The purpose of Morse Test is to obtain the approximate Indicated Power of a Multi-cylinder Engine. It consists of running the engine against a dynamometer at a particular speed, cutting out the firing of each cylinder in turn and noting the fall in BP each time while maintaining the speed constant.

What is Morse testing?

Morse test is a method to measure the frictional power of a multicylinder SI engine. Morse Test – This test carried out on multi cylinder I.C. engine. In this test, first engine is allowed to run at constant speed and brake power of engine is measured when all cylinders are working and developing indicated power. (

Under what condition Morse test is conducted in the engine?

Detailed Solution. Thus Morse test is used to find out the frictional power of the multi-cylinder engine. First indicated power is found out by cut out one cylinder at a time simultaneously. When all cylinders are working then it is possible to find out the Break Power of the engine.
