Recently, BorgWarner announced that it has signed a supply contract with a core European OEM customer to provide high-performance electronic turbocharger eTurbo for its brand of passenger cars, and plans to start mass production in 2022.
The electronic turbocharger combines an exhaust gas turbocharger and a motor, and the motor is directly coupled to the turbine shaft. At medium engine speed, the exhaust turbine operates. In the case of low speed, the turbocharger is driven by the electronic supercharger to reduce the hysteresis of supercharging and reduce the impact of the turbo when it is working.
At the same time, due to the fast response characteristics of the motor. eTurbo improves transient boost response by more than 200%, which can further promote engine miniaturization. On the premise of not losing power performance, it also brings lower fuel consumption and emissions to the engine, especially suitable for the needs of Miller engines.
In addition, this electronic supercharger also expands the electric energy recovery function, which can capture excess waste gas energy through post-processing technology and precise air-fuel ratio control, and directly convert it into electric energy for use as auxiliary power supply or battery Charging, to better optimize the performance of the vehicle's power consumption.
It is reported that BorgWarner's automotive powertrain and transmission systems, including engines, gearboxes and four-drive systems, as well as in the field of turbocharging, have absolute leadership in the world. Carry out joint R & D and supply cooperation with world-renowned car companies in power system and chassis drive.
