Re: Sterling Engine not running

I think it's complaining about being locked in a cage, go on it's not a Lion. Seriously though I think you might need to take out the power piston and clean the oil off of it, and wipe out the inside of the cylinder. Did you actually find where the unusual noise was coming from, was it the bearings,...

Re: Problem Rider Ericsson model

I would have thought that the valve opened when the internal pressure dropped below the atmospheric air pressure, I could be wrong, but I'm just going by a friend's vintage Heinreci motor. You can seethe snifter valve on the left , just above the fire box, a small brass fitting below the water pipe....

Re: Need advice buying my first sterling engine

Generally I would say that a Stirling Engine power grid is a different technology to a diesel based one, With a diesel power unit you start up and use the power as required, then shut down. With a Stirling based power supply, you would run it full time and charge a battery bank, this bank can be rec...

Re: Need advice buying my first sterling engine

A 30hp STIRLING ENGINE is going to be quite a large machine, the well known Philips gen set produces about 200 Watts, it's around the size of a 1 to 2 KW IC gen sets, Co generation systems like the Whisper Gen produce about 1 KW of electricity, and 5 KW of heat to be used for central heating or dome...

Re: 18th international Stirling engine conference video

Did any of the forum members attend the conference, if so perhaps a few words, maybe just what you got in the goodies bag!

Re: Design and Manufacture of Beta Stirling

The cooling system on a Stirling Engine is possibly more important than the heating, that's why most of my motors are water cooled, even one of my small ones has water in a hopper. That motor has a power piston of 5/8" diameter and a stroke of 1/2". the displacer is 5/8" bore by 3/4" stroke. Ian S C

Re: Problem Rider Ericsson model

The breather valve/snifter valve as far as I know is there to bring the pressure back to atmospheric as it tends to drop a bit over time. How good is the cooling system, motors with pumps often pass the pumped water through the water jacket, and if you pump from a fairly small container, and back in...

Re: Problem Rider Ericsson model

Put the heat up, and take up the extra power with the water pump, these motors are designed to work with a load, also more interesting to any onlookers. I have one BETA motor with a pump, it draws the water from a container on the floor, about 3ft, it passes through the water jacket on the motor, th...

Re: Problem Rider Ericsson model

Test 070 (640x480).jpg Hi Rik, did you build the Rider motor your self, and was it a kit of castings? For a 2" motor I don't think you have a big enough flame, I think you will find it needs quite a bit bigger than a cigarette lighter. My motor of similar size uses the burner from a camp stove.

Re: Alpha vs Beta

No the ALPHA motor is a different motor, the hot and cold cylinders both generate power, where as the other Stirling type motors have the one power cylinder, and use some of that power to drive the displacer. My second build is based on Dyna, a BETA motor designed by James G. Rizzo, it has a bore of...

Re: Alpha vs Beta

I can assure you that an ALPHA motor has a higher power to weight over either a BETA, or GAMMA motor. The swept volume of the cylinders of an ALPHA is equal, ie 1:1, I'v only built one unpressurised Ross Yoke ALPHA motor, 35 mm bore x 22 mm stroke, about 5 Watt at the crankshaft. Ian S C DSC01351.JPG

Re: Wood burner Sirling fan engine

My GAMMA one uses the 1.5 : 1 ratio, and the Ringbom one is about 2 : 1, but it sorts out it's own ratio depending on the load.

By the look of their Facebook site they seem to still be in business, but there is nothing much about sales of their machines.

Re: Dual stirling generators electrically heated

Electric al generation by a Stirling Engine of (say) 1Kw might at most develop .75 Kw to .8 Kw, a heating element might have a similar efficiency, producing say .5 Kw of heat, and the engine might take up 50% of that, it ain't gonner work mate. But an electric powered Stirling Engine is a good demon...
