Title: METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE AND DEVICE FOR PERFORMING THE METHOD
Abstract:
The invention relates to a method for operating an internal combustion engine (10), wherein a gaseous fuel, in particular methane, is mixed with air and the fuel-air mixture is burned in a combustion chamber (1) of the internal combustion engine (10), wherein the gaseous fuel is blown in via a gas valve (2) and the air supply is controlled by means of a throttle valve (3). According to the invention, the air amount is increased in accordance with the operating state of the internal combustion engine (10), in particular in the event of a load change, in that air is additionally blown in via a separately controllable air valve (4). The invention further relates to a device for performing the method.
