AI Technical Summary
Technical Problem
Traditional whole-machine level testing to verify engine timing system wear issues is time-consuming, costly, and lacks specificity, making it difficult to effectively select suitable technical solutions.
Method used
By replacing the timing system on the engine, the load conditions in the maximum chain force speed range are simulated. Combined with the whole vehicle road spectrum data, bench tests are conducted to calculate the cumulative number of runs in the maximum chain force speed range for rapid verification.
Benefits of technology
It shortens the troubleshooting cycle, improves verification efficiency, reduces costs, effectively assesses the potential reliability of timing systems, and provides a rapid verification method.

Abstract
The application relates to an engine timing system wear verification bench test method, which replaces the original timing system in an engine with a test timing system to form a test engine; obtains a test speed interval and a test load working condition; obtains a test cumulative running number of the test speed interval in vehicle road spectrum data of the original engine; performs a bench test of the test engine; after the bench test is completed, the wear risk of the test timing system is analyzed and evaluated. The application greatly improves test verification efficiency.
