Abstract

The diesel engine vibration is one of the main problems of engine damage. When the hydrogen-diesel dual fuel is used, it may affect the engine vibration. Therefore, it is necessary to study the effect of hydrogen-diesel dual fuel. The regression analysis is used to find the relations between hydrogen percentage and the engine vibration. The results for all cases found that the relation between the Average Peak Acceleration (APA) and hydrogen percentage (%H2) can predict by using linear equation with average coefficient of determination (R2) = 0.8973 or 2nd polynomial equation with R2 = 0.9592. All graphs are the decreasing function. APA can decrease by increasing %H2. The relation between the average peak acceleration and hydrogen percentage can predict by using linear equation or 2nd polynomial equation. The average peak acceleration can decrease by increasing hydrogen percentage. In the other word, the engine vibrations can decrease by increasing hydrogen percentage.
