Embodiment Construction

[0058] Before elaborating the present invention, some definitions are provided, which will help in understanding the present invention.

[0059] The term "vehicle" as used herein includes any conveyance or model of conveyance originally designed for the purpose of moving one or more tangible objects such as people, animals, goods under power. Typical vehicles may include, but are by no means limited to, cars, trucks, vans, motorcycles, buses, automobiles, trains, rail vehicles, boats, boats, marine vehicles, airplanes, and the like.

[0060] As used herein, the term "fuel" means a hydrocarbon-based fluid (usually a liquid) that is used as the basis for internal combustion reactions within an automobile engine. Suitably the internal combustion engine is of the spark-ignited or compression-ignited type. For spark ignition engines, the fuel will suitably comprise gasoline or refined petroleum. In some examples derived from biological sources, gasoline may be supplemented with e...

Abstract

Disclosed is a method to determine whether fuel quality falls below a predetermined quality threshold during or after a vehicle refuelling event. The method comprises determining that a novel fuel has been introduced into a vehicle; undertaking at least one measurement of the novel fuel in order to determine at least one parameter of the novel fuel, wherein the parameter is associated with a property of the fuel; comparing the at least one parameter of the novel fuel with a threshold reference parameter in order to determine whether fuel quality falls below a predetermined quality threshold; and providing an alert to the operator of the vehicle to indicate whether the fuel quality of the novel fuel falls below the predetermined quality threshold.

Description

technical field [0001] The present invention relates to a method and system for determining fuel quality in a vehicle during or after a refueling stop. Aspects of the invention relate to methods, systems, control modules, engine control units and vehicles. Background technique [0002] In the European Union (EU) and the United States, the establishment and maintenance of high standards for motor fuels such as gasoline / crude oil (or "petroleum") and diesel has been significantly advanced in recent years. The increasingly stringent standards that liquid fuels must meet are driven in part by the drive to reduce the environmental impact of motor vehicles and improve the sustainability of remaining hydrocarbon sources. For example, the sale of petroleum containing additives such as tetraethyl lead has been banned for most vehicles within the European Union since 2000. EU-wide directives such as 98 / 70 / EC and 2005 / 55 / EC set out strict environmental norms which have implementation...
