Abstract
One of the methods of improving the operating parameters of internal combustion engines is increasing the oxygen content in the air supplied to the combustion chamber by supplying ozone to the intake system or to the working space of the engine. It is advantageous to make the surface of the engine intake system in a rough or ribbed form. This causes turbulence in the supplied air with ozone, which may increase the efficiency of ozone in contact with the fuel in the combustion chamber. The article presents the results of tests carried out on dynamometric stands with compression-ignition engines. The test object was the FIAT 1.3 JTD MULTIJET engine. The main aim of this work is to determine the effect of ozone on engine operating parameters and the toxicity of exhaust gases. In particular test cycles the ozone was fed into the suction manifold and, along with the sucked air, fed to the combustion chamber. The test results include power and torque measurements for 100%, 50% and 10% of the maximum engine load.
