Nord is italian for north. In this case I think the term refers to the inline 4 cylinder engine made near Milano. (Which is different to the horizontally opposed 4 cylinder 'boxer' engine used in the Alfasud...built in the south/sud - Napoli).

alfetta is correct. Nord is just shorthand for the inline DOHC 4 cylinder.

Is a twinspark 75 engine considered a NORD engine

alfetta is correct. Nord is just shorthand for the inline DOHC 4 cylinder.
Interesting question asked by Alfanaut! Let's dig a little deeper. From what moment was the inline DOHC 4 cylinder called NORD? And where did it stop?

I would think it concerns petrol engines only and started from the moment that the full aluminium (block and head) version came in existence in 1955. In my opinion it concerns engines that were dropped in the following series of cars:
- the '750' series Giulietta 1300 cc
- the '101' series Giulietta 1300 cc
- the '105' and '115' Giulia range 1300, 1600, 1750 and 2000cc
- the '116' Alfetta and Giulietta range 1300, 1600, 1750/1800 and 2000cc
- the '162' Alfa 75 and 90 series 1600, 1750/1800, 2000cc

Is the 'Twin Spark' inline DOHC 4 cylinder '162' in the Alfa 75 a NORD engine or is it in a league of it's own? What about the 'Twin Spark' engines in the early Alfa 155 before they dropped in the Lancia/Fiat engines?

Ciao, Olaf

Wasn't the Nord name (Milan) intended to distinguish the traditional inline four engine from the Sud flat four engine (Naples)?

I think the name arose when "Milano" disappeared from the Alfa badge. Same time the Alfasud was introduced. This was a political issue in Italy in the early 70's. Fiat merged with Alfa, then went into bankruptcy; the government took over. Alfa was developing a new car (became the "Sud"), and the gov't decided to open the new factory in the south where unemployment was pushing 20%. Alfa dropped the "Milano" label at the bottom of the badge.

FIAT had nothing to do with it at that time. Alfa Romeo was effectively taken over by the Italian government - by IRI in 1933 to faciliatate Mussolini's interests and continued to be run by IRI until 1980. In the early 70's the Alfasud factory came online and the Milano was dropped off the badge. In 1980 Alfa was taken over by the government holding company Finmeccanica. FIAT didn't buy Alfa Romeo until 1986.

Nord, as referred to above refers to the 4-cylinder engine that traces its design to the early Giulietta engine first built at Portello and then later in Arese - it was used to differerntiate the design from the Sud boxer engine.

Olaf, I hope you don't mind me editing your post!!!!

At least in the UK, my understanding is the following are regarded as Nord engines:

- the full aluminium (block and head) fitted to the following series of cars:
- the '750' series Giulietta 1300 cc
- the '101' series Giulietta 1300 cc
- the '105' and '115' Giulia range 1300, 1600, 1750 and 2000cc
- the '116' Alfetta and Giulietta range 1300, 1600, 1750/1800 and 2000cc

- the '162' Alfa 75 and 90 series 1600, 1750/1800, 2000cc which is a a 'Twin Spark' inline DOHC 4 cylinder '162' is commonly referred to as the 'Twin Spark' engines as are those of the Alfa 155 and 156, etc.

Ciao, Olaf
PS the Twinspark fitted to the Guilia GTA and GTAJ from the 1960s and 1970s is a Nord engine.

PPS The Alfasud factory (Sud = South to distinguish it from the Alfettas produced in the Milan in the North) was opened around 1972 to produce the Alfasud with the flat four engine (AKA "Boxer" engine) designed mostly by Rudolf Hrushka, an Austrian automotive engineer who had previously worked for Porche (as did Carlo Abarth who was also Austrian) who, co-incidentally, are famous for their 4 and subsequently 6 cylinder engines.

Another useless fact is that Hrushka was also involved in some elements of the design of the Tiger 1 tank during WW2.

add:
"designed by the genius Giuseppe Busso" who also designed the glorious V6 hence the slogan "Busso or Bust!"

I believe Busso was also responsible for the first Alfa Romeo alloy DOHC 4 in-line in the 1900 yet that engine is generally not referred to as a "Nord" yet it shares most of its configuration with the Nord.

The number of plugs per cylinder is not really something to go by as both the GTA and the TwinSpark had the double plug configuration but are both Nord engines.

BTW, the Nord was also featured in the 164 (TS) and the Alfa 75 Turbo.

Olaf,

the GTA-SA is incorrect - it is shown incorrectly in Fusi and a whole bunch of other publications - it is the same as the regular 1600 GTA. The bore and stroke dimensions given are for the short stroke GTA 1600F2 engine w/ monobloc.

Correction made!

Olaf,

the GTA-SA is incorrect - it is shown incorrectly in Fusi and a whole bunch of other publications - it is the same as the regular 1600 GTA. The bore and stroke dimensions given are for the short stroke GTA 1600F2 engine w/ monobloc.
Hello Alleggerita,

Correction made! Thanks for the input. Do you know of more versions?

and Hello Rafael,

Thanks for the list!

Ciao, Olaf

As most have stated, Nord engine became the moniker for the in line 4 cyl all alloy (aluninium alloy) engine of Alfa models build in Milano. Sud engine build near Napoli for the Alfasud, 33s and Arna (with a Nissan Cherry body). The designer of the Sud, Rudolph Haska, was involded in the development of the KDF wager (VW type 1) while with Porsche in the '30/'40s.
One stated, that the 1900 and later 2000 version was all alloy. The engine block of those were cast ion, cyl. head alloy - all though sinilar in configuration to the "Nord" engines, it was physically a bigger engine. It ended in Brazil in the old 2000 Berlina with 2350 cc.
Nord engines was build from 1954 (giulietta) as 1290 cc, last versions was a 1995 cc (84mm bore, 90 mm stoke) 1773 cc (84x80) and 1749 cc(83,4x80) of the 155 2,0, 1,8 and 1,7 TS. Last model with Nord engines was 164 2,0 TS (1962 cc, 84x88,5) in 1997. The engine block is higher in the 1600 (25 mm), 1750 and 2000 (40 mm).
The Nord (and Sud/33 engine plus 2 Fiat engines) was replaced from 1995 on by the new Fiat Group Modulo engine family, cast ion block, alu head, 4 valve per cylinder (except some Fiat 1,4s with 3 valves and diesels with 2) and 4 or 5 cylinders petrol and diesels. Lastest version of this is a 1750 cc (ring any bells?) TB (turbo benzina) with 200 HP in the 159/Brera GTV/Spider. The Alfa version of the Modulo engines have a cyl head design with holes for either 2 spark plugs or 1 plug and injection nozzle per cyl.
