Estimating the term…
A method of estimating an operational aspect of an internal combustion engine is disclosed, wherein the engine comprises a crankcase enclosing at least part of a crankcase volume, a crankcase ventilation outlet connected to the crankcase volume, and a gas cleaning assembly comprising an oil separator unit and a pump unit configured to pump gas from the crankcase volume to the oil separator unit via the crankcase ventilation outlet. The method comprises the steps of obtaining data indicative of a pumping rate of gas pumped by the pump unit and estimating the flow rate of gas through the crankcase ventilation outlet based on the data. The present disclosure further relates to a computer program, a computer-readable medium, a control arrangement, an internal combustion engine, and a vehicle.
A method of estimating an operational aspect of an internal combustion engine, wherein the internal combustion engine comprises a crankcase enclosing at least part of a crankcase volume, a crankcase ventilation outlet connected to the crankcase volume, and a gas cleaning assembly comprising an oil separator unit and a pump unit configured to pump gas from the crankcase volume to the oil separator unit via the crankcase ventilation outlet, and wherein the method comprises:
A computer program product stored on a non-transitory computer-readable medium, said computer program product for estimating an operational aspect of an internal combustion engine, wherein the internal combustion engine comprises a crankcase enclosing at least part of a crankcase volume, a crankcase ventilation outlet connected to the crankcase volume, and a gas cleaning assembly comprising an oil separator unit and a pump unit configured to pump gas from the crankcase volume to the oil separator unit via the crankcase ventilation outlet, wherein said computer program product comprising computer instructions to cause one or more computer processors to perform the following operations:
(canceled)
A control arrangement for estimating an operational aspect of an internal combustion engine, wherein the internal combustion engine comprises a crankcase enclosing at least part of a crankcase volume, a crankcase ventilation outlet connected to the crankcase volume, and a gas cleaning assembly comprising an oil separator unit and a pump unit configured to pump gas from the crankcase volume to the oil separator unit via the crankcase ventilation outlet, and wherein the control arrangement is configured to:
An internal combustion engine comprising:
A vehicle comprising an internal combustion engine comprising:
