New Bosch mild hybrid system aims to cut NOx

0

The technology uses a 48V boost recuperation system to reduce nitrogen oxide emissions at the point of combustion by supporting the IC motor with electric boosts. Deploying the energy under acceleration and at high speeds will cut NOx emissions by up to 80% and CO2 by up to 15% in everyday compact vehicles, says Bosch.

The system is integrated into a car’s design from the initial stages, recovering energy under braking that is then stored in the 0.25kWh lithium-ion battery. When the energy is required it’s sent back to the boost recuperation system, which functions as an electric motor. Bosch says that the setup could be most beneficial to small turbocharged engines, adding useful torque.

   

Bosch UK president, Steffen Hoffmann, said, “The new boost recuperation system will enable drivers to enjoy extra torque of 150Nm while also protecting the environment. Now revving the engine means you can enjoy your car without the harmful emissions.”

The German firm expects around four million vehicles worldwide could be fitted with its new system by 2020, filling what it sees as a gap between stop/start systems and hybrid drives. Diesel engine manufacturers are under pressure to reduce fine particulate emissions in Europe ahead of the introduction of the Euro 6 directive in September.
