# What is Morse test in IC engine?

## What is Morse test in IC engine?

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 are the concluding remarks about Morse test?

CONCLUSION After performing the Morse test we can conclude that it is the most useful engine test to calculate the performance of the engine mainly the Multicylinder engines and in future the use is going to increase and it is very easy to calculate the performance of the engine.

Is Morse tested for single cylinder engine?

Solution(By Examveda Team) Morse test can be conducted for Multi cylinder engines The purpose of Morse test is to obtain the approximate indicated power of a Multi cylinder engine.

### When the Morse test can be used to evaluate the performance of an engine?

The Morse test is used for measuring the indicated power of the multi-cylinder engines. This test measures the indicated power by cutting out the spark plug of the cylinder by keeping the speed of the engine constant.

### Which of the following Morse test is applicable?

1. To which of the following Morse test is applicable? Explanation: The Morse test is used to measure the indicated power (IP) from multi-cylinder CI engines.

What are the assumptions made in Morse test?

The assumption made on the test is that frictional power is depends on the speed and not upon the load on the engine .

#### Which of the following engine on which Morse test can be conducted?

Morse test can be conducted for multicylinder petrol and diesel engines. So, D is the correct answer.

#### Why is Morse not important for a single cylinder?

But in case of a single cylinder engine if the fuel supply is cut off no output is obtained to conduct the performance test. Therefore Morse test is not suitable for a single cylinder engine. Morse test is used to determine individual bp for a multiple cylinder engine, by cutting one at a time.
