Abstract

A method and system of determining a maximum oil change limit for an engine considering the engine operating environment and location is provided. An engine location indicator is generated in response to a trigger, using a locating device in communication with a controller. The locating device may include a global positioning system (GPS) receiver. The engine may be an internal combustion engine on a vehicle configured as one of a hybrid vehicle and an extended range electric vehicle. The trigger may be one of a calendar time, a key-on event, an oil change event, and a signal provided by the controller. The controller may generate the maximum oil change limit of the engine using one or more oil change indices, each defined by the engine location and / or time in location. The maximum oil change limit and / or an oil change limit alert may be provided as an output of the controller.

Description

technical field [0001] The present invention relates to a method and system for determining an oil change limit for an engine. Background technique [0002] The oil filter assembly and lubricating oil for the vehicle's internal combustion engine (ICE) are consumables that have a limited useful life and thus require periodic replacement during the life of the engine to avoid damage to the engine and / or associated engine components. damage. At the end of its useful life, the oil can lose its ability to adequately lubricate the engine, and engine components can wear or seize. An oil filter assembly, also commonly referred to as an oil filter, or filter, at the end of its useful life, may lose its ability to filter impurities from the oil, water degradation of the filter media may occur, the filter may become clogged, and Oil flow through the engine is reduced or stopped, or the filter may otherwise deteriorate so that oil is leaked from the engine through the canister, connec...
