info here too;
http://www.subaru.com.au/news/?newsid=12608

quote from the speech about it by Subaru at the Paris motor show;
As announced at the Geneva Motor Show last year, we are enhancing our Subaru boxer engine lineup, and I’m pleased to announce that the development of the world’s first horizontally opposed diesel engine, the Subaru Boxer Turbo Diesel is nearly complete.

The superb rotational balance of the horizontally-opposed engine allows low vibration because the pistons counteract each other to cancel it out. Moreover, with its firmly supported crankshaft, the crankcase construction is strong enough to resist huge combustion pressure. The horizontally-opposed engine’s character is proving an excellent match for a diesel engine.

Also, the adoption of a thin journal for the crankshaf and turbo charger placed under the cylinder block enhances all the advantages of the Boxer Engine, which are “Low center of gravity” ”Low vibration” ”High rigidity & compactness” This deliver diesel’s powerful torque from the engine to the wheels, and increases traction, making the Subaru Boxer Turbo Diesel yet another achievement of Subaru’s advanced technology.

Last but not least, the Subaru Boxer Turbo Diesel boasts lower CO2 emissions in consideration of the environment. I anticipate unveiling the Subaru Boxer Turbo Diesel engine next year at Geneva Motor Show.

Thank you for your attention.
Will make some interesting conversions in a few years time.

"development of the world’s first horizontally opposed engine"

Commer trucks in the 50s and 60s had a horizontally opposed diesel engine. Had no heads. 2 bores and 4 pistons, Pistons compressed towards each other operated by big rocker arms off one crank below. Only had 2 injectors. Were commonly called Commer "Knocker" engines.

Common Knockers were called that because two pistons shared a common cylinder, they came (knocked) together in the centre of cylinder and a combustion chamber was created by the space between the tops of the pistons. They were also a 2 stroke Deisel engine & had a sound all of their own

Of course, like all great engineering ideas, the Germans thought of it first in the 1930's. Here is a pic of a Junkers opposed piston deisel engine used in high altitude bombers. All the poms did was lay it on its side (lol)

I've driven a "new" Pug...I know what they are like. I just don't like diesels.....just the smell of the fuel makes me throw up (not kidding) Run it on cooking oil and i might be slightly interested......

I don't think you can compare the junkers and commer "knocker" engines with a Subaru or VW design, pistons may be in the same plane but that is about all.

You also comparing two stoke engines with four stroke
