Jet-A engines are now commonly used in general aviation. High utilization operators, such as flight schools, aerial work companies and surveillance operators, have transitioned to Jet-A engines. They offer significant savings on fuel burn and maintenance costs and down time. Jet-A engines, by using the Diesel cycle, burn less fuel (30 to 40 % less when compared to AvGas engines). Furthermore, Jet-A, in most regions of the world, is significantly cheaper than AvGas. In addition to this, scheduled maintenance intervals are significantly reduced when using a jet fuel piston engine. This means more hours flying and less hours in the maintenance hangar.
Continental Aerospace Technologies™ is the undisputed leader in Jet-A piston engines.
Retrofit – The Firewall-Forward-Kit
At the end of the year 2003, Continental Motors Group took the opportunity to evaluate one year serial production of Centurion 1.7 kerosene piston engine, the predecessor of the CD-135. While shipments to OEM running well, Thielert has recognized some potential to improve the retrofit kits for existing aircraft. In 2003 Continental Motors Group shipped the retrofit engines as an assembly kit with 930 parts. The outcome of the experience with this method is that kits have been shipped completely "firewall forward" pre-assembled and checked since the beginning of 2004. This method is offering the following advantages:
1. Superior quality of the retrofit kits: Prior to delivery, Continental tests the entire engine system, electronics, cooling, heating and intercooler on own dynamometers. As a certified production organization, Continental Motors Group improves the quality of the assembly and testing of the retrofit kits
2. Shorter aircraft service times: Since the pre-assembled retrofit kit can be installed more quickly at Continental Motors Group distributors, it is possible to reduce the service time of our customers' aircraft.
First, the original engine is removed and the firewall completely exposed.
The new Diesel engine is delivered ready for installation, already on the engine mount.
The engine, electrical harnesses and accessories are installed.
The automatic constant speed propeller is bolted to the engine.
The engine cowlings are reinstalled.
During the installation, the fuel system is modified and new tank caps are installed. Special markings are set, to avoid any misfuelling possibility.
The aircraft is now ready for a ground run and the first flight test.
Selected airframe with a Garmin® G1000™ integrated avionics suite can also benefit from a Diesel retrofit. Call us for more information.
