Abstract

The invention discloses a fuel injection quantity electrical signal acquisition system and method based on a Zeuch pressure magnetic method. The system comprises a measurement module, a fuel injectorpressurization module, a square-cavity pressurization module and a signal post-processing module. The fuel injector pressurization module and the square-cavity pressurization module are used for loading the initial injection pressure and the square-cavity back pressure; after a fuel injection process is completed, the measurement module captures a pressure signal variation curve in the square-cavity; and a pressure signal curve can be reverted to an actual fuel injection rate by the signal post-processing module after the operations of filtering, differentiation, calibration and the like are performed. The invention designs and processes a fuel injection rate measuring instrument, and the measuring instrument can effectively detect a multi-stage injection process, and is high in repeatability, convenient to carry, and low in noise and good in seismic performance during use.

Description

technical field [0001] The invention belongs to the field of fuel spray diagnosis, and in particular relates to a fuel injection rate measurement system and method based on a Zeuch piezomagnetic method. Background technique [0002] High-energy-density liquid fuels (gasoline, kerosene, etc.) are the main fuels for automobile engines and aero-engines. The spray process is a process in which liquid-phase fuel interacts with gas and breaks into droplets. The quality of fuel atomization is crucial to the formation of efficient A low-polluting combustion process has a crucial impact. The fuel demand and demand rate of the engine are different under different working conditions. Therefore, accurate measurement of the fuel injection rate curve of the injector under different conditions has an important guiding role in optimizing the combustion process. At the same time, the fuel injection rate curve is the engine calculation Important initial conditions for the simulation. [000...
