Vauxhall Vectra 2.2 HCCI (Insignia...)

[nutron]

It's a very old article as well, the Insignia is unlikely to see this engine based on what I read about it's state of development.

11 engines are known at the moment, only 7 will be available at launch:

1.6 R4 1598 ccm 115 PS

1.6 Turbo R4 1598 ccm 180 PS

1.8 R4 1796 ccm 140 PS

2.0 Turbo R4 1998 ccm 200 PS

2.0 Turbo R4 1998 ccm 220 PS

2.8 V6 V6 2792 ccm 260 PS

2.0 CDTI R4 1991 ccm 110 PS

2.0 CDTI R4 1991 ccm 130 PS

2.0 CDTI R4 1991 ccm 160 PS

2.9 V6 CDTI V6 2935 ccm 250 PS

sounds a good engine to me ..and no worry of cam belt or chain failure as i belive from reports in the vx world this new lump has no cam shafts uses electric valves .....wonder how good there gonna be tho on a vauxhall after 20k only time will tell what new faults they can think up ....

I would hate to be the first to try this engine would scare me to death.The Direct injection petrol promised diesel economy and turned out to be a lemon.

Do you know if the 2.0 cdti is a different unit than the 1.9cdti or have they just bored it out.

Do you know if the 2.0 cdti is a different unit than the 1.9cdti or have they just bored it out.

I understood the new 2.0 diesels are based on the 1.9 cdti but bigger, new software and euro5 (however... 1991 cc is exactly the same as the VM-Motori engines from the Antara but they are euro4 and have lower hp with a terrible consumption)

It could be the fuel system and / or the calibration that has changed to get more power and better emissions.

Is it direct injection or port injection?

Quote from an article I read (not specifically about this engine, more HCCI in general):

The fundamental ingredients in the recipe are a combustion pressure sensor to tell the computer what happened during the prior stroke, variable valve timing, and gasoline direct injection.

[Ste]

Yes, real time cylinder pressure is a must for HCCI, with diesels it's fairly easy to get a sensor in the cylinder - ie combined glow plug / pressure sensor. Petrols would prob need another tapping in the head.

Nice. Will be interesting to see what the emissions are for these.
