MODELING OF 8-MODE TEST PROCEDURE FOR ZETOR FORTERRA 8641 TRACTOR

The paper describes the modeling of 8-mode NRSC test procedure based on previously measured characteristics of carbon monoxide (CO), carbon dioxide (CO2), hydrocarbons (HC), nitrogen oxides (NOx) and particulates (PM). It makes possible to compare the current technical condition of an internal combustion engine of an agricultural tractor with the requirements of the certification test. Based on measured characteristics, it is also possible to model any other cycle without further measurements (NRTC test procedure, cycle for specific conditions – mountain tractor, etc.). Detection of the degradation of technical condition of the tractor and its early maintenance can help to improve the environment by reducing production of harmful substances emitted into the air and save money while reducing fuel consumption
