Annotation:
EU authorities have recently started referring to new pollution and climate change control measures more frequently. There is unanimous consensus within the Community on the need for a fundamental reform in the EU transport sector in order to improve air quality in the cities of Europe. One of the measures put forward is formation of a common market of new vehicles that use low-polluting fuels, such as hydrogen, biofuel and electricity, instead of fossil fuel. Application of electrolysis-generated hydrogen in ICE is named as a possible solution. Application of pure hydrogen in motor vehicles is subjected to certain limitations resulting from complex modifications of internal combustion engines ICE that are required in order to adapt motor vehicles to high flame speed of hydrogen, high pressure and high temperature inside the combustion chamber.
As a result, alternative options for application of hydrohen in ICE are explored. It is performed detailed practical tests in order to assess the effect of electrolysis-generated hydrogen on the combustion process in a gasoline/diesel ICE. Hybrid ICE-powered passenger car operating on gasoline/diesel and hydrogen has been used for the tests. The following aspects have been covered in the work: engine power variation at different throttle valve positions, dependence of power on crankshaft RPM in case of application of gasoline with 5% hydrogen additive, analysis of exhaust gas temperature variations.
Numerical exhaust gas prediction model has been developed based on the data generated during the experiment in order to assess three different parameters: engine RPM, hydrogen content in the mixture, and fuel consumption. Maximum hydrogen concentration in the combustible mixture that improves ecological and economic indicators of a gasoline engine has been determined to be 5%.
