Fiat 1.9 JTD Twin Stage Turbo

Fiat Press Release:

The 1.9 JTD TWIN STAGE TURBO is the latest development within the FPT Diesel Family with a specific power close to 100 HP/l.

This engine has been developed with the target to add to FPT Diesel portfolio an engine with high power & torque density, excellent low-end-torque and already capable to meet the future Euro 5 emission standards.

Based on the current 1.9 JTDM 16v engine, the engine will be available in two versions: - 180 HP @ 4000 rpm - 190 HP @ 4000 rpm

both with 400 Nm torque @ 2000 rpm.

The engine will be sold to both captive and non-captive customers, with the higher power output reserved to FGA applications.

The low-end-torque has been improved by 50%, with 300 Nm available already from 1250 rpm.

These outstanding performances have been achieved basically through the introduction of an advanced charging technology, such as the Two Stage Turbocharger, together with proper design changes, to increase the thermostructural resistance with increased peak cylinder pressure (up to 180 bar) and exhaust gas temperature (up to 800 deg. C).

The Two Stage Turbo (TST) technology allows to remove the usual constraints that the engineers have to face when the size of the turbocharger must be selected, that usually means to accept a compromise between power and low-end-torque.

Maksimalan obrtni moment od 400Nm, a već 300Nm raspoloživo na 1250rpm. Maksimalna snaga 190KS.

Veri najs.

Inače, vest je od sredine 2007. godine.

The two stage turbocharging enables the new engine to combine the instant response of a small turbocharger at low speed and the elimination of ‘Turbo lag’ provided by large turbocharger while the second stage provides ‘deep breathing’ provided a big turbocharger and eliminates the breathlessness of engines fitted with a small turbocharger.
