Vehicle with catalytic converter, comprises arrangement for switching off engine temporarily when temperature threshold value has been reached

摘要

The vehicle has an internal combustion engine working with jet guided direct fuel injection and stratified charge. When an idle state is detected and in particular the temperature in the catalytic converter has exceeded the predetermined threshold value the engine is temporarily switched off. The catalytic converter is not cooled down unnecessarily by cold gas. The heating power present is distributed within the catalytic converter instead and increases the heat further.
