Abstract
The pressure change in the combustion chamber of a sample engine is correlated with the amplitude and frequency of the vibrations of various engine components, an equivalent level representative of the level of stresses or load on the components is computed and said equivalent level is used with respect to same-type engines, especially high-powered Diesel engines, in actual service, to make immediate decisions about modifying driving parameters or longer-effect decisions concerning preventive or remedial maintenance.
