Abstract

The paper proposes to analyse experimentally the influence of using oxyhydrogen gas, resulting from a process of electrolysis produced on board the vehicle, in supercharged compression ignition engine. The experiment consists in the series of the constant load tests (the same position of the accelerator), on the chassis dynamometer, initially starting with conventional fuel (standard diesel oil) and in the second phase by introducing the oxyhydrogen through engine manifold of the vehicle, with different volume percentages. The experimental data reveal a positive influence of the added oxyhydrogen on opacity of the flue gas and an increase of the NOx concentration. The mechanical parameters of the engine just highlighted certain trends, resulting in definitely the favourable enriching influence of oxyhydrogen.
