Research on Test System for Multiple Spray Characteristics of Fuel Engine Nozzles
The article focuses on the research of measurement techniques for fuel injector spray characteris-tics,analyzing two commonly used devices in China:Phase Doppler Particle Analyzer(PDPA)and Particle Im-age Velocimetry(PIV).Addressing the issue of existing devices often being limited to measuring partial spray characteristic parameters,presents a multifunctional experimental system scheme for fuel injector spray charac-teristics based on PDPA.The system enables comprehensive measurement of spray characteristics(including spray cone angle,penetration distance,droplet size distribution,concentration distribution,and velocity distri-bution),as well as tests for circumferential and radial non-uniformity of the spray.It provides a reference for the measurement technology of fuel injector spray characteristics for internal combustion engines.
