BMW E-Compressor Patent: More pressure below
BMW E compressor patent
More pressure below
BMW has patented an electrically driven compressor which, in conjunction with an internal combustion engine, is supposed to achieve high torques at low speeds.
August 19, 2019
The BMW patent dates back to January 2018, but was not disclosed until August 2019. The patent describes a motorcycle with a supercharged internal combustion engine. In this case, the charger is not an exhaust gas turbine, but a purely electrically operated compressor.
More torque, fewer emissions
The patent specification also makes it clear that this compressor does not increase the peak output of the combustion engine described – BMW shows an S 1000 RR in the patent specification – but should provide more full torque at low speeds. In addition, the e-compressor should ensure particularly efficient and thus economical and low-CO2 operation. As a high-speed concept, the combustion engine itself remains a pure sports engine, which only achieves its peak performance and maximum torque at five-digit speeds. The e-compressor, which is completely mechanically decoupled from the combustion engine, shovels plenty of Nm into the drive train at low to medium speeds, electronically controlled. In the best case, this results in a broad torque plateau, which also benefits the driveability.
A small e-turbine could also be operated with a 12 V on-board network; a 48-volt sub-board network would also be conceivable. The fact that BMW is patenting such a technology does not mean that the Bavarians are also implementing the concept in series production. But it shows which ways are being considered to make combustion engines fit for the future.
