A Fiat foi a primeira marca a comercializar um automóvel com esta tecnologia. Estreou-se em 1997 no Alfa Romeo 156.
Em 1997 já era o MultiJet, antes disso desenvolveram o UniJet e em 1986 o id (ijection direct ?) no Fiat Croma TDid.
"the Fiat Group set an important new record in the field of diesel engines, made possible by the huge amount of expertise accumulated since 1986, when the Croma TDI was launched, the world's first direct injection diesel-engined car."
(...)
"One problem remained: the excessive noise made by the engine at low speeds and in 'speed transients'. This is where the history of the Unijet starts, or rather the search for a more evolved direct injection system, which could drastically reduce the problem of noisy combustion. After a few years, this research produced the Unijet"
(...)
"Pre-industrialisation of the Unijet, the system developed by Magneti Marelli, Centro Ricerche Fiat and Elasis on the basis of the Common Rail principle, began three years later, in 1990. This stage was concluded in 1994, when Fiat Auto decided to choose a partner with great experience in the field of injection systems for diesel engines. The project was therefore sold to Robert Bosch for the final part of the work, i.e. completion of the development process and industrialisation."
... e só então, depois disto, aparece o MultiJet no Alfa Romeo 156:
"In October 1997, eleven years after the Croma TDI, another record-setting car went on the market: the Alfa 156 JTD equipped with a revolutionary turbodiesel engine that gave hitherto unimaginable results. The cars equipped with this engine were incredibly quiet, with a sparkling response on a par with that of a petrol engine and performance levels that were 12% higher than those of a similar pre-combustion engine, as well as 15% lower consumption."
"Now it is the turn of the second generation of JTD engines, the Multijet multivalve units"
