Exhaust emission control Boxster S

Porsche Boxster S - Exhaust emission control

Exhaust emission control

Vehicles manufactured by Porsche demonstrate that even high-performance sports cars can achieve moderate fuel consumption and exhaust emission values in their respective category.

This is achieved, on the one hand, by the use of fuel-efficient technologies such as direct fuel injection, VarioCam Plus, thermal management, electrical system recuperation, auto start/stop and, in conjunction with optional Porsche Doppelkupplung (PDK), coasting mode.

On the other hand, newly developed catalytic converters provide efficient emission control.

While the stereo Lambda control circuitry controls and monitors each cylinder bank separately. For each exhaust tract, Lambda sensors, together with the engine electronics and injectors, regulate the composition of the exhaust gas, while another Lambda sensor on each cylinder bank monitors pollutant conversion in the respective catalytic converter.
