The fuel adhering to the wall evaporates until it is ignited, whereupon, after the flaaaan front has built up, there is a glaze of evaporation which becomes less and less intense. The position of the ignition source must be different in this internal combustion engine, where the fuel is evaporated and the mixture of combustion air required for ignition occurs. The fuel is drawn off “unäohet aa edge of the fuel bottle after a short stay la Srennraua. This means that the ignition source must have a considerable distance from the slasprltsdüse. Since the evaporation rate does not depend on the type of fuel, fuel that is used for steaming work must be injected later than steaming for a bohwerrer. The timing of the crisis can therefore be alleviated due to a change in the types of force. Furthermore, the place at which the first Terdaapfung occurs also depends on τοη the Terdaapfungsgesohvlndlgkeit and since τοη the type of fuel, for example. dea fuelgealsoh, eo dafi
