Embodiment Construction

[0013] figure 1 The operation operation of the device 100 on the vehicle (not shown) is displayed. Such as figure 1 As shown, the device 100 includes a GPS device 60, a map database 12, and a lookup table 50. It is also possible that a wireless communication device 40, such as a mobile device, is externally connected to the device 100. The device 100 uses the GPS device 60 or the wireless communication device 40 to obtain location data, so as to use the map database 12 to locate vehicles on the driving section. It is also possible that the device 100 can communicate with a navigation system to obtain location information, because the navigation system already has a GPS device 60 and a map database 12 for displaying directions.

[0014] The device 100 is an electronic control unit or engine management unit with a microprocessor or microcontroller, and the microprocessor or microcontroller is equipped with standard peripheral equipment and components. The device 100 controls th...

Abstract

A device 100 in a vehicle comprises a detection device 10 for detecting fuel refilling of the vehicle, a position determining device 15 for determining the position of a fuel station for refilling fuel for the vehicle, an indicator 20 for indicating the fuel quality based on the position of the fuel station, and an adjusting device 25 for adjusting the regeneration frequency of exhaust catalysts 70 in the vehicle according to the indicated fuel quality.

Description

Technical field [0001] The invention relates to the regeneration of exhaust gas catalysts based on fuel quality. Background technique [0002] Since the beginning of the industrial revolution, air pollution has increased rapidly due to the rapid increase in the use of fossil fuels. In particular, the automobile industry has become a major consumer of fuel oil and a major contributor to air pollution. This problem is essentially global in nature, because car emissions cause an increase in greenhouse gases in the atmosphere, leading to global warming. [0003] The adulteration of automobile fuels, namely gasoline and diesel, will lead to an increase in pollutants and consequently adverse effects on public health. Gasoline mixed with kerosene can increase emissions, because kerosene is more difficult to burn than gasoline, which leads to higher levels of HC, CO, and PM. The high content of sulfur in kerosene can deactivate the catalyst and reduce the ability to convert pollutants e...
