Caroilne Diesel Engine
piston and sleeve rings

Piston and sleeve sealing design.

This is how I am moving forward.

If you click on the photo you will see a model engine and you will see the piston travels over the ports of the sleeve.

Now if you have a look at my picture above I will explain it.

For a diesel engine with the piston almost reaching the junk head the ports will have to travel over the piston rings, but not the oil ring.

1 Piston oil ring

2 Piston ring # 2

3 Piston ring # 1

4 Cylinder bottom # 2 sealing ring (oil ring?)

5 Cylinder bottom ring # 1

6 Cylinder top ring # 1

7 Head ring # 1

8 Not shown head ring # 2 ?

I am at the moment looking at using a four-stroke piston with two stroke rings and modifying the piston to stop ring rotation.

Reason being that the rings will have to travel over the ports.

have a look at Toms sleeve valve engine

click here for vidio

I have two options here:

1. I can use conventional rings for all the applications, but then I will need to make the sleeve thick to carry the rings.

2. I can find rings that work in, instead of out. If I can find this tip of ring then I can have really thin walled sleeve's

Paste this link, on this link you will see a Bristol Hercules sleeve and rings.
