Study of hydrogen gaseous fuel influence on the thermal condition of a diesel engine

Abstract

Abstract The current article presents experimental results for the thermal condition of a diesel-hydrogen powered engine. The object of the study is an air-cooled single cylinder diesel engine. A quantitative assessment of the engine thermal condition is made. It is based on four engine body part temperatures and the temperatures of exhaust gases and engine oil. The study is carried through by comparing the engine indexes via regulation characteristics as a function of the hydrogen mass content and load characteristics with constant hydrogen content. Experimental results as a function of engine speed at constant engine power are also presented. The data registered during the experiment is for two different diesel injection advance angles. A temperature for one location on the combustion chamber roof (cylinder head) is calculated. The results of the experiment are presented in charts.
