Abstract (en)
[origin: WO8801019A1] The high-pressure end of fuel injection pumps and injection nozzles of diesel engines stands only cyclically under high pressure. During most of the time, the high-pressure line (4) is relieved from pressure. During this time, a second fuel can be introduced in the high-pressure end via an additional fitting (7), inasmuch as the fuel already contained therein yields without opening the nozzle (6, 3, 12). The following high-pressure cycles gradually convey the second fuel to the nozzle opening.
