The invention discloses a rapid detection method for a piston cooling nozzle (PCN) performance experiment. The method comprises steps that quantitative oil supply for a PCN is carried out according to a set air exhaust oil supply flow value, and air in an oil supply pipeline and the PCN is exhausted; quantitative oil supply for the PCN is carried out according to a set closure pressure detection oil supply flow, value and closure pressure is detected; oil supply for the PCN is stopped; quantitative oil supply for the PCN is carried out according to a set start pressure detection oil supply flow value, and start pressure is detected; quantitative oil supply for the PCN is sequentially carried out according to the multiple flow values, and oil drainage amount and shooting ability are detected; quantitative oil supply for the PCN is carried out according to a set leakage flow detection oil supply flow upper limit value, and the leakage flow is detected; oil supply for the PCN is stopped, and PCN detection is ended. The method is advantaged in that PCN performance detection is realized through employing a quantitative oil supply flow adjustment experiment test mode, detection efficiency is substantially improved, and the rapid detection speed can be 6.5s for each piece.
Description
technical field [0001] The invention relates to a detection method for performance experiments of piston cooling nozzles, in particular to a rapid detection method for performance experiments of piston cooling nozzles based on quantitative oil supply flow. Background technique [0002] Piston cooling nozzle or PCN (hereafter referred to as PCN), as an important part of the automobile engine, its performance has an extremely important effect on the lubrication and cooling effect of the engine's moving piston. [0003] The switch characteristics and flow characteristics tests of PCN are factory inspection items, which require 100% full inspection and testing of all manufactured products. The specifications and models of PCN are different, and the technical index requirements are different. [0004] The technical indicator parameters that need to be tested include: [0005] Opening pressure: The oil supply pressure value when the flow rate rises from low to high to the specif...
