PSA Peugeot Citroën to Develop New 1-Liter Engine Family

PSA Peugeot Citroën plans to develop a new family of 1-litre 3-cylinder gasoline engines with power ranging from 70 to 100 hp (52 to 75 kW). The company plans to use the new engines to bring to market vehicles with CO2 emissions below 100 g/km without additional technology.

Two manufacturing sites will be established, one in France, the other in Eastern Europe.

The first facility, with an annual capacity of 600,000 engines, will be located in France on the PSA Peugeot Citroën site at Trémery and will be operational as of 2011. In 2007, the Trémery plant, located 15 km from Metz, manufactured 1.74 million engines. Since being set up in 1979, the plant has produced more than 30 million engines.

A second facility will be established in Eastern Europe by 2012. In order to find the best location for this additional engine-making plant, PSA Peugeot Citroën has begun looking at several countries in this region. The choice will be made in mid-2008.

to get 100hp/litre, they will need to use turbocharging and direct injection, no?

mahonj

I guess they must have liked what they found in the C1/Aygo/107 collaboration.
I hope they can contain the NVH.

I guess this is the easiest way to build very low CO2 cars without hybridization or diesel (both too expensive for small cars).

It would seem that smaller displacement high output engines are the way to go to reduce CO2. They did not say it, but the 100 hp model would probably be a turbo. The GM 1l 3 cylinder in the Volt is 70 hp with a turbo, so this might be DI as well. The cost of DI and turbo would be a factor, but still might come under the cost for full hybrid.

My guess is that any new engines developed will have to be direct injection. Specifically, vertical injection in the center of the cylinder - technical term spray-guided direct injection. This should allow for best efficiency and cleanest emissions. I figured about 25 years ago that such di, with compression of 12 - 13:1, should yield between 90 - 110 hp/liter without turbo and approx. 40 - 60% more with turbo or super charger. Actually, you get a volumetric efficiency increase from about 35% to 45%, about where diesel engines were back then. Of course, diesels have pushed higher since then, too.
When Mercedes introduced the 1,8l, I4, tubo DiesOtto last year, I thought they were getting very close. That engine, I believe was rated at somewhere around 180 hp and can probably be tweaked still higher.

This is one more sign for the decay of the european car industry. in two years time, little full electric cars from mitsubishi, subaru and half a dozen chinese , will turn the industry like the internet did to many companies in the ninties.

note that the honda civic si delivered 200hp from a 2l naturally aspirated engine. this is completely do-able with only VVT and smart engine management.

Hybrid vehicles as well as full EVs will be out in 3-4 years in Europe. These include the Renault Megane (Project Better Place), Mitsubishi MiEV, the Fiat 500 hybrid, the Pininfarina-Bollore EV, the Th!nk, and so on...
The Fiat hybrid is based on a 900cc SGE out this year, and Peugeot are doing the right thing in also designing a more efficient and downsized engine....

How, pray tell, can this be seen as a decline? Surely this is something of a Renaissance, and of the rosiest kind!

GdB

What he meant was a decline of the wasteful automotive designs of the past.

For a change, we will actually get a decent choice of high efficiency designs.

And of course if you want to waste your money burning fuel, just buy a used obsolete piece of junk.

Now all we need is more fuel tax instead of other tax to speed the transition.

SJC

If you look at American auto history you see huge cars with chrome bumpers and all manner of things that make no sense now. I am old enough to remember when seat belts were optional equipment that no one ordered and if they were in the car, people sat on them. The car industry has come a long way in fits and starts. This is yet another wave of change for the better as far as I can see.
