Bayerische Motoren Werke, commonly known as BMW, is one of the most successful and popular automobile brands on the market. Their revolutionary designs and models have separated them from the competition for years, and their motto of building “The Ultimate Driving Machine” solidifies their goal of making a “driver’s” vehicle.
As the worldwide trend of going green continues to gain popularity, BMW is most certainly participating. With several new patents pending and others already published, they are aiming to change the way engines are built and how fuel is consumed. Needless to say, we immediately were interested in performing a Patent Rank analysis on their portfolio, and believe us when we say, we were impressed! One particular patent that drew our interest is patent #8,262,548: Supercharged internal combustion engine and method for monitoring whether the crankcase vent has been connected.

About Patent #8,261,548:
A supercharged internal combustion engine in a motor vehicle includes a venting device for the crankcase of the internal combustion engine and a compressor for supercharging the internal combustion engine. A discharge opening for discharging the crankcase gas is provided upstream of the compressor and a sensor for determining the charge pressure of the compressor is provided downstream of the compressor. The discharge opening is connected to the crankcase by a first connection for the airflow, in particular a hose connection. In order to cost-effectively monitor the venting of the crankcase of the internal combustion engine, an opening, to which the charge pressure of the compressor is applied, is provided downstream of the compressor. The first connection for the airflow includes a closing device for closing the opening to which the charge pressure is applied, wherein the closing device closes the opening if the first connection is connected to the discharge opening.
In Layman’s Terms:
The purpose of this patent is to provide cost-effective monitoring of the venting of the crankcase of the internal combustion engine. In other words, BMW has invented a way to monitor their supercharger through an output signal of the charge pressure sensor that is used to check whether the charge pressure has dropped below a predefined threshold value. This improvement enables a method for monitoring whether the first connection has been connected to the discharge opening.
Based on the MyPatentAssets analysis and our own personal research and evaluation, we conclude that patent #8,261,548 holds significant value.
