Abstract

The invention provides an oil injector adjustable adaptive device based on a constant-volume bomb, and belongs to the technical field of optical visualization testing of constant-volume bombs. The problem of adaptation between the oil sprayers of various sizes and constant volume bomb equipment is solved. The device comprises a fuel injector adjustable upper adapter, a fuel injector adjustable lower adapter, a centering clamping sliding block, a detachable adjusting knob column and a half-moon plate, the detachable adjusting knob column rotates to drive the fuel injector adjustable upper adapter to rotate, and therefore the centering clamping sliding block is driven to move in a centering clamping sliding block sliding rail towards the fuel injector. The fuel injector can be centered and clamped, the half-moon plate is arranged above the adjustable upper adapter of the fuel injector, the half-moon plate is used for positioning the fuel injector, and the half-moon plate is fixed to the constant volume bomb. The device is suitable for oil sprayers of various sizes, an adaptive device does not need to be customized for one oil sprayer, the blank in the prior art is filled, the test cost is saved, and the device is easy to operate and convenient to disassemble.

Description

technical field [0001] The invention belongs to the technical field of optical visualization testing of constant-volume bombs, and in particular relates to an adjustable fitting device for fuel injectors based on constant-volume bombs. Background technique [0002] With the approach of the energy crisis and the increasingly perfect emission regulations, the performance requirements of the engine such as economy and emission have also gradually improved. Among them, the research on the internal basic mechanism of the engine has become more and more important, and the fuel spray characteristics of the engine are the influence. One of the most important factors of engine performance, and the spray characteristics of the injector directly affect the internal mixing and combustion of the engine and other working processes, which in turn affects the engine's economy, stability and emissions indicators. [0003] The combustion process of the engine includes fuel injection, atomizat...
