Convert from Avgas to Jet-A Lindbergh Foundation Winner.
LINDBERGH FOUNDATION GRANT GOES TO ENGINE INNOVATOR (http://www.avweb.com/eletter/archive...ll.html#195734) Pilots of older aircraft worry about the future availability of 100LL avgas, and environmentalists are not happy with the ecological impact of leaded fuel. To satisfy both concerns, inventor Tom Ehresman of Colorado is working on an engine modification that would allow avgas-burning engines to convert to diesel or Jet-A. That is just the kind of innovation the Lindbergh Foundation seeks to support -- new aviation technology that preserves the health of our natural environment. The grant of $10,580 reflects the amount that Charles Lindbergh spent to build the Spirit of St. Louis. Ehresman hopes the award will help to attract more investors, and if he has the financial support, he could have a working prototype in two or three years. The retrofit kit could go to market for about $6,000 or so, he estimated. http://www.avweb.com/eletter/archive...ll.html#195734 |

New planes use 100LL too. True. But the concept seems valid for piston aircraft. What bothers me, is the potential for additional strain on the engine when converted to diesel operation. |

As it should for anyone contemplating doing it. Wasn't it GM a couple of decades back that had the big fiasco of blown engines when they tried to convert their existing gas engines to diesel? -- Jim Pennino Remove .spam.sux to reply. |

Jim, Yeah, GM's very first line of passenger car diesels were merely converted small block Chevys. It didn't work so well. But, I would hope that in the ensuing decades some new technologies have developed which might make this a more feasable option. AFAIK the only way to make a reliable diesel engine is to design it to take the stress of a diesel from the start and gas engines aren't. -- Jim Pennino Remove .spam.sux to reply. |

The Olds 350. To the best of my knowledge, *every* auto manufacturer that tried a simple gas to diesel conversion failed the first iteration and ****ed off a bunch of customers. My own personal experience centered around the VW Rabbit diesel. In all fairness, both Olds and VW both got it right after a couple of years. Yeah, after redesigning the engines as diesels. The experience has been that everyone that tries to convert a gas engine to diesel winds up with a blown engine. If you start with a diesel design you have a working engine. -- Jim Pennino Remove .spam.sux to reply. |

Maybe it's simply about preheating the fuel and retarding the spark. People keep saying our engines are "just tractor engines." Don |

The problem is gas engines go bang and diesel engines go BANG!!!. This puts greater stress on the engine parts which isn't a problem if you designed for that stress level in the first place. -- Jim Pennino Remove .spam.sux to reply. |
