Listeroid Engines / Re: Is a Metro 6/1 also an 8/1
« on: May 30, 2007, 03:08:02 PM »
JP,

That's a very interesting question. Obviously the people who really know the answer are the manufacturers. However, you might not be able to trust the answer as they would like to charge more for their higher power engines.
I know of two suppliers who's 6hp and 8hp engines are exactly the same - confirmed by them. One of them will even provide warranty for their 6hp engines running at 1050rpm producing 10hp. I think they use well-balanced, high quality casting flywheels.

Evidence to the contrary comes from Lister - their 6/1 engines had different cam profile/timings than the 8/1. I don't know if there are other differences.
I would imagine that the injection timing could be optimized for each speed.

Listeroid Engines / Re: Majorly overheated Listeroid, now what!?!!!

This is a very interesting scenario. It sounds like the colant (water) vacated somehow.
Can you tell us if your piston is cast iron or aluminium.
Cast Iron is very tolerant here, and does not sieze in a permanent manner under these conditons - aluminium is different.
You may also want to check whether your engine has a chromed cylinder. Honing that will give some interesting challenges.
I'd be interested to see if there is any scoring on the valve stems. There's not much in the way of lubrication on those, so excess heat could make things unpleasant.

Listeroid Engines / Re: injection pump and exhaust update.

Carl,

Can you tell us the arrangement/configuration of the T connector? Did the exhaust go straight through to the gas bottle, or straight through to the muffler, or straight through to neither?

Thanks,

Does anyone know of any chinese companies supplying marinized diesel singles?

I came across one engine on ebay (110092922002).

Mike,

Can you tell us if the GM90 6-1 is a direct or indirect injection engine?

Other Slow Speed Diesels / Re: Uganda Need Changfa or Lister style engine for Orphanage

Phil,

If there is an interest in burning vegoil in this genset for the Orphanage and it is more of a charity venture than a commercial one, I would consider providing a vegoil burning genset, if some of my costs could be covered.
Contact me off-line.

Engines / Re: Oil cooling for Listeroids?
« on: March 13, 2007, 12:53:42 AM »
I am cooling my Listeroid using oil.
My intension was to see what would go wrong, and whether I could stop the head gasket leakages.
The leak is just the same, but now I get some oil lubrication on the valve stems - not something I would want with Waste vegoil.

Can you tell us how you were cooling your engine during these tests? One of the problems of running engines slower than designed is that they run too cool - something very bad for used engine oil fuel.
