The Saab Combustion Control (SCC) system is a new engine control system
developed to lower fuel consumption while radically reducing exhaust
emissions, without impairing engine performance. By mixing a large volume of
exhaust gases into the combustion process, Saab's fuel consumption can be
reduced by up to 10 percent, and exhaust emissions lowered enough to comply
with the California Ultra Low Emission Vehicle 2 (ULEV2) requirements, set to
take effect in 2005. Compared to today's Saab engines with equivalent
performance, this will reduce the carbon monoxide and hydrocarbon emissions
by almost half, and will cut the nitrogen oxide emissions by 75 percent. The
SCC system will be launched in the next generation of Saab cars.
