  • Guiberson 9 cyl radial diesel

    This interesting Guiberson 9 cylinder radial diesel engine from the early 40's was one of the exhibits at the recent David Hack Day at Toowoomba, SE Queensland. From a little googling, I gather these engines ended up in tanks and boats as well as aircraft. There is a good article from the period here. http://www.enginehistory.org/Diesels/Ch3.pdf

    That is cool, I think one engine choice for the American tanks was a big Chrysler.......CRS about some others..........I do recall one comment by an old vet.......it was one of the worse jobs, sitting silent in a freezing metal compartment for hours during winter in Europe.........then the relentless heat of Africa..........we owe a lot to those men...........

    Not many air cooled diesels around........Duetz is about the only other that immediately comes to mind..........
    Opportunity knocks once, temptation leans on the doorbell.....

      Perkins is also air cooled but in my opinion not as good as the Deutz.

        Thanks for the photos Bob. I remember seeing a short video of this engine not too long ago, they had a rather unique way of starting this engine with a rope and an old truck.
        Probably a little hard getting parts for the original shotgun cartridge starting system.

        Blackforest, although I am familiar with the Deutz air cooled engines, having once driven a logging truck with a 12 cylinder Deutz, I wasn't aware of Perkins being known for it's air cooled diesels, all that I have seen were water cooled.

          Saw one and heard it run years ago at an antique machinery show. The 9 cylinders (odd number) gave it an odd sound at idle. The owner used a shot from a tank of high pressure nitrogen in place of the powder cartridge for starting.

            I have never heard of a Perkins air cooled engine either.I`ve heard of Petter,Lister,Ruggerini and a load of others but never Perkins.

              Radial engines use an odd number of cylinders per bank in order to get an even firing order*. A 9 will run 1-3-5-7-9-2-4-6-8 for its firing order. Or in this case compression ignition. Packard as far as I know built and flew the first diesel radial in 1928. Walter E. Lees and Fredric A. Brossy set an endurance record of 3 days, 12 hours and 33 minutes in 1931.

              *There have been a few exceptions to this. Wright designed a couple of engines with even numbers of cylinders per bank. One was a 12 with 2 banks of 6. of the designs they were working on I know one was air cooled and one liquid cooled. Bristol also worked on a 16 cylinder radial, the Hydra. Also there are some modern 2 stroke radials that have 4 per bank but then the timing issues go away. Also in the even number of cylinders per row engines the cylinders were not offset from one bank to the next. An 18 made up of two 9 cylinder engines will have the second row of cylinders offset 20D from the front bank for both cooling and timing reasons. link is to a model of the Bristol

                Interesting link Spin Doctor, thanks.

                A very intricate and complicated project to be sure, and he's doing it largely with a round column mill!
                I love it.

                  What an interesting read, could not believe that it only weighs 650 pounds, likely bare but still light for the size of it.

                  Also fuel for 6¢ a gallon for the test flight

                    Lycoming also made an air cooled inline four, I replaced one with a Duetz five cyl on an old genset a few years back.

                      The technical description in the link shows that this was really a high quality engine. I notice that they were built by Buda Diesel for tank use. There was a Buda Diesel plant South of Chicago when I was living there.

                        Large Engines

                        There was a tank engine combo made from five Chrysler industrial six cylinder engines on a special mount. Nordberg made large radial engines powered by natural gas that were direct connected to D.C. generators for the aluminum smelting industry.

                          JRW, am sure I saw that some time back, weren't they using the slant six engines?

                            Chrysler Multibank WWII secondary Sherman Tank engine...

                            Five 251 CI flathead 6 engines joined together. 1253 CI total. 425 hp at 2,850 rpm 1060 ft lbs of torque. weighed 5400 lbs.

                            Bottom 2 engines were horizontal, Top engine was vertical, and next 2 were at roughly 45 degrees.

                            Long before Slant Sixes...

                            Was actually fairly reliable.... But most were sent out as Lend Lease...

                            Was a better engine to drive, due to low end torque that the Radials did not have.

                              Beguns says it all. The slant six did not arrive until decades later.
