Problems solved by technology

Vehicle manufacturers can recommend higher-octane fuels to reduce the likelihood of knocking in some vehicles, but since higher-octane fuels are generally more expensive than lower-octane fuels, higher-octane fuels can increase vehicle operating costs
However, if the vehicle is not operating at a higher engine speed and torque, the increased cost of higher octane fuel will be unnecessary since the vehicle will not knock at lower speed and torque

Embodiment Construction

[0015] The following description relates to systems and methods for presenting options and selecting a fuel with a higher octane rating or a lower octane rating based on past or future vehicle travel routes. figure 1 An example vehicle is shown for which the cost of operating the vehicle on a prescribed travel route on higher octane fuel or lower octane fuel may be estimated. An example display panel for presenting estimated vehicle operating costs is in Figure 2A and Figure 2B shown in . figure 1 A vehicle may include an engine and drive train such as image 3 and Figure 4 shown in . exist Figure 5 A method for presenting and selecting vehicle refueling options for fuels with higher or lower octane ratings based on past travel routes or future travel routes is shown in . Figure 5 The method of can be executed via a controller that acts as Figure 1 to Figure 4 part of the system shown in . at last, Image 6 shown for the Figure 5 method and with Figure 5 A m...

Abstract

Methods and systems are presented for providing information to a vehicle driver allows the driver to make an informed decision regarding selecting higher or lower octane fuel to operate the vehicle. In one example, the driver is presented fuel cost per unit distance traveled based on operating the vehicle on higher octane fuel and lower octane fuel.

Description

technical field [0001] The present description generally relates to methods and systems for displaying fuel octane options to a driver of a vehicle so that the driver can make more informed fuel choices. Background technique [0002] Gasoline fuel can be sold in various octane levels. Higher octane fuels tend to be more resistant to knock than lower octane fuels. Knock is a popping sound produced by the engine and caused by a rapid pressure rise in the cylinder caused by the temperature and pressure in the cylinder caused by the flame front passing through the cylinder via spark ignition Increase to ignite the exhaust in the cylinder. Knock can cause engine degradation and is often prevented at higher intensity levels. Knock occurs more frequently at higher engine speeds and torques because cylinder wall temperatures and cylinder air-fuel mixture temperatures can increase at higher engine speeds and torques. Engine compression ratio can also affect the engine's propensit...
