Do you assume there is a patent issued? If so, people can look it up. Otherwise one would need to understand the purpose and operation of the device to make a reasonable response. Cylinders of metal existed, crooked metal shafts existed, flammable liquids existed, sparks could be made - why was the internal combustion engine a big deal. Oh, the particular interrelationship makes a big difference. – George White Sep 17 '22 at 23:54
