No4 Posted December 25, 2003 Share Posted December 25, 2003 Thielert Diesel http://www.centurion-engines.com/index.htm The Thielert diesels are becoming quite popular. They are offered new in some Diamond aircraft, as a retro fit for pipers and cessnas, and will be available for homebuilts. They come in two sizes, 1.7 135hp 4 cylinder water cooled turbocharged 135 kg complete with reduction drive and constant speed propeller drive $19,500 4.0 310hp V8 twin turbocharged 285 kg with psru and csu $48,000 The engines are certified conversions of Mercedes Benz auto diesels. They run on any mix of jet fuel and diesel. In identical aircraft an IO-360 uses 9.5 gph, whilst the thielert uses 5 gph. The range increased from 570nm to 750 nm. Speeds are the same at 130 knots. The lack of total horsepower in the 1.7 is apparently made up for by the high torque throughout the rev range, which leads to a similar horspower at cruise rpm in respect to the lyc. The V8 is due to be standard in the Gippsland Airvan, a plane similar to a Cessna 206 I used to dream about Mercedes making a V8 aero diesel, and now it's come true! I believe these engines are the future; efficient, low cost fuel, greatly reduced fire hazard, no ignition, probably very reliable. Still pretty keen on the V10 Volkswagen (400hp)and Volvo 5 cylinder(230hp) aswell. Quote The Coconut King Link to comment Share on other sites More sharing options...
