Products and processes for analyzing octane content
Products and processes are provided herewith for analyzing octane content in a fuel sample that include the step or steps of receiving an octane measurement of a fuel sample from a octane analyzer, rounding the octane measurement to a nearest recognized octane rating, comparing the rounded octane measurement with a listed octane rating for the fuel sample, and communicating results of the comparison to a user of the octane analyzer. The octane analyzer may be incorporated into a fuel pump or a vehicle. The results of the comparison may also be used to adjust the vehicle operating parameters to account for the actual octane rating of the fuel dispensed into the vehicle.
1. A vehicle comprising:
an engine;
a fuel tank;
an octane analyzer to detect an octane rating of fuel and round the octane rating to a nearest recognized octane rating;
a receptacle having an inlet to allow the fuel to enter the receptacle as fuel is being pumped into the fuel tank and an outlet leading into the fuel tank to allow the fuel to exit the receptacle and enter the fuel tank;
a valve mechanism to manage an amount of fuel flowing through the inlet, as fuel is being pumped into the fuel tank, and manage the amount of fuel flowing through the outlet of the receptacle and back into the fuel tank, such that the amount of fuel in the receptacle enables the octane analyzer to identify the octane rating of the fuel;
at least one processor to adjust an ignition timing of the engine in accordance with the octane rating identified by the octane analyzer; and
wherein the valve mechanism is configured to reduce the amount of fuel in the receptacle while the octane analyzer identifies the octane rating of the fuel.
2. The vehicle of claim 1 , further comprising the fuel tank and the fuel pump to periodically pump fuel from the fuel tank into the receptacle.
3. The vehicle of claim 1 , wherein the nearest recognized octane rating is a two digit octane rating.
4. The vehicle of claim 1 , wherein the octane analyzer is further configured to compare the identified octane rating with an expected octane rating.
5. The vehicle of claim 4 , further comprising a display to render a visual representation of the octane rating.
6. The vehicle of claim 5 , wherein the visual representation of the octane rating comprises a bar graph or a line chart.
7. The vehicle of claim 1 , wherein the valve mechanism is configured to increase the amount of fuel in the receptacle in response to the octane analyzer identifying the octane rating of the fuel in the receptacle.
8. The vehicle of claim 1 , wherein the octane analyzer periodically identifies the octane rating of fuel that flows through the receptacle.
9. A method comprising:
causing, via a valve mechanism, a flow of fuel to a receptacle to be reduced, the receptacle having an inlet to allow the fuel to enter the receptacle as fuel is being pumped into a fuel tank and an outlet to allow the fuel to exit the receptacle into the fuel tank;
determining, by at least one processor, whether an amount of fuel in the receptacle at a given time meets a threshold amount;
identifying, by the at least one processor, an octane rating of the fuel in the receptacle, while the flow of fuel to the receptacle is reduced and when the amount of fuel meets the threshold amount; and
adjusting, by the at least one processor, a parameter of an engine in accordance with the identified octane rating.
10. The method of claim 9 , further comprising rounding, by the at least one processor, the octane rating to a nearest recognized two digit octane rating.
11. The method of claim 9 , further comprising comparing, by the at least one processor, the octane rating with an expected octane rating.
12. The method of claim 9 , further comprising rendering, by the at least one processor, a visual representation of the identified octane rating.
13. The method of claim 12 , wherein the visual representation of the octane rating indicates whether the octane rating meets an expected octane rating.
14. The method of claim 9 , further comprising periodically identifying, by the at least one processor, the octane rating of the fuel that flows through the receptacle.
