Abstract

A combustion engine with electromagnetic controlled fuel injection apparatus is provided with a water injection for short duration during load increases in order to prevent thermal damage. For this reason there are provided, in addition to the fuel injection valves, also water injection valves of the same construction and size, whereby all injection valves are operated by a common electrical control device one after the other in a cycling sequence.
