Abstract

A fuel injection system, especially for Diesel engines using relatively hard-to-ignite fuels. The system includes a low pressure pump for delivering an easily ignitable fuel into a pre-storage chamber within a pressure divider. A high-pressure pump delivers the main fuel component and also applies pressure to an expulsion piston which expels the prestored igniter fuel. A number of embodiments is presented.
