The experimental research on the vibration monitoring and diagnosis technology of valve components for a high speed diesel engine by using the surface vibration signals on a cylinder head is presented. The excitation characteristices causing the cylinder head vibration were analyzed. And the fault simulation experiments, such as single cylinder misfire and valve component faults, were carried out. The surface vibration signals on the cylinder head with the different fault conditions were measured and analyzed, the characteristic parameters for diagnosing faults were extracted, and the relationships between the characteristic parameters and the different types and different degrees of faults were established.
