Analysis of Possibilities to Improve Ecological Operating Parameters of Modern Compression – Ignition Diesel Engines

摘要: The aim of this study was to analyse the possibilities improving ecological parameters compression - ignition CI engines. During analysis exhaust gas, attention mainly paid emission nitrogen oxides and carbon black soot. A method proposed reduce above chemical elements in engine fumes by using annular channels on non-working part fuel injector needle applying a platinum catalyst them. task these is mix agitate before injection combustion chamber enlarge contact surface area catalyst. catalytic coating initiate reaction dehydrogenation paraffinic hydrocarbons olefinic ones with free hydrogen molecule. Hydrogen, owing its properties, can shorten period combustible mixture spontaneous delay chamber, which affects entire process improves engine.
