  • Method for starting an internal combustion engine for a motor vehicle, and drive train for a motor vehicle
    Patent number: 10900453
    Abstract: A method is provided for starting an internal combustion engine with a driveshaft for a motor vehicle. A starting process is carried out, by which the internal combustion engine is started and thereby transferred from a deactivated state into a powered operation, wherein the starting process is carried out by a pinion starter and by a belt starter, by which the driveshaft is driven during the starting process.
    Type: Grant
    Filed: December 13, 2019
    Date of Patent: January 26, 2021
    Assignee: Bayerische Motoren Werke Aktiengesellschaft

  • Pinion starter gearing having corrected gear geometry
    Patent number: 10605219
    Abstract: A pinion starter drive for an internal combustion engine is provided. The pinion starter drive includes a drive pinion and a starter gear. At least one tooth of the drive pinion has a drive actual profile, and at least one tooth of the starter gear has a starter actual profile. A sum of at least one discrete value of a deviation of the drive actual profile from a drive target profile in the drive pinion tooth root region and at least one discrete value of a deviation of the starter actual profile from a starter target profile in the starter gear tooth tip region is less than 0. A method of manufacture of a pinion starter drive includes selecting a drive pinion and a starter gear from a plurality of gears having a deviation sum less than zero.
