Explanation:

Morse Test:

• The Morse test is a test conducted to determine the power developed in each cylinder in a multi-cylinder IC engine.
• In this test first of all the power developed by all the cylinders together is determined experimentally.
• Then the power of the individual cylinders is determined by cutting off the power supply to the spark plug of the cylinder under test.
• Then the power developed by the engine with the remaining cylinders is determined experimentally and this value is subtracted from the first value and this gives you the power developed in the cylinder, whose spark plug was cut off.
• Similarly, this test is carried out on all the cylinders of the SI and CI engine individually.
