Description

The Diesel engine type 305 was developed by FIAT, in the early '50s, starting from the petrol engine type 105. Initially it was used for the light truck FIAT 615 N and, in 1953, for the FIAT 1400 Diesel, making it the first Diesel engine produced in Italy for passenger cars. From the same year the engine was also used for the light off-road FIAT Campagnola Diesel. The 305 engine was built in various versions with improved performance. This model has been partially sectioned for didactic purposes.
