Abstract:
The newly developed handheld fuel analyzer helps determine the Pump Octane Number (PON), Research Octane Number (RON), and Motor Octane Number (MON) of unleaded gasoline, ethanol blended gasoline, leaded gasoline, and diesel fuels, as well as the Cetane Number. This handheld device has been shown to have excellent accuracy and repeatability comparable to ASTM engine test techniques (ASTM D2699, D2700). ASTM D2699 is a test method for the Research Octane Number of Spark-Ignition Engine Fuel, while ASTM D2700 is a test method for the Motor Octane Number of Spark-Ignition Engine Fuel. The octane number scale ranges from 0 to 120, while this test method's working range for R.O.N. is between 40 to 120. Typical commercial fuels for spark-ignition engines have R.O.N ratings of 88 to 101. Testing of gasoline blend stocks or other process stream ingredients might result in R.O.N. ratings at various levels. Over 60 countries across the world utilize handheld octane analyzers, with about 45 states in the United States using them. This design can test the octane value of gasoline quickly, easily, and precisely without causing any damage to the sample. Handheld octane analyzers have dominated portable gasoline analysis in fuel labs, research institutions, repair shops, and pipelines, along with being extremely easy and convenient to use. Improved NearIR optics and a user-friendly interactive display have also made it possible to determine fuel quality quickly and accurately at the pump, rack, terminal, and in production. The details of this innovative technique will be discussed in this poster.
