    Abstract :

    The single cylinder engines are extensively used in agricultural areas for several purposes such as water pumping, harvesting machines, spraying of pesticides etc. The use of diesel as fuel and having only one cylinder makes them an economic alternative due to their low investment cost and limited fuel consumption. Therefore these engines are important auxiliary agricultural tool for rural areas. Because of excessive usage and overloading in field applications more failures are reported on different engine components. Crankcase is located at the bottom of the cylinder block. It can be molded as a part of a block or bolted on separately. . The failure investigation includes visual inspection, chemical composition analysis, micro-structure examination, hardness determination, static analysis as well as dynamic analysis (modal and harmonic analysis). In this paper, failure investigation has been conducted on crankcase of single cylinder high speed diesel engine by modal analysis. Modal analysis determines the vibration characteristics (natural frequency and mode shape) of crankcase.
