Abstract

The invention discloses an apparatus and method for measuring air flow of an oil spray nozzle of an indirect-injection diesel engine. The apparatus herein is provided with a digital display dial gauge on a top portion of an oil sprayer assembly. The bottom portion of the oil sprayer assembly is provided with a depthometer. The oil spray nozzle is installed on the oil sprayer assembly. The oil spray nozzle is communicated with an air flow meter via air delivery pipeline. The air flow meter is communicated with a vacuum pump via a pressure-regulating tank. Air delivery pipeline which makes the air flow meter and the pressure-regulating tank communicated is provided with an adjustable vacuum pressure meter thereon. The method herein comprises: a stage of installing the oil spray nozzle to be measured; a stage of setting measurement conditions and parameters; and a stage of outputting a tested result after the measurement. The apparatus and method have the beneficial effects of: the apparatus and the method are used for measuring the air flow of the oil spray nozzle of the indirect-injection diesel engine, and can rapidly and accurately detect associated indexes of a diesel product with a low testing cost, and are markedly significant in regulating the use quality of diesel in the fuel market and refraining the emission of the diesel vehicles.

Description

technical field [0001] The invention relates to a measuring device and method, in particular to an air flow measuring device and method for an injector nozzle of an intermittent diesel engine, belonging to the technical field of measuring devices. Background technique [0002] Automobile exhaust emissions are one of the important causes of smog. More and more serious smog has seriously affected people's health. [0003] PM2.5 mainly refers to the emissions from automobile engines, and the emissions from large vehicle engines that use diesel are the main emission groups. In the State Council’s Air Pollution Prevention and Control Action Plan Notice, there are special requirements for the application of oil products: to improve the quality of my country’s vehicle fuel, to speed up the upgrading of oil refining enterprises, and to provide the country with diesel and gasoline that meet the standards. Strengthen oil product quality supervision and inspection, and severely crack...
