In the paper, the authors made an analysis of mechanisms of the toxic components formation of exhaust gases in the direct injection engines. The genesis as well as the typical engine construction solution with the use of direct injection in diesel engines and these with positive ignition was developed. The typical construction solution of the Common Rail (CR) system, which is one of many elements increasing the purity of exhaust gases, was also presented. The basic advantages of direct injection, especially in case of the positive ignition engine, were also briefly described. Then, the mechanism for the formation of toxic components of exhaust gases in the direct injection diesel engines was presented. Moreover, the definition and dependency on the indicated mean effective pressure were shown, and the closed indicator graph, which is indispensable to calculate values of this pressure, was also (graphically) presented. In this paper, the mechanisms and processes, with the use of which it is possible to reduce the emission of toxic components of exhaust gases, were quoted. The exhaust gas recirculation with the EGR valve, which allows supplying the exact amount of gases to the engine inlet system, is such an example. The advantages of using this type of solutions were described, and a typical construction solution was presented in the diagram. The paper was completed with a conclusion, which emphasised the importance of direct injection on reducing the emission of toxic components of exhaust gases.
