RE: Air Leaks...do you really need to seal your engine ?

Nah that was not my intention.
For ease of tuning and bearing life i think it's a good idea to plug that hole.
You _might_ see a small power loss from increased viscous friction thoug.

RE: Air Leaks...do you really need to seal your engine ?

That hole would provide a substantial "vacuum" in the groove around the crankshaft, when running high rpm and small throttle openings.

Apart from that, I'm with downunder on crank sealing,...

RE: Tuned pipe help needed Super Tigre GS 45

Not a problem at all :)

I actually have some own experience of just that, have been racing F3D since 1995 or so.. ;)
Downunder is about right I'd say, even though I would add some on that...

RE: Tuned pipe help needed Super Tigre GS 45

A bit of topic, but anyway..
The quote above is probably true for F2A, control line speed, but:
F2D, control line combat, do not use tuned pipes.
F3D engines are normally "on-the-pipe" before...

RE: RC turbo design problems...

Yes, I'm absolutely sure.
What I'm also saying is that it's a lot harder to get it working on a model size engine, with it's very simple carburettor and glow plug ignition.[8D]

RE: RC turbo design problems...

Well, I'm not aware of any two-stroke turbo charged snow-mobiles using direct injection into the cylinder. I have only seen carbuetted(spelling?) and plain EFI.

savagecommander,

Since turbos are successful on two-stroke racing snow mobiles (see earlier post in this thread) I think you can safely assume that the principle works, right? ;)

Good luck with your simulations, but watch out, it can be seriously addictive ;)

It can model two-stroke engines.

Look under Data - Cycle Type ..it's there.

Have a look at Lotus Engine Simulation, there's freeware version available for download that's limited to single cylinder simulation.

Good luck :)

TooSlow2Care,
I don't have any own experience with turbo charged two-strokes, so I cant really tell how bad the turbo would be.
You don't need reed valves for it to work though.

RE: Glow plug ignition timing

I have to say that a glow plug ignition is a bit different from HCCI.
As I know it, combustion in a HCCI engine is homogeneous, and starts at mulitple ignition points.
The combustion in a glow...

You are absolutely correct, as I said earlier.. it was a long shot asking ;)
Unfortunately I'm not capable of creating the model myself.. I'll have to stay in my current line of work ;)

I fully agree on the effects of running too lean. I'll just add that theres no throttle on the engine I'm simulating ;)

I'm not sure how to show you the simulation. Its based on the book "Design and simulation of two-stroke engines" by Gordon P Blair. I can try to post some results though.

Not the same timing that's discussed in the other thread, "Glow engine Timing" ;)
