Hi Cargo Cult
Just found another reference to diesel engines. Thielert Aircraft Engines from Germany have recently received JAR certification for a 110hp engine that runs on Jet A1 or derv. They have a 125hp and 300hp design also. The 125hp is said to burn 15 litres per hour of jet fuel compared with the equivalent avgas guzzling Lycoming which burns 33litres per hour both at 75% power. You probably know that jet fuel is about a quarter the price of avgas which is over £1 per litre at my airfield. Wish I had diesel
No web link sorry.
