What part should be removed to test cylinder compression on a diesel engine?

Select one:

A. Injector

B. Intake valve rocker arm and stud

C. Glow plug

D. Glow plug or injector

Answer :

Final answer:

To test cylinder compression on a diesel engine, you can remove either the injector or the glow plug to allow access for the compression gauge. The intake valve rocker arm and stud do not provide direct access to the cylinder. Therefore, the most accurate choice is to remove either the glow plug or the injector.


Explanation:

Cylinder Compression Testing in Diesel Engines


When testing cylinder compression on a diesel engine, you may need to remove certain components to allow access to the cylinder for accurate measurement. The options provided in your question all pertain to parts associated with the combustion process in diesel engines.



Components That Can Be Removed



  • Injector: Removing the injector allows for direct access to the combustion chamber, which is essential for using a compression tester.

  • Glow Plug: Like the injector, the glow plug can also be removed for testing, enabling a compression gauge to be inserted into the cylinder.

  • Intake Valve Rocker Arm and Stud: This component is generally not removed for compression testing, since it does not provide direct access to the cylinder.



In the context of your question, the best answer is d. Glow plug or injector, as both the glow plug and the injector provide necessary access for testing cylinder compression in a diesel engine.
