Problems solved by technology

However, these methods rely on the operator to check the engine oil level and therefore can result in infrequent oil level checks, low or high engine oil levels, and ultimately damage to the engine and / or emission control system

Embodiment Construction

[0049] The following description is merely illustrative in nature, and is in no way intended to limit the present disclosure, its application or uses. For clarity, the same reference numbers are used in the drawings to indicate similar elements. As used herein, at least one of the phrases A, B, and C should be understood to mean logical (A or B or C), using a non-exclusive logical OR. It should be understood that the steps in the method can be executed in a different order without changing the principle of the present disclosure.

[0050] As used herein, the term module can refer to a part that is or includes: application specific integrated circuit (ASIC); circuit; combinational logic circuit; field programmable gate array (FPGA); processor (shared, dedicated or grouped) that executes code ); other suitable components that provide the required functions; or a combination of some of the above, such as a system on a chip. The term module may include memory (shared, dedicated, or...

Abstract

A system includes a user interface module, a level determination module, and a level storage module. The user interface module outputs an oil level request based on user input. The level determination module determines N oil levels of an engine. N is an integer greater than one. The level storage module stores the N oil levels and outputs one of the N oil levels in response to the oil level request.

Description

Technical field [0001] The present invention relates to an engine control system and method, and more specifically, to a system and method for monitoring engine oil level. Background technique [0002] The purpose of the background art description provided herein is to give the background of the present disclosure in general. The work of the currently signed inventors, to the extent described in the background art section, and aspects of the present invention that may not constitute prior art at the time of submission are not expressly or implicitly accepted as prior art of the present disclosure. [0003] Engine oil is usually circulated in the engine to lubricate the moving components in the engine. Generally, an oil pump pumps engine oil from an oil storage tank to various other locations within the engine. Gravity causes the engine oil to return to the oil storage tank. When the engine is turned off, the oil pump no longer pumps engine oil, and therefore most of the engine o...
