News, facts, and comments on the coming revolution for piston-engine aircraft.
In 1998, one diesel engine flew on a converted airplane for the first time since 1945. Today, close to 4,000 singles and twins are flying. This is the beginning of a worldwide trend which will eventually allow a rebirth of the piston-engined aircraft, around new specs and new missions.

The Beech Duke Thielert conversion shows what a breakthrough diesel can make
Germany: The Beech Duke with Thielert V8 350HP has flown for the first time on November 18. This is the first diesel conversion that demonstrates a reduced weight compared with original gasoline engines: Exactly 50 Lbs. The Duke diesel is faster by 10 Knots at FL 220 despite a slightly lower power at sea level. Here is comparative performance figures claimed by Martin Hagensieker, see http://www.dukeb60.de/ with photographs:
Power_________350 hp_____________________380 hp
Cruisepower______70 %_______________________67 %
Fuelflow/h______2 x 45 ltr./11 gal._____________2 x 80 ltr./20 gal.
Fuel capacity_______78 ltr./232 gal.__________878 ltr. 232 gal.
Fuel___________Jet-Fuel__________________AVGAS 100 LL
Fuelprice Europe___65 – 1,45 EUR/ltr._________1,45 – 1,80 EUR/ltr.
Fuelprice USA____3 – 4 USD/gal._____________4 – 5 USD/gal.
Speed________220 kts/FL 220______________210 kts./FL 220
Climbspeed______1,200 ft/min________________1,000 ft/min
TBO__________2,400 hour__________________1,600 hour
for Overhaul___2 x 50.000 EUR____________2 x 60.000 EUR
for first kit___2 x 175.000 EUR__________N/A
Range___________2.000 nm_________________1.100 nm
Note that with a range of 2,000NM, the Duke Thielert can fly from any destination in Western Europe to any destination on the East coast of North America both ways in three legs, with required reserves on the Atlantic. And, at the (low) market price of a Beech Duke today, plus some $ 400,000 conversion cost, and a fuel flow of 22 gallons/hour of Jetfuel, it will be the most affordable business aircraft for such a mission.

Every month: news, facts, and comments on the coming revolution for piston-engines aircrafts between 130 and 400 HP: Retrofitting a diesel engine to run on Jetfuel or Kerosene, reduce Gallons/Hour by some 30%, eliminate ignition systems (magnetos, spark plugs) and their problems, eliminate mixture control, increase TBO to 2,400-3,000 hours, increase performance between 6,000 and 12,500 ft., and drastically reduce Operating Costs.
The letter is intended for piston engines aircraft owners, manufacturers, fleet operators and FBOs, re-manufacturers of engines for these aircrafts, manufacturers of engine components and ancillaries, and all professionals acting in decisions of engine exchange or refitting at TBO, in North and South America, Pacific Rim, African continent, and all parts of the world were Avgas, Mogas, Kerosene and Jetfuel are available.
