PUMP PLUNGER AND PLUNGER BARREL FOR DIESEL FUEL INJECTION

摘要

Distance of a fuel exhaustion hole (24) and lower reed (32) is decided by rotating plunger barrel (27). Thus, amount of fuel injection is controlled. Distance of upper reed (31) and lower reed (32) becomes longer, the lower reed (31) do not reach to a suction hole (21). The device controls an injection time and amount of a fuel without the injection timer.
