RAF Cosford

Went to the bikemeet at cosford today. Fantastic museum, free & full of planes bombs & engines etc. The interesting thing for me was the Junkers engine 6cyl 12 piston 2crankshaft 600hp 16.62liter 2stoke diesel 1938.

And there was me thinking that aero-diesel's were a new concept! Had an email from an Aussie who was into 2 stroke diesels some years back. It's hard to imagine an engine with a more violent internal process. Bet the sound is pretty loud as well

Interestingly diesel combustion is perfectly suited to the 2 stroke process. It always surprised me it was never employed in car engines - I'm aware some manufacturers looked into it but it never made production. Sadly as far as biking is concerned it requires what is in effect a large supercharger and so not so practical. Not the kind of thing you want your scarf being sucked in to then again, I guess you could say that about the back wheel as well!

Yeah nothing like a two-stroke diesel. An Aussie is having a go at structuring an engine using the Junker principle http://www.billzilla.org/ideas4.htm Then there is Diesel Air in the UK which has already developed a two-stroke diesel http://www.dair.co.uk/

Now that has to be something, I'm looking at this 2 cylinder engine thinking - MMMMM! Now if you make a smaller version and slot that into a bike, or even a car with high gearing to suit you'd have a powerful unit.

I still love the sweet sound of them V configured GM two stroke diesels, music to my ears, but maybe noise to others !

A friend of mine worked for the company that was putting the Diesel Air engine into an airship. They got their engines as components they had to assemble. It took a fair bit of work to get it to run reliably. The airship company went bust.

I went to Weslake for a business meeting a few years ago and saw one of the diesel air engines sat on a bench when we had a tour of their workshops. Neat, small little unit.

As an aside Ludwig Elsbett (of Elsbett veg oil engine fame) worked for Junkers in development during WWII working on their 2 stroke engine.
