Subaru is coming out with a diesel boxer style engine. I wonder what it
weighs? |

Diesel in a homebuilt?
At Team Tango we have a builder who is planning to install a Delta
Hawk In a Tango 2. He has been waiting for several years and will receive one of the first production engines when they begint to ship. This year, again, they say this fall (and this time its for real). I am not aware of any other diesels designed for airplanes that are actually in play these days, but I haven't kept up on SMA, Thielert. I have heard of financial problems at the companies. I would havae financial problems trying to pay for one. |

... Not that I plan to do this but I was wondering, if one was going to plan to install a diesel in a homebuilt, what diesel would one put in? Lou Your location is not obvious from your email. In most of the world, diesels are available in a wide variety. In the US, where fuel consumption is only estimated from total mass flow and emission content at the exhasut, the choices are currently quite limited, and I am really not very happy with any of the choices. The 2 liter VW (Passat) is an all iron engine, and about all I know is that it is about 100 pounds heavier than its gasoline stablemate--which is partially aluminum. There are also V6 diesels offered in the Mercedes E320 and the Jeep Liberty, but I know even less about them. There are probably others that I haven't seen, and Isuzu has said that they will be back in the diesel market when the regulations have stabilized. Personally, I really do like the diesel idea--so I plan to take a very close look if/when any of the lighter small diesels (such as the 2 liter Mercedes) become available here. Of course, there are a couple of avitaion diesels (Thielert being the most widely known) that will bolt right in--but you have to fly a lot to save the initial cost difference back in fuel. You can correctly surmise from the above, that I tend to think in terms of automotive conversion as soon as the disucssion drifts away from the smaller Lycoming and Continental engines--and thier clones.

There is an english 2- cylinder 2 stroke of ~100hp that is based on the Jumo engines. There are a couple of German companies, one with a couple of certified gear reduced diesels, and there is an experimental diesel based on the Mercedes smart engine. Also there is the new Subaru diesel, and the latest pump-dues engine from VW. Ford also has a tight little european TDI in the 1.5L range, but I don't know what the figures on it are. I believe Lycoming makes a TDI for military applications, (UAV's) )but I've not seen it offered commercially. In a nutshell, if you aren't going delta-hawk, you will be looking overseas since domestic diesel tech is about a decade behind the curve. Of all of them the Jumo style engine in the UK peaks my interest, but it's probably cost prohibitive. It has a lower parts count, and is based on technology that has worked in aviation since the 30's. The flip side is their aren't very many documented installations. The automotive TDI's have direct injection systems that are computer controlled. Essentially they reduce cylinder pressure by injecting several pulses per stroke to simulate a gasoline combustion cycle. This makes for a lighter engine, but you are dependent on common rail injection, computer controls and greater sensitivity to fuel contamination. ( I am speculating on the fuel contamination based on injector design) Switching to mechanical injection on these engines substantially derates them. I am futzing around with a design based loosely on the old Packard diesel with some modern features from other engines. At the moment is is just a few CAD sketches, and I doubt if it will ever become a reality. But I am convinced the Packard design coupled with turbo- normalizing and modern casting/machining technology would provide the lowest parts count, with the highest reliability. |

What about the Light Sport Aircraft from InDus (???). I think it's called a Thorpedo(???). Memory says they flew one into Sun N Fun with a British made diesel installed. They plan to market it outside the USA. Go to ByDanJohnson dot com, he usually has the latest LSA stuff on his site. |

Lou Elaborating on earlier replies: I know of two English designs, both aircraft-specific, both two-stroke: see www.wilksch.com or www.dair.co.uk Both are very rare, I never met one except on the maker's demo-planes. I suspect their pricing is a bit prohibitive. Also I seem to remember a third English design but have no details. A couple of car conversions are flying in France, see one at http://membres.lycos.fr/dieselis (in French only, regrettably) and another at http://gazaile2.nmr7.free.fr/ both seem to suffer from engine weight. In Germany, Thielert markets a heavily modified Mercedes diesel, but this aiming at bigger planes. This engine powers the DA-40 and DA-42, highly successful in Europe these days. And I once met a guy in Belgium who adapts Subaru petrol engines mainly for autogyro use, I hope for the day he sets to work on the Subaru diesel. |
