  • Patent number: 10760464
    Abstract: Methods for monitoring and/or regenerating a selective catalytic reduction particulate filter (SCRF) are provided. The SCRF comprises a porous filter substrate and a catalytic composition capable of reducing NOx applied thereto. Methods include determining a SCRF pressure differential (dP) and determining the SCRF soot loading using a 1st SCRF dP map if the SCRF has not been degreened, or a 2nd SCRF dP map if the SCRF has been degreened. The SCRF has been degreened if one or more of a degreening cumulative time and temperature threshold has been achieved and a filter regeneration count threshold has been achieved. The 1st and 2nd SCRF dP maps correlate SCRF dP and one or more of SCRF temperature, exhaust mass flow, and exhaust volumetric flow to a SCRF soot loading. The method can optionally further include initiating a filter regeneration if the determined SCRF soot loading is above a soot loading threshold.

  • Publication number: 20200182109
    Abstract: An engine oil strainer includes a lubricating oil passage, and an oil inlet and an oil outlet which are respectively disposed at two ends of the lubricating oil passage. The engine oil strainer further includes a check valve which is disposed at the oil inlet and which only allows a lubricating oil to flow into the lubricating oil passage. Also disclosed herein are a lubrication system employing the engine oil strainer, and an internal combustion engine having the lubrication system. When the internal combustion engine stops operating, the lubricating oil flows back from the oil outlet into the engine oil strainer. Since the check valve is disposed at the location of the oil inlet of the engine oil strainer, the lubricating oil flowing back into the engine oil strainer is not capable of proceeding to flow back from the oil inlet into the oil pan.
