(54) Improvements in and relating to prime movers


(57) A method of determining the probable wear experienced by a prime mover having moving parts which involves measuring the useful life of the prime mover under one particular operating condition and thus one rate of energy input e.g. fuel to arrive at an optimum life and then measuring the life under other operating conditions such as load and environment to obtain compensating factors which can be applied to the energy input under these operating conditions to get a measure of the probable accumulated wear and thus its potential future useful life.
