History of the diesel car developments (Mercedes-Benz, BMW, Peugeot/Citroën, Fiat, Alfa Romeo, Volkswagen Group) There were also small diesel engines produced in England by British Leyland and Perkins. For reasons of economy the petrol BMC "B" series engine was dieselised and produced in capacities of 1.5 and 1.8 litres.

Unlike other RDC sets, however, the trailer's diesel engine is used exclusively to provide head-end power for the entire three-car set, while the engines in the driver car are used for propulsion. To prevent dependency on the trailer's engine for cooling, the cooling fans of the driver cars
