Dieselisation

Dieselisation (US: dieselization) is the process of equipping vehicles with a diesel engine or diesel engines.^[1]

It can involve replacing an internal combustion engine powered by petrol (US: gasoline) fuel with an engine powered by diesel fuel, as occurred on a large scale with trucks, buses, farm tractors, trains, and building construction machinery after World War II. Alternatively it can involve replacing the entire plant or vehicle with one that is diesel-powered; the term commonly describes the generational replacement between the 1930s to 1970s of railway steam locomotives with diesel locomotives, and associated facilities.
