    I wish I could get my hands on one of these machines. I have so many uses for them, its unreal.

      🔴 What Is Islam? ⚠️
      🔴 Islam is not just another religion.
      🔵 It is the same message preached by Moses, Jesus and Abraham.
      🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
      🔵 It reminds us that since God created us, no one should be worshipped except God alone.
      🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
      🌍 The concept of God is summarized in the Quran as:
      📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚
      🔴 Becoming a Muslim is not turning your back to Jesus.
      🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

    Fascinating, I did not know that this engines where produced that late in the 1930s...

      Before pressurized town water, homes might have one of these pumping water to a cistern in the attic for gravity fed plumbing.

    Anyone knows what is the power output of these and their efficiency? There isn't much data I can find about these

    • @riderericsson
      @riderericsson  3 роки тому

      Are you asking about these particular engines or stirling engines in general? These old ones were low powered (fraction of a hp) and not very efficient compared with modern pressurized stirling engines.

    What is the lowest warm-up time to start the engine?

    • @riderericsson
      @riderericsson  2 роки тому

      The larger the engine, the longer the warm-up time. I can't remember exactly, but for these I think it was around 3-5 minutes.

    • @riderericsson

      engine on left is 3-inch bore; right is 3.5-inch. Both with strokes approx. 4.5 inch.

      @@riderericsson Thank you for the reply , I am trying to form an idea of the relationship of piston size to power output as design criterior. May i ask if you know the swept volume ratio ie: rev stirlings 1.5/1 displacer / power ? of these engine ?

    Beautiful engines! They work in acetylene with carbide?

    • @riderericsson
      @riderericsson  6 років тому +2

      No the burner uses kerosene which is vaporized by the heat of the burner head which must be pre-heated before starting. The engine also pressurizes the fuel tank.

  • @zakathzakath6184
    @zakathzakath6184 6 років тому

    Nice engines.How much hp they produce,rpm?How much consumes kerosen per hour?

    • @riderericsson
      @riderericsson  6 років тому +1

      Probably only a fraction of a hp at about 2-300 rpm. I'm not sure about fuel consumption, but these are old and very inefficient compared to modern pressurized stirling engines.

      riderericsson Can you test the kerosene stirling engines only putting 1 desilitter kerosene in it and that way we can see how long it will run.

    Very interesting, the smallest, with red flywheels, even more original.

    • @riderericsson
      @riderericsson  6 років тому +1

      The "smallest" actually has a larger piston size. The 'double throw' crankshaft arrangement of this engine was also copied from Heinrici "HM" type engines introduced in Germany in the 1920s.
