Local GM engines in Chevies

[Genie47]

Firstly. Aveo.

 

The 1.4L ETECII engine is actually a GM Family I engine designed in the 1970s. Both the 1.4 DOHC and 1.5 SOHC are Family I engines. Family I engines are designed by Adam Opel. DOHC versions feature aluminium cylinder blocks.

 

Local Optra and Optra5 in the 1.6L DOHC variants are also Family I engines.

 

Only the Malaysian Optra LT1.8 is using a Family II engine.

 

ETECII is EuroIII compliant.

Does that means that the engines in our cars are 30+ technological years old!???

[Julian]

Don't worry... i think not only GM lah... other company should be doing it too since the concept is likely abt the same

[Cookiemonster]

Not really worried but kinda surprise that's all.

[Spango]

Does that mean that the engine can use those old S rated engine oil, since it is 70s technology?

 

BTW, is EuroIII a very old standard, since a 1970 engine can also meet it?

[Genie47]

There is a big difference between design and technology. True the Family series of engines are designed in the 70s but the technology is present. BTW, ETECII's predecessor is DTEC which is a Family II engine. Ecotec 1.6 and 1.8 from Opel are Family II. Twinport which is found in the current Opel Astra is also Family II. The main Family I engines now in use are in the GMDAT Chevies. If your Chevy is less than 1.4L as in 1.1 and 1.2L, it is Family 0. The older Astra's as in the SAF Astra wagons are Family I ditto for the 1.6L versions. Only the 1.8 and above Astras are Family II but if it is 1.6L and Eotec, it is Family II. Calibra and Vectra are Family II powered.

EuroIII came into being in 1997-1998. Is being superceded by EuroIV this year.

Wow!

thks for the detailed explaination Genie!

How you knew so much?

 

But I should say that our Aveo does have one of the best 1.4 engine around. Right, Genie?

[Genie47]

The French have the better 1.4L around.

[Cookiemonster]

Still not too bad.

Ours ain't the worst.

so that does mean good or bad for our local Aveo and Optra?

[Spango]

It means we are driving a 1970s car... Groovy!

No, I think what he meant was the technology started in the 70's, but it the current is an improved ones which meet today's euro standard. Alot of today's engine technology can be traced back as far as the 60's or earlier..eg. Mazda rotary engine, boxer, V8, etc. But those you see in modern cars are the latest version. Other gadget's technology like broquet, prozone, etc.. was used in WW2.
