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.

Summary
The engine vibration is one of the main factors in engine design and engine maintenance (Cheng et al, 2012; Taghizadeh-Alisaraei et al, 2012). The engine vibration can measure by using the displacement sensor, the velocity sensor (Cheng et al, 2012), the accelerometer (Taghizadeh-Alisaraei et al, 2012; Barelli et al, 2009; Carlucci et al, 2006), the engine acoustic pressure (Barelli et al, 2009). The alternative fuels are using to mix with diesel oil as the dual fuels for decreasing diesel oil consumption (Lata et al, 2011; Escalante and Fernandez, 2010; Selim, 2001; Banapurmatha et al, 2008; Huzayyin et al, 2004). The hydrogen-diesel dual fuel is one of the main choices because hydrogen can be produced from various sources such as water
