Problems solved by technology

This means that for many engines the oil is changed before it needs to be changed, with the disadvantage of causing unnecessary engine downtime
This is very important if the engine is used in a commercial environment, in addition, unnecessary oil changes will also increase the operating costs of the engine

Embodiment Construction

[0026] refer to figure 1 with Figure 4 , an internal combustion engine is shown in the form of a diesel engine 5 having an electronic control unit or controller 10 connected thereto for controlling the operation of the engine 5 and performing various data processing functions. The controller 10 is operatively connected to and controls the output of a variable displacement oil pump 15 arranged to pass from an oil reservoir or sump 6 through an oil cooler 7 and a main or full flow filter 8 Pump oil to engine 5. Oil circulates through the engine 5 and back to the sump 6 in a conventional manner.

[0027] The full flow filter 8 is designed to capture large debris in oil without excessive back pressure or pressure loss, so it has a relatively coarse filter media so that it only captures debris with a particle size greater than about 15 microns . Therefore, under normal operating conditions where carbon black is dispersed in oil in particulate form, the full flow filter 8 is to...

Abstract

The present invention discloses a system and method capable of more accurately estimating the concentration of carbon black in oil of an engine (5). This estimate can be used to warn the operator of the engine (5) when an oil change is required and to control the removal of soot from the oil. The invention also provides a method for alerting the operator of the engine (5) when the soot removal filter (16) needs to be replaced.

Description

technical field [0001] The present invention relates to internal combustion engines, and more particularly to a system and method for estimating the accumulation of soot in oil lubricating the engine so as to more accurately determine when the oil needs to be changed. Background technique [0002] Carbon black is known to accumulate in the oils of internal combustion engines, especially diesel engines, under certain operating conditions. As the amount of carbon black increases, it will have a detrimental effect on the durability of the engine. To prevent excessive wear of the engine, the oil must be changed before the soot concentration in the oil reaches a critical predetermined limit. The rate at which soot accumulates varies depending on a number of factors including vehicle condition and engine age. To prevent the risk of excessive soot loading and resulting engine damage, oil change intervals are usually set on the basis of worst case soot accumulation in the oil. Th...
