Abstract

In a method for generating an internal combustion engine configured to run on both a gas fuel and a liquid fuel, the shutoff valve of the gas injection system is initially closed, the engine is then operated with the liquid fuel, and subsequently all gas injection valves of the gas injection system are opened in a predefined pattern while the shutoff valve is still closed.
