In 1933 the well-known firm of Chapman and Sherack, Erskineville NSW, introduced a 15hp, 2 stroke diesel . It had petrol start for easy cranking, as did the earlier IHC tractor diesel engines. The bore was 7.5 inch, stroke 6 inch. 100 to 600 rpm. They were advertised up to 1941, as far as I can find.
What I would like to know is how successful they were, does a collector have one or anyone seen one running?

I was given a brochure - copy from John Forrest years ago on this engine. John said it was a low compression dieseling engine which maintained combustion by having a special type steel 'frying pan' suspended on the piston which would continue to perhaps glow red hot. So long as the engine didnt idle for too long. These engines were advertised to run on any kind of oil including vegetable oil! I went to Erskinville a few days ago to 26 clara St where the factory was. I took a picture, unfortunately there is only a block a flats there now :'-( On the bright side though; i was bringing home a Chapman Greyhound 6\8HP shipped from NZ! :-) |

The Chapman diesel was described as being a high compression type. It was reported that it could be started on a spoon full of petrol, and when the revs mounted, switched over to high compression and diesel injection. If there was some type of surface ignition, the engine would have needed to be run for a few minutes to get any part red hot. I have never heard of a surface ignition engine with a moving hot spot. The injection system was conventional Bosch pump and injector as used in other compression ignition engines. Any diesel engine will run on vegetable oil.
The "frying pan" story is interesting, but I would need more proof before I believed it.

Greg, the greyhound has covered some sea miles since it was built, average fuel consumpion per mile would be the best for any greyhond ever made |
