Detailed Description
It should be understood that the drawings are for illustrative purposes only and are not intended to limit the application.
Please refer to fig. 1, which is a block diagram of a vehicle using the method for warning the fuel quality of an internal combustion engine according to the present invention, including an internal combustion engine 1, an exhaust gas processor 2 and a controller 3, wherein the internal combustion engine 1 is supplied with oil through an oil tank, which is a basic configuration of the vehicle, but the vehicle has other configurations, which are not shown herein. The controller 3 may record specific events of the excavation processor 2 in processing the excavation process after combustion of the fuel, the triggering of which is related to the quality of the fuel. And comparing the frequency value of the specific event with a normal value, and if the specific event is over-frequent, sending fuel quality early warning information to an information terminal or a cloud end of the vehicle. Specifically, the exhaust gas processor 2 includes an SCR (selective catalytic reduction) and a DPF (diesel particulate filter), and the controller 3 may detect the efficiency of the SCR, and when the efficiency of the SCR is lower than a specific value, the controller 3 regenerates the DPF, so that the efficiency of the SCR is recovered, and records the event as a specific event.
In this embodiment, the controller 3 is further configured to detect and record a refueling event of the internal combustion engine 1, and the controller 3 detects the amount of fuel in the fuel tank of the vehicle after power-up and records a refueling event if the amount of fuel added by the controller 3 exceeds 20% of the amount of fuel last powered-down. 20% is only a criterion for this embodiment, and in other embodiments, the numerical criterion may be other values, and if the amount of this fueling event is less than this value, then it is not recorded as a fueling event. The controller 3 in this embodiment may include an ECU (electronic control system) provided in the vehicle or the internal combustion engine, or may include a controller provided in the cloud. In some embodiments, including the present embodiment, the vehicle is provided with a vehicle locating system, and the controller 3 records the fueling event according to the position information provided by the vehicle locating system, and determines the gas station information, the fueling time, the fueling amount, and the like of the fueling event. Typically, the fueling interval for normal use of the vehicle is not too long, so in other embodiments, the determination of fueling station information may also be provided by the vehicle occupant in memory.
In the present embodiment, the frequency value of the occurrence of a specific event refers to the number of times the specific event occurs within a specific mileage or a specific vehicle operation time or a specific fuel consumption amount. In other embodiments, the frequency value is the mileage of the vehicle or the operation time of the vehicle or the amount of fuel consumed between the present specific event and the last specific event, and the overfrequency is the frequency value of the specific event indicating that the fuel quality is low.
In the present embodiment, the normal value is a preset value preset in the controller 3 according to experience or experiment or calculation, and is preset in the controller 3 when the vehicle is calibrated. Of course, in other embodiments, the normal value is a value calculated from a previous record of the specific event, such as an average of previous 3 specific events.
Of course in other embodiments the criteria for fuel quality may be based on different fuels (diesel, biomass, alcohol), the quality of the fuel being reflected by parameters present in different exhaust treatments, such as regeneration of the DPF due to too high a soot content.
Referring to fig. 2, a flow chart of an embodiment of a method for warning of fuel quality of an internal combustion engine according to the present invention is shown. As shown in the figure, in step 1a, the vehicle controller 3 detects the amount of fuel in the fuel tank after being powered on, if the amount of fuel exceeds 20% of the increase of the fuel when the controller 3 was powered off last time, a refueling event is recorded, and in step 2a, the vehicle controller 3 communicates with the vehicle positioning system to obtain the information of the gas station where the vehicle is currently located, integrates the refueling information, and records the information in the vehicle controller 3. In step 1b, the exhaust gas treatment system 2 detects the SCR efficiency of the vehicle, starts DPF regeneration if the SCR efficiency is lower than a certain value, records the specific event after the SCR efficiency is recovered, and records the fuel consumption between the specific event and the occurrence of the specific event as the frequency value of the specific event. The fuel consumption is then compared to a normal value, and if the fuel consumption is below the normal value, it is determined that the particular event occurred too frequently, and it is determined that the quality of fuel dispensed during the fueling event is likely to be outside of standards, including an out-of-standard sulfur level. In step 2b, the determination result is reported to the controller 3. In step 3, the controller 3 transmits the determination result and the gas station information to the vehicle information terminal or the cloud. In other embodiments, the controller 3 may transmit the determination result and the gas station information to the cloud, and then transmit the result and the gas station information to the vehicle information terminal through the cloud.
Please refer to fig. 3, which is a flowchart illustrating a method for warning of fuel quality of an internal combustion engine according to another embodiment of the present invention. As can be seen from comparison with fig. 2, steps 1a and 2a in fig. 2 are omitted, i.e., in the present embodiment, the controller 3 does not record the refueling information, but judges the refueling information of the warned fuel by the user of the vehicle.
Generally, the above-described warning method of the fuel quality of the internal combustion engine is realized by a computer program product stored in the controller 3.
By the method or program product or controller of the present invention, a determination can be made as to the quality of the fuel being filled. Of course, the system or the user may use the judgment as a warning message, and combine other criteria to make the final judgment.
