Study of the Car Fifth Tdi-pcr-2l Diesel Engine with Selective Catalytic Reduction Medial Load

Author is pointing at the possibility of the utilisation of simulated computations for the research and development of the Car TDI diesel engines. Modern technical potential of them is discussed in the opening part of the paper with emphasis on the Latest Fuel Injection Technology. In this part of the paper one can find a short characteristics of the Engine, Exhaust Gas Recirculation, Selective Catalytic Reduction, MOPS Program and them before made Verification of the simulated results as real parameters. The main part contains Computations with special point of view on the influence of modern TDI engine variable configuration and setting with Piezo Common Rail Injection System (PCR) on economic and ecological property in one-point test in medial load of the car TDI Diesel engine FIFTH PCR 2L, dedicated to era of the relevance Euro 5 (20082020). In the paper it is getting on methodological solution demonstration of Diesel Dilemma at standard apply of EGR Technology for NOx diminution with typical BSFC increase. New SCR Technology, known from large scale to Heavy Duty Tracks, is in this paper tested versus EGR. Computation and analysis results with SCRT show excellent low NOx and too BSFC and PM. For emissions amelioration with SCRT any compromises do not have to done in next time. The main simulation result is: NOx reduction efficiency of 96.5-97 %! SCRT by exploitation all the time diminish BSFC by 10-20 % and the best result is NOx, PM, CHx, CO and exhaust noise diminution in atmosphere. In principle, it can be regarded that actual Dilemma of modern Diesel engines as very well resolved. Here presented results of Car Diesel engine TDI FIFTH 2L PCR are very comparable with real results operating with urea-SCR in large scale to Heavy Duty Tracks. It warrants us to apply practice know-how and practice realisation from HD tracks to Car diesel engines. At the end of the paper there is short substantiation of SCR profitability. It is really to say from global point of view that diesel engines have such potential which guarantees their successful development during the next thirty-year of the 21st century. The utilization of the computer simulation is certainly a means for acceleration of the R&D work and for reduction of costs in permanent innovation of TDI-Diesel engines.
