What Does ORI Stand For?
ORI stands for Octane Requirement Increase
ORI, or Octane Requirement Increase, refers to the increased fuel octane rating needed by an engine to optimize performance, efficiency, and emissions. This phenomenon typically occurs in high-compression or turbocharged engines, where the fuel's resistance to knocking becomes critical for maintaining optimal engine operation. Understanding ORI is essential for automotive engineers and manufacturers to ensure compatibility between engine design and fuel specifications.
