++
It's a very nice looking engine, runs well too. I like it.
However, I'm puzzled when it comes to 0:57 - the commentary, to be exact - what is causing the rattling?

Bench! that was the word that puzzled me. For some reason I kept hearing "b*tch".. Dear me.
Metal benches are real treasures... Hard to get these days. Of course you can build your own, but one always finds an excuse not to... :-)
Great engine anyways, and I for one don't mind the rattling.

seems to run well. i like low idling engines.

how much does the rod and piton weigh? do you have plan on balancing it better?

Its not the highest reving engine but i guess that means less wear on the parts.

The Hvid fuel system isn't conducive to high revs. The system on this engine starts falling apart at about 1100 RPM.
In any case, if it ran too fast, it wouldn't be as interesting to watch.

Your wright low reving engines are more intrasting to watch.

how you time the valves?? and does it have a governor?
SthealthRaider 2 years ago
The cam timing is just the normal setup for a 4-cycle engine. About 210 degrees for the exhaust and about 190 for the intake.
Because of the small headspace on a compression ignition engine, the overlap is almost non-existent, probably only about 5 degrees on this engine.
Yes, it does have a governor. All compression ignition engines require one because there is no other way to regulate the speed effectively.

Very cool engine Elden! Your valves and chain timing gave me some ideas for my half-brew engine (old air compressor turn into an engine) Take care!
