According to some website-
One of the second-generation Multijet, multivalve turbo diesel engines, the new 1.6 Multijet has 4 cylinders in line, 16 valves, a displacement of 1598 cc with a bore of 79.5 mm and a stroke of 80.5 mm. Two different engines will be produced: the first with 105 bhp at 4000 rpm and torque of 290 Nm at 1500 rpm, the second with 120 bhp at 4000 rpm and torque of 300 Nm at 1500 rpm.
The engine is supercharged by an electronically-controlled fixed-geometry turbo compressor (for the 105 bhp version) or variable-geometry (for the 120 bhp), to enhance power output while providing very high torque even at low revs.
Compared to the well-known and very popular 1.9 Multijet 120 bhp, the 1.6 Multijet series represents an important step forward. There are improvements in terms of performance, comfort, emissions and running costs, and there are also considerable advantages: with the same power, torque is improved by almost 25% (1500 rpm) and consumption is reduced by 8% (measured on the NEDC cycle). The car is also noticeably more pleasurable to drive, mainly thanks to the torque available at low revs. These objectives have been achieved mainly thanks to the optimised combustion which exploits the potential of the new injectors to the full.
Another factor in the improved performance is the multi-injection system, with 1600 bar in the 1.6 Multijet (in both power versions). The injection adapts to the engine speed, thus optimising performance in terms of perceived power and driveability.
Power and torque at the top of its class
The 1.6 Multijet has outstanding torque output in absolute terms, all the more surprising if we consider the cylinder capacity: the torque of 290 Nm in the 1.6 105 bhp (no less than 300 Nm in the 1.6 120 bhp) makes this engine the top performer among engines with a cylinder capacity of 1.8 litres or less. If we consider the specific torque (divided by cylinder capacity), the 1.6 is the highest-performing engine in the category up to 200 bhp, with the sole exception of “super-sports” engines.
That’s not all. If we consider that the maximum torque is generated at just 1500 rpm, we can instantly see why the 1.6 Multijet is a revolution among modern diesel engines: none of its latest-generation counterparts can offer such high performance at such low revs. In short, the new 1.6 Multijet offers an exciting drive that is not easy to find anywhere else, as can be seen from the acceleration and pick-up values: compared to the excellent 1.9 120 bhp, the 1.6 120 bhp records the same acceleration value (0-100 kph in just 10.5 seconds), and more importantly the pick-up from 80-120 kph in 5th gear is almost 4 seconds less (over 1 second is gained in 6th gear).
Last but not least, the combination of the new injection system with the latest-generation turbos (fixed geometry on the 105 bhp and variable for the 120 bhp) rounds off a truly impressive technological set up. The new turbos use technical features and materials capable of supporting greater thermal and mechanical loads, enabling maximum performance together with total reliability.
