Aloitan uuden ketjun aiheesta, kun ei viitsi tukkia juttua väärien otsikoiden alle. Eli tuosta uudesta Fiat tehdaiden tuotteesta juttua. Mitä enemmän siitä lukee kommenteja sitä hienommalta paketilta se kuulostaa.
1000rpm paikkeilta lähtee vääntökäyrä aikalailla jyrkkään nousuun ja 300Nm ylittyy jo 1250rpm kohdalla Kuulostaa aika hurjalta. Eihän siinä olla vielä kunnolla tyhjäkäynniltä poistuttu!
Vois tosiaan kuvitella, että varsinkin automaatin kaverina mahtaa olla hieno ajettava tuo paketti. Jo TiDS A on kerännyt melkoisen määrän positiivisia kommentteja. Uuteen kun on tulossa uudistettu versio myös vaihteistosta. Liekö pelkkä softa uudistus, mutta nimetty Sport Shift Sentronic.
edit: Hinnoittelusta. TTiD maksaa 3500€ enemmän kuin 150hp TidS moottori, tai vastaavasti 3050€ enemmän kuin 2.0T versio, ja jopa 1550€ enemmän kuin 2.8v6t. Eli moottori on kaikkein kallein tällähetkellä tarjolla oleva vaihtoehto 9-3 malleihin. Jopa 11655€ enemmän kuin 1.8i !
Jotain netistä löytynyttä:
Ja lisää speksejä: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 JTD 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 thermo-structural 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.
With TST we have a small turbocharger operating at low rpm for optimal low-end-torque and response from low vehicle speed. This small turbo is passed when the required power output increases and a second turbocharger with higher size comes into operation. Besides the improvement of overall performances, the TST technology allows increasing the EGR rate without penalties on fuel consumption and therefore gives a relevant contribution towards NOx emission reduction.
The engine has been designed to comply with Euro 5 emission standards. This target has been achieved thanks to: reduction of the CR from 17.5 to 16.5 and adoption of low-voltage metallic glow plugs improved EGR cooler (with by-pass) and EGR valve adoption on Lambda sensor with DPF new design of inlet ducts.
As far as start of production, the 180 HP version is forecast in July this year; the 190 HP version is forecast in June 2008.
