Abstract

The invention provides a hot-blowing adjustable nozzle which comprises a nozzle body and a nozzle core movably arranged in the nozzle body. The nozzle body comprises a nozzle casing and an installation portion which is used for installing the nozzle core and arranged in the nozzle casing; the inner wall surface of the nozzle casing and the outer wall surface of the installation portion form a fuel passage; and a nozzle opening communicated with the fuel passage is arranged in the nozzle casing. According to the hot-blowing adjustable nozzle, the nozzle core is movably arranged in the nozzle body, and a taper angle of a taper body is slightly smaller than a taper angle of an inner taper cavity, so that the hot-blowing adjustable nozzle can meet environment requirements of different fuel supplies and pressure, and fuel sprays sprayed out can be guaranteed to be uniform; an inverted taper body enable the fuel to be further impacted into particles to form fuel sprays, and the atomization quality is improved; and an adjustable opening is convenient for pushing the nozzle core to move axially, and various fuel supply environment requirements are met.

Description

technical field [0001] The invention relates to the field of superchargers, in particular, to a heat-blow adjustable nozzle Background technique [0002] Existing internal combustion engines all need to adopt supercharging technology, generally, a supercharger is installed in the internal combustion engine. The development of new varieties of superchargers and the improvement of supercharger performance are inseparable from the test bench, and the fuel injector is a compressor performance test bench, a turbine performance test bench, an overspeed test bench, a containment test bench and a self-circulation test bench. necessary facilities. [0003] In order to increase the turbine inlet energy, the existing test bench mainly adopts the following two measures: one is to increase the pressure of the air source; the other is to increase the temperature of the working medium. [0004] One is to increase the pressure of the air source. However, increasing the pressure of the...
