摘要： An injector for directly injecting fuel into a cylinder of an internal combustion engine having a socket. The injector is provided with a nozzle insertable into the socket. An annular gap is defined between the nozzle and the socket when the nozzle is received in the socket. A first seal groove, formed in the nozzle, receives a first gas seal that seals the annular gap. A second seal groove, formed in the nozzle, receives a second gas seal that seals the annular gap. The second seal groove is formed closer to the distal end of the nozzle than the first seal groove. The depth of the second seal groove is greater than that of the first seal groove. This structure prevents the formation of deposits and maintains the sealing capability of the gas seals without lowering installation and maintenance efficiency.
