Why does sequentially increasing the mechanical compression ratio during a Research Octane Number (RON) laboratory test challenge the antiknock performance of a test fuel?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1It inherently ensures a maximized thermal efficiency regardless of fuel composition
- 2It raises end-gas temperature and pressure, increasing the likelihood of premature auto-ignition knocking✓
- 3It reduces the relative concentration of elemental sulfur within the combustion chamber
- 4It artificially elevates the underlying cetane rating of the volatile components
Correct answer
It raises end-gas temperature and pressure, increasing the likelihood of premature auto-ignition knocking
