EXPERIMENTAL ASPECTS OF HYDROGEN USE AT DIESEL ENGINE BY DIESEL GAS METHOD

ABSTRACT
Due to good combustion properties of hydrogen comparative to diesel fuel, it can be used at the automotive Diesel engine for improvement of the energy performance and for reduction of the pollutants emissions level. The use of small hydrogen quantities which can be produced on the vehicle board represents another advantage. The paper presents some comparative results of the experimental investigations carried on a truck Diesel engine of 10.34 L displacement fuelled with diesel fuel and hydrogen at engine middle loads. The hydrogen was injected in the engine intake manifold at different volume flow rates from 9 L/min to 40 L/min. The general objective of the research is the analysis of the effects of the hydrogen use at the Diesel engines on the energy performance and on the pollutant emissions. The engine energy performance, pollutant emissions level and combustion parameters at the hydrogen Diesel engine fuelled were analysed and compared with diesel fuel operation. The researches established the favourable influences of the hydrogen use on the Diesel engine operating. The obtained results of the experimental investigations highlight the improving of engine performance at fuelling with hydrogen as addition in air.
