Cummins Fuel Systems designs and manufactures high-pressure diesel fuel systems that must survive high-cyclic pressures during operation. Shot peening is
employed as a surface strengthening technique on pressurebearing surfaces of fuel system components where fatigue failure, due to alternating pressure, is most likely to occur. Cummins Fuel Systems has been a long-standing supporter of Purdue Senior Design Projects and they sponsor a project almost every year. Precision shot peening and the measurement of the resulting properties are topics of special interest to the company. The following is a reprint of the students’ research poster.
