Ed Marshall considers himself very lucky to have spent his entire working life playing with engines. First with BP Research where he carried out a number of programmes investigating the relationship between engines and their fuels. Then, having been elected to a Fellowship at Cambridge University, BP kindly offered him a sabbatical, on full BP salary, to enable him to take up the Fellowship and continue with his research. Eventually he returned to BP to set up a facility to measure flame speeds inside a working engine using a split-beam laser. His fuels experience covers a large range of engine types from Stirling to Ceramic Diesel. He spent 10 years running his own consultancy, working mainly for the Oxford College of Petroleum where he organised and ran fuels training courses for Oil Industry personnel around the world. He relaxed by cruising the English canal system in a narrowboat. Ed has been a member of the Newcomen Society Activities and Visits Sub-Committee, and has organised a number of weekend visits to areas such as Hull & Humberside and Northern Ireland, a study weekend on the subject of ‘Glass’ in St Helens, a study day at Bletchley Park, and a visit to the ‘Coalite’ plant at Bolsover together with numerous short visits in the London area. He was a member of the team that organised the successful ‘Piston Engine Revolution’ conference held in Manchester in 2011. He has written and presented three Newcomen Society papers; edited a book on ‘Motor Gasoline’ published by The Royal Society of Chemistry and has published numerous papers in the IMechE and other technical journals.
