Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] combine Figure 1 to Figure 4 , the present invention includes a fuel injector mounting base 2, a fuel injector gland 1 and bolts 3, 4; the fuel injector mounting base is an integral structure, a fuel injector for fixed volume Homemade parts such as image 3 , 4 As shown, the fuel injector installation base 2 is divided into upper, middle and lower layers, which are respectively cylinders with different diameters and penetrate the middle up and down and have a through hole for installing the fuel injector. The inner cavity profile of the through hole It is consistent with the characteristics of the outer wall of the injector. At the same time, the cylinder at the bottom of the injector installation base is well fitted in the installation hole of the injector of the constant volume bomb. Movement under the influence of high-f...

Abstract

The invention provides a sealing pressure-resistant device mounted with a constant-volume-bomb oil atomizer. The sealing pressure-resistant device comprises an oil atomizer base and an oil atomizer gland, the oil atomizer base is divided into upper, middle and lower portions and is through from top to bottom, the inside of the oil atomizer base is hollowed for mounting the oil atomizer, an inner cavity is matched with the oil atomizer to well limit radial movement of the same, the oil atomizer gland is a cover with a U-shaped opening, connected with the oil atomizer base through a bolt and embedded with the oil atomizer through the U-shaped opening to limit rotation of the oil atomizer, and the oil atomizer is fixed through two fixing measures of the oil atomizer base and the oil atomizer gland. The oil atomizer base is provided with a sealing device, so that sealing between the oil atomizer and a constant volume bomb body can be guaranteed. The sealing pressure-resistant device is simple in structure, convenient to mount, adaptable to all types of mounting devices, good in fixing effect, capable of guaranteeing position of the oil atomizer to be unchanged under high-frequency vibration and guaranteeing sealability and suitable for specific requirements of constant volume bomb atomization burning experiments.

Description

technical field [0001] The invention relates to a sealing pressure-resistant device for installing a constant-volume bomb fuel injector, and belongs to the technical field of constant-volume bomb sealing installation. Background technique [0002] The combustion performance of a diesel engine directly affects the power, economy and emission of the diesel engine. In order to better improve the combustion performance of diesel engines, it is very necessary to explore the combustion process and characteristics of diesel engines from the root. However, in practice, the combustion process of fuel oil is complicated and there are too many influencing factors, which have caused great difficulties in the study of diesel engine combustion theory. The constant-volume incendiary bomb, which has a simple structure and can accurately control various thermodynamic parameters, is an important tool for basic research on diesel engine combustion theory. The sealing and pressure-resistant de...
