News, facts, and comments on the coming revolution for piston-engine aircraft. News of December 10, 2008 Introducing the CMD GF56 Diesel Engine for General Aviation CMD is an Italian firm active in design engineering services for the marine, automotive and general aviation applications of internal combustion engines using all fuels including diesel. See: www.cmdengine.com. It is also manufacturing parts and components, and the range of FNM marine diesel engines. Some engines are based on FIAT blocks and some other are the marine version of FIAT engines (e.g. FIAT 1.3 Multijet for marine applications). CMD developed two aero engines: the GF56 and the ULM 220. The ULM 220 is a 4-cylinder gasoline air-cooled engine of 2.2 liters and 106 kW developed for light aircraft (ULM and VLA). In 2000, CMD initiated design for an innovative aeronautical diesel engine. GF56 has been designed and developed by CMD in cooperation with major Italian universities, the National Research Center and the Italian Aerospace Research Center (CIRA). CMD started the certification process of GF56 on February 2008 CMD sending application in EASA for DOA and engine TC. The first Type Certificate Board Meeting with the selected EASA Team members has been held on May 15th, 2008. This meeting formally signed the starting point of the certification process. GF56 is now accomplishing the development tests in order to freeze the engine configuration for the prototypes dedicated to the certification tests, which will begin in 2009 within a new plant dedicated to the aviation programs. Flight tests will also be performed. The GF56 main natural market is retrofitting existing airplanes. Its engine mount is designed to be compatible with the attachment points of Cirrus aircraft. Main features are: 6 cylinders horizontally opposed. Direct drive-Bore x stroke 106x105mm-Total displacement 5.56 liter. Power 300 HP at 2400 rpm. Power-to-weight ratio of 1 kg/kW. 2-stroke Diesel uniflow cycle. Roots supercharging system with integrated wastegate valve. Liquid cooling. Capable of using automotive diesel fuel or Jet A1. Injection by high pressure Common Rail system. Low piston speed (reduced rpm speed). Low MAP (Mean Effective Pressure). Two camshafts (no long rods), timing with cascade gears. Modular cylinders enclosed in one integral rigid and light semi engine block allowing easy development of a series of engines from 2 to 8 cylinders. Cylinder barrels and cylinder heads form a unique integrated element called “cartridge”. Cartridges and crankcase are held together with studs. A high pressure injection pump is mounted at rear of the engine. It feeds the common rail that distributes the fuel to the electro-injectors located on each cylinder-head via steel fuel lines located on top of the engine.

Mission Statement

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.
