Thanks, that's most helpful.
You might know that the First World War (1914-18) was won, not by the usual stories, but because Henry Ricardo invented a steel tank and a two-stroke CI engine to power it (The Tank) which ended trench warfare instantly and allowed advances at last. Ricardo predicted, during his long life, everything that was needed to be known about Diesel Engines.
You might be familiar with a little company that goes by the name of Allison. They are fitting ultra-high speed flywheels (in vacuo) to buses' brakes. The power stored is about 50 hp. It's then used for acceleration. Guess who holds the licence: Ricardo. Still there.
But to the point, this thread was about Fuel injection control. We worked it out and posted it on Wordpress.com/malcolmcochran (?wordpress.com/malc9141). If you look, you might say, it could be improved - True, we know that now but it's simple and reliable as we have it.
As for general diesel bits, yes, I have heard of Deltahawk etc.
In a plane, weight is everything (well, nearly) and my idea (15+ years ago) was to use loop scavenging (you'll be familiar with that) to permit a less-tall engine. Ie better packaged, lighter, etc.
I was both flattered and disappointed to find that Toyota, no less, built an engine like ours in about 2006 and couldn't get the required torque. That is exactly our problem but we haven't quite given up. However, that "torque" is for a different site.
