Abstract
A very compact and inexpensive fuel injection device for auto-ignited internal combustion engines can be mounted on existing internal combustion engines to replace conventional fuel injection devices. The fuel injection device has one or more high-pressure pumps (10) that feed fuel into a supply tank (11) from which the fuel may be supplied through proportioning valves (16) to injection valves (15, 15'). The pressure in supply tank (11) is maintained by an automatic control system for the high-pressure pumps (10), the outputs of which are controlled by a control rod (13) that adjusts a plunger (18) of the high-pressure pumps (10) provided with a slanting edge (17).
