Eco-launch solenoid for transmissions
Company: BorgWarner Transmission Systems
What: Better valve reduces lurch in stop-start engines
Innovation: When a stop-start engine stops, the transmission fluid begins to lose pressure. This can cause the auto to lurch when the engine and vehicle restart. A hydraulic accumulator can efficiently maintain the pressure. BorgWarner engineers developed a solenoid valve for accumulators that is quiet and allows high flow.
