MAPPING OPTIMIZATION FOR COMMON RAIL DIESEL CONVERSIONS FROM THE AUTOMOTIVE TO THE FLYING APPLICATIONS

Performance of electronic controlled diesel engine is depended on quality of the map(s). In this paper, the implementation of an electronic-control map in common rail diesel engine is made, the character of operational profile in diesel engine and rule of typical profile data obtained from experiment is analyzed, a method of developing these surfaces from very few data point is applied. The particular application of aircraft and elicopter common rail direct injection diesel engines is considered. The steps of this experimental optimization activity is presented in order to test to operational profile demand. This demand is very different from the automotive to the aircraft/helicopter application. The preparation of the test engine(s) and of the test electronics for brake tests is completely different. Also the mapping technique differs substantially being the primary objectives widely different.
