Engine: Description and Operation

Introduction, 6 cylinder engines





General
A large number of components are new compared to the engines in the S/V70 and S/V90. 6-cylinder engine: approximately 90% of the main components are new. The modifications result in reduced fuel consumption, increased performance and approximately a 7-8% reduction in CO2 emissions.
The S80 fulfills the requirement for emissions according to TLEV.
The six cylinder engines have double catalytic converters, each catalytic converter consists of a monolith insert and a ceramic insert.
The front heated oxygen sensors (HO2S) are of the linear type. The linear heated oxygen sensors (HO2S) means that the emissions can be controlled more accurately at cold starts and under high loads.
