Diesel engine in use, fuel injector nozzle will occur wear and carbon accumulation, resulting in engine work economic index and power index deterioration. The technical conditions formulated by the manufacturer have certain requirements for the effective flow spot section of the nozzle. These requirements are checked on a constant pressure test bench using a pneumatic instrument (rotor flowmeter >.
The rotameter is not widely used in the depot because its accuracy depends on the stability of the wind pressure, the presence of water and shunt in the rotameter, and the cleanliness of the suona. The examination of suona on a constant pressure test table requires specialized equipment and is inefficient.
A hydraulic method for checking the effective flow section of the nozzle and nozzle of a diesel engine in a single injection process was studied by the Belarusian Academy of Railway Transportation Engineering. The essence of this method is to establish the initial pressure in the storage tank with a certain volume, connect the storage tank with the inspected nozzle (sprayer) in a given period of time (0.0 4 ~ 0.016s) by using the injection device, record the residual pressure of the storage tank, and determine the effective flow section of the nozzle according to its value. The residual pressure in the tank should decrease with the increase in the effective flow rate of the jet holes of the nozzles; for different nozzles, the amount of time the fuel flows through them is equal.
In the article "Repairing the Diesel Injector Nozzle by a New Process" (3TT 1986, N0 7), it is introduced that the working performance of the nozzle can be restored by repairing the needle valve lock round. This method is a shortened repair cycle characterized by a low amount of labor.
However, the nozzle sent for repair (about 40% of the nozzle) often has a large number of defects in the nozzle body locking circle dimension. In these cases, in addition to repairing the needle valve locking cone, the nozzle body needs to be repaired. Sometimes the rise of the needle valve must be adjusted.
