Why is Morse test done can it be carried out for all IC engines?
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.
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. The test consists of obtaining the indicated power (IP) of the CI engines without any apparatus.
Which is remain constant during the Morse test when short circuiting spark plug of a cylinder?
Then from total number of cylinders of the engine one of the cylinders is cut out by short circuiting the spark plug. The output is measured by keeping the speed constant. The difference in the outputs is measure of the indicated power of disconnecting cylinders.
What is the purpose of testing an internal combustion engine?
The testing of the engine provides improvement in the performance of the engine by increasing the efficiency and fuel economy of the engine. The continuous testing of engine can maintain fuel efficient operation of the engine and help in diagnosis of the failures of parts or components.
What is the purpose of engine testing?
Testing the operating behavior of internal combustion engines is the common purpose of engine test stands. Various parameters like fuel consumption or exhaust gas behavior were generally measured as a function of torque and rotary speed and mapped in an engine performance map.
What is a Morse test?
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. (
Which parameter is kept constant during the Morse test and why?
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.
How the frictional power is obtained by Morse test?
Morse test is a method to measure the frictional power of a multicylinder SI engine. Where (BP)2,3,4 – Brake power of 2,3 & 4 cylinders only. Thus Morse test is used to calculate IP, FP and mech efficienc by assuming FP of each cylinder remains constant.
What is the main objective of supercharging of the engine?
The objective of supercharging is to increase the charge density of the working medium (air or air-fuel mixture), by any means and with the help of a suitable system, before it enters the work cylinder, i.e., to precompress the charge.
What are the measures of performance in IC engines?
Basic design and performance parameters in internal combustion engines include compression ratio, swept volume, clearance volume, power output, indicated power, thermal efficiency, indicated mean effective pressure, brake mean effective pressure, specific fuel consumption, and more.
