ABSTRACT:
An injector arrangement is disclosed in which liquid fuel in variable quantities is received within an injector chamber in a continuous flow. The admitted fuel is stored and intermixed with hot high-pressure burnt gases retained from previous combustion period for timed injection during or near the end of the compression stroke. During the intermixing period in the injector chamber preheated liquid fuel is partly or fully vaporized. Cam operated linkage is set up to hold over the injector in an open position until hot high-pressure burnt gases of combustion can re-enter the injector chamber for the next fuel charge preparation. A variable delivery liquid fuel pump provides for fuel quantity regulation according to torque output requirements. A tiny capillary passage at the entrance to the injector chamber provides the necessary flow restriction to obtain continuous fuel flow. Disclosed are two injectors of slightly different construction eliminating the need for return springs.
