smallfiatlogo.jpgFiat Powertrain Technologies has unveiled the latest revision of it’s 1.9 litre JTD MultiJet 16 valve inline-4 turbodiesel engine, which uses twin stage turbocharging to produce high power and massive torque in a wide RPM range at the same time.

Low end torque has improved by 50% over current JTD MultiJet models, with 300Nm available from just 1,250rpm going up to peak torque of 400Nm at 2,000rpm. The new engine is available in two stages of tune – 177 horsepower and 188 horsepower at 4,000rpm. The higher 188 horses version is exclusively for Fiat and Fiat Group companies like Alfa Romeo and Lancia, while the 177 horsepower version will be made available for purchase to customers. Nanjing as one of the first customers comes to mind – they were reported to be sourcing a powerful turbodiesel for it’s MG 7 sedan from an European manufacturer.

The new engine uses a 16.5 compression ratio, low-voltage metallic glow plugs, an improved EGR cooler, and a new inlet port design. It complies with projected Euro 5 emission standards. It has a cast iron block and an aluminium alloy head.

The 177hp version will be available in July 2007 onwards, while the 188hp version is set to be launched in June 2008. The engines will be produced at Pratola Serra in Italy.
