ItaliaspeedTV - Fiat Punto Evo - Multijet II technology

Description

All Fiat Punto Evo diesel engines are equipped with the next-generation MultiJet Common Rail injection system. This highly advanced solution can control high engine pressures (up to 1600 bar) without being tied to engine speed or the quantity of fuel injected. In the 1.3 MultiJet Euro 5 versions, the system uses innovative common rail injectors that, thanks to a balanced hydraulic servo-valve, are able to more precisely control the quantity of diesel injected into the combustion chamber, with a faster and more flexible sequence of injections than was previously possible. By reducing the amount of time between injections, these injectors optimise fuel introduction to the chamber and therefore make the diesel combustion process more gradual, with positive effects for consumption, emissions, NVH and handling. In fact, the new common rail injector on the Euro 5 engines cuts consumption and CO2 on the approved cycle by around 2%, while at the same time reducing harmful emissions. The second-generation MultiJets are therefore the latest development in the Common Rail injection system which, after the JTD (1997) and MultiJet (2003) engines, gives the Fiat Group yet another first in this field. The 1.3 MultiJet is available in Euro 4 (75 and 90 hp) and Euro 5 (75 and 95 hp) versions, the latter coming with a particulate filter and Start&Stop as standard. In addition, turbo is carried out either by a fixed geometry turbocharger (75 hp) or a variable geometry turbocharger (90 and <b>...</b>
