General Motors for partnership with BorgWarner Transmission Systems

BorgWarner Stop/Start Accumulator Solenoid Valve (Eco-Launchâ„¢ Solenoid Valve)

General Motors came to BorgWarner with a knowledge of hydraulic accumulators, and a vision of using one to rapidly prime an automatic transmission to advance the performance of start/stop hybrid technology. That however required a valve that had extremely low leakage and allow a rapid discharge of the accumulator. Starting with challenging performance specifications, BorgWarner worked closely with GM to develop and validate a solenoid valve that could deliver high performance as well as be efficiently packaged. The PACE judges and BorgWarner are pleased to recognize GM's close partnership from encouraging the initial innovation to validating the final product for production.
