In “Motor” No. 29 of July 21, 2001– Alfa Romeo 147 test with a diesel motor. Today, the “end of the world” discussed in the initial title of the post is related to, to name a few, the departure of diesel. At that time, it was an unpleasant reflection on the intro of a diesel system in the Alfa 147 engine variety. As it ended up, nevertheless, the result of this “unclean” was not so bad …
How is Alfa Romeo? The majority of us will address: red, quick, loud, tough and strong. It is likewise not excellent and untidy, however it is inadequately completed.
The Italians worked for years to develop such a picture of their items. And now they turn whatever upside down.
When the Alfa Romeo 147 was called Car of the Year 2001, it was just readily available in a three-door variation, with fuel engines just.
But this ought to likewise be a vehicle that, as befits Alfa, wishes to be worthy of the name of a cars. Now, nevertheless, it is likewise used with 5 doors and a diesel motor.
The interior of the JTD variation does not vary much from what is understood from the gas variations, just the tachometer has a smaller sized variety to be utilized. It has a great radio, air conditioning unit and lots of other facilities.
In the brand-new variation of the rear door manage, as in the big Alfa 156, thankfully concealed in the pillars– it might not be really comfy, however it permitted to preserve the aggressive, stylish design of the cars and truck.
But the lazy diesel in Alfa Romeo? Perhaps this is some type of misconception? Specifically for individuals who have actually had close contact with the 1910 cc JTD 4 cylinder. 3
This universal diesel motor from the Fiat issue has direct injection of the common rail system (in Italian it is called Unijet), an eight-valve cylinder head, turbocharging and air subcooling … and other criteria in the classification all formerly understood. In Fiat Bravo/ Brava 101 KM and 200 Nm, in Marei and Multipli 110 KM and 200 Nm, in Punto 80 KM and 196 Nm, in Alfa 156 105 KM and 225 Nm, and in “147” … 110 KM and 275 Nm. Each time with a practically similar optimum pressure of about 1 bar. Where do these distinctions come from? Well, it originates from using various turbochargers and various injection control programs.
Recently and, as it ends up, the very best variation of the 1.9 JTD system has actually struck the Alfa147 It utilizes a turbocharger with a variable geometry of turbine blades. This did not a lot lead to a remarkably high power worth as a considerable boost in torque. The outcome is that the 147 JTD speeds up much better than the 120 HP, is nearly 100 kg lighter than the 1.6 gas, and has practically the exact same leading speed.

In useful usage, you require to get utilized to the engine with a little turbo. The response to pushing the accelerator pedal at low revs is not instant– the turbine needs to have time to increase pressure in numerous inlet passages, and too mild a start can result in stalling of the engine.
But these are split seconds, and after that, in each equipment in the variety from 2,000 to 4,000 rpm, the vehicle gets an unique “kick” and velocity, as befits a cars and truck called Alfa Romeo. The splendor is that it does so without unneeded sound, and the “low-speed” purring habits of the diesel enables you to listen to the radio with no problems, even at high speeds.
The JTD engine is covered by a soundproof cover, so you can’t see all the devices around it. It’s not tough to think it’s a diesel by the noise, it’s not excessively loud.
The 2nd essential thing– the designers dealt with a little kind of essential transformation of modern-day turbodiesels. The engine might be “turned”, albeit with less effectiveness, as much as around 5,000 rpm and, as an outcome, there was no requirement for a six-speed transmission.
So we have Alpha alive and it’s no surprise. What about fuel usage? The average from our test was 6.4 dm 3/ 100 km, it promotes itself. Affordable, contemporary engine and aerodynamic body do their task. This Alfa is not greedy!
The Alfa 147 JTD makes a striking look under the radiator. Our typical fuel usage of 6.4 dm3/ 100 km did not enable us to drive 1000 km without refueling, however it was close: the tank has a capability of 60 dm3.
Here’s the evidence– typical and immediate fuel usage can be continuously kept track of on the big on-board computer system display screen. The latter often reaches a lots approximately dm 3/ 100 km, however these are really brief.
Perhaps not extremely well and strongly suspended? Another surprise here. We do not understand if the JTD variation had “softer” shock absorbers, however our test automobile overperformed in this regard. He passed through holes and manholes completely, it was even worse on the long, undulating disproportion of the roadway. There was even rubbing of the lower plastic engine cover versus the asphalt on an apparently smooth roadway, and the extreme softness of the front suspension triggered the rubber strap under the front bumper to break. Could not the contractor have thought about the increased weight of the engine?
On the other hand, a premium vehicle suspension does not need intricate changes to keep the automobile running efficiently. There is no objection in this regard. Perhaps it’s Polish roadways that do not enable 100% chassis upgrades.
Our readers currently understand that the Alfa 147 is well geared up, ergonomically improved and completely completed. It would not have actually won the Car of the Year title otherwise. As an outcome, lots of old viewpoints about the individuality of cars of this brand name requirement verification. Even– it ends up– the color red, although readily available, does not control the series of the 147 design. Is this silver, cost-effective, soft suspension and comfy automobile an Alfa Romeo?
