Summary:

High particulate emissions from vehicles powered by diesel engines have led to the evolution of many new technologies as well as legal restrictions. One of the ways to reduce emissions from combustion of diesel fuel is to use the dual fuel system. Methane and hydrogen are most often considered as additional fuel for use in a diesel engine. The combustion process and thus the emission are determined i.a. by fuel atomisation and injection methods. The motivation to undertaking the research is the need to define how the applied hydrogen injection will influence on the particulate emission during the combustion process in a dual fuel diesel engine. Research has been conducted to compare the particulate emissions during engine operation with the direct and indirect injection of hydrogen. The research object is a four-cylinder, four-stroke ADCR engine produced by Andoria-Mot with a displacement of 2636 cm3. Glow plugs were replaced by compressed hydrogen injectors with a dedicated adapter. The function of glow plugs was taken over by a commonly used system for heating the intake air. The SEMTECH Ecostar exhaust analyzer was used for particulate emission tests. All samples were recorded at a frequency of 10 Hz. The following analyzer modules were used: Power Distribution Module, Micro Proportional Sampling System, Particulate Filter System, Fuel Economy Meter and Continuous Particulate Measurement. The experiment controlled the torque and changed the hydrogen dose. Examinations were conducted at the 1500 rpm. Hydrogen was injected using the original research injector. The injection time and the maximum hydrogen dose were determined experimentally based on preliminary studies. The analysis of the obtained results was carried out at all measurement points. The limitations of the tests were defined and recommendations for further work were formulated
