Emission from mobile sources causes human and environment exposure to hazardous, toxic substances. Because of civilization diseases expansion it is very important to estimate a toxic influence of emitted by combustion engine substances on human health. This paper presents the results of analysis of platinum-rhodium active coating application in diesel engine on toxicity of volatile organic compounds (VOC’s) in exhaust gases.. The catalyst was applied on SB.3.1 compression ignition engine valves surface. A special methodology of engine exhaust toxicity was applied: calculation of Toxic Equivalent Factor (TEF). For estimation of volatile organic compounds toxicity in the engine exhaust gases as a indicator benzene was chosen. The calculation of TEFs was base don Recommended Maximum Concentration Limits (RMCL), for one year period, according to polish Minister of Environment Directive (Dz.U.2003 nr 1 poz. 12). Toxicity Equivalent Factor was calculated for total volatile organic compounds identified in every chosen point of SB3.1 engine work and toxic. A comparison analysis of VOC’s toxicity in the engine exhausts in both conditions (with and without platinum rhodium active coating on the engine valve surface) was done. The analysis results show that inner catalyst application causes significant toxicity decrease for lower engine loads for both chosen rotational speeds.
