Institution of Diesel and Gas Turbine Engineers Institution of Diesel and Gas Turbine Engineers The Institution of Diesel and Gas Turbine Engineers is the professional association for engineers in the diesel and gas turbine industry in the UK and internationally. Diesel engines and gas turbines are broadly related because they use a similar thermodynamic cycle, and both are often used (and interchangeable) for power generation for heating and electricity in large installations. It was established in 1913 as the Diesel Engine Users' Association. It changed to its current name in 1984. It is based in the north-west of Bedford towards Brickhill at Bedford Heights"" Types of membership
