The most common JTD engine is the 1.9 L (1910 cc) straight-4 found on various brands and models.

In 1999 it was introduced with the Fiat Punto and Fiat Brava/Fiat Bravo/Fiat Marea. The engine block weighs approximately 125 kg (276 lb).
The Multijet second generation features a common-rail design and is available with five different power outputs. The 8-valve version has 100 PS (74 kW; 99 hp), 120 PS (88 kW; 120 hp) or 130 PS (96 kW; 130 hp), the last two with variable geometry turbocharger; and the 16-valve version has 150 PS (110 kW; 150 hp) or 170 PS (130 kW; 170 hp).
