摘要
In a method and apparatus for exhaust temperature elevation for an internal combustion engine with a catalytic converter in which the fuel is direct-injected, the supply of fresh air can be regulated by a throttle device, and the exhaust temperature is determined by a temperature probe or a temperature model, with the internal combustion engine initially operating in stratified mode. The exhaust temperature can be elevated by throttling of the internal combustion engine when an exhaust temperature falls below a threshold value.
