© Science Museum / Science & Society Picture Library
Model (scale 1:8) of the original crude oil automatic ignition engine designed by Herbert Akroyd Stuart (1864-1927). Stuart was a mechanical engineer and manager of the Bletchley Iron and Tinplate Works in Buckinghamshire. He was the first person to succeed in building an oil engine in which ignition was sustained without the use of ancillary apparatus. This model was made to Stuart's directions to represent his engine as patented on May 8, 1890.
