Mechanics use an oscilloscope and observe the stored pattern as the engine spins when performing a dynamic compression test. Regular engine misfires, reduced acceleration, and poor fuel economy are indicators that you need to conduct an engine compression test. Most engines will have a compression ratio that exceeds 100 psi.
Following the above standards, different compression properties (e.g., yield strength, modulus) are estimated from the test data. Moreover, various data processing methods are available to obtain the true stress-true strain curve from the load–displacement data of the compression test [ 6 ].Study with Quizlet and memorize flashcards containing terms like A compression test shows that one cylinder is too low. A leakage test on that cylinder shows that there is excessive leakage. During the test, air could be heard coming from the tailpipe. Which of the following could be the cause? A. Broken piston rings B. Bad head gasket C. Bad exhaust gasket D. An exhaust valve . When manufacturers determine that compression testing is necessary, but no standard test method can be identified, they may develop their own test method. Whatever the procedure, it’s important to test samples consistently and repeatedly, so that trends and outliers can be properly identified from the results data.
