Electromagnetically controlled fuel injector with integrated ignition device - pumps fuel into cylinder by pressure wave from sliding disc impelled against opposition of restoring spring

摘要

A storage capacitor is discharged through a coil (2) in the pumping space surrounding an insulator (9) within which the fuel supply channel (11) is opened and closed by a control element (10. The space is previously filled via two diaphragm valves (12) with fuel, to which kinetic energy is transferred from the disc (3) lifted from its seating. The spark is struck between a central electrode (7) and a threaded portion (5) of the housing (1). ADVANTAGE - Fuel supply, injection and ignition are combined in one unit which avoids losses by injecting only after cylinder scavenging with pure air.
