In paper the impact of intentionally chlorine-contaminated fuel on nitrogen oxides emission control elements in compression engine was described. The quality of fuel used is of key importance for the failure-free operation of the engine. Fuel contamination can occur mainly at the transport or storage stage.The main attention was paid to the EGR heat exchanger, which is used for exhaust gases recirculation, being one of the ways to reduce the emission of harmful NOx. The tests were conducted under laboratory conditions (research engine stand tests) in cycles consisting of four phases. The fuel used was intentionally contaminated with chlorine. The test was interrupted after 250 hours at the engine failure and deposits appearance at the EGR heat exchanger. Test results of chemical composition of deposits, analytical methods used and sources and the cause of deposits appearance were described in present paper.
