摘要

The device for the control of an internal combustion engine which can be run on a first and a second fuel, has a selector device (1) which determines which fuel is advantageous for a possible operating state of the engine with regard to exhaust gas emissions, and which initiates running of the engine with the corresponding fuel. A gaseous fuel is used as the first fuel and a liquid fuel is used as the second fuel. The gaseous fuel may be a compressed natural gas or liquefied gas, and the liquid fuel may be petrol or diesel oil. An independent claim is included for a method for the control of an internal combustion engine by application of the aforesaid device.
