Looks like I ran into my limits of the English language. I mean that the engine breaths more than sufficient air to burn more fuel. It's as...
Thanks to you guy's, the Lister engine has caught my attention. I found almost all technical information I need, I'm missing only valve...
Just perfect. I have spend some time on the inter-net locating a supplier for those parts but no luck so far. Before starting the actual build...
I have downloaded the drawings. Valuable information- again! Thanks. Before I start looking for parts to scan&draw, is there a reason why I...
For a starter? Deutz engine parts. Not Ø136 but Ø128 piston size. Bore/stroke 128mm/78mm Displacement: 1003cc or 61.2 cu inch
Completely forgot about that. As I like to use an engine at 500 to 1000 rpm, I need also a much taller prop. (or gear-box?) But, it all boils...
From what I know at this point, I would be surprised if I need such a big flywheel that it becomes an issue. Nevertheless, the flywheel is going...
OK, this clears all. I just had an other kind of vessel in mind.
The question that intrigues me the most is how much the rpm of an engine is responsible for the BSFC figures. On one side we have the fast...
Hi Barry, These figures are confusing me. At first glance, your vessel need only 40 HP for 6 nmph and 80 HP for 8.8 nmph. What fuel is...
I agree that normal operating conditions at best BSFC number is the smartest thing to do. I found a very interesting paper on 'downspeeding the...
Up to 100 HP I have my own test bench (water-brake). I was just surprised of the size and power of these slow running marine diesels. The...
Thanks! I had no idea.
A few day's back I was asked in an other thread about the specific fuel combustion of a 'modified' 4-stroke cycle. We know from manufacturers...
It all depends on size and engine speed. There is a total different approach. On slow running diesels it's possible to filter out the oil....
Double power .. or half displacement .. or half the speed .. or a combination of a bit from all. (compared with a normal aspirated engine)...
Yes, I can't rule out that simple reed valves can do the job. The picture shows the crank-case of a flat 2 prototype. You can see the holes...
Yes, a set-up as shown in the drawing (without one-way valves) is for one ore an undefined number of isolated cylinders only.
Interesting reading. You have the real thing and besides that, the 'valve' controlled 'Atkinson' cycle as used in Toyota engines. It explains the...
In this case, no. The energy that forces the air into the cylinder during the second phase is lost, just as any other type of blower you may think...
