Porsche The Cayman 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 accomplished by the use of fuel-efficient technologies such as auto start/stop, thermal management, electrical system recuperation, direct fuel injection, VarioCam Plus and, in conjunction with optional PDK, coasting mode.

The newly developed catalytic converters also provide efficient emission control, while the stereo Lambda control circuitry manages and monitors each cylinder bank separately. For each exhaust tract, oxygen 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.
