Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments do not limit the present invention in any way.

[0033] Such as figure 1 As shown, a small fast compressor based on electromagnetic control proposed by the present invention includes a main combustion chamber system 1 , a power system 2 and an electromagnetic control circuit 3 .

[0034] Such as figure 1 and figure 2 As shown, the main combustion chamber system 1 includes a combustion chamber gland 4, a cylinder and a compression piston 8, and the cylinder block 11 of the cylinder is composed of an outer sleeve 5 and an inner sleeve 6 nested in each other. There is a radial gap between the sleeve 5 and the inner sleeve 6, and the gap is 5±0.5mm, thereby forming an annular space; one end of the outer sleeve 5 is provided with an oil inlet hole 51, The other end of the outer sleeve is provided with an oil outlet ho...

Abstract

The invention discloses a small fast compressor based on electromagnetic control, which is mainly composed of a main combustion chamber system, a power system and an electromagnetic control circuit. The main combustion chamber system consists of a gland and a two-layer sleeve, and heat transfer oil flows through the gap between the two sleeves to heat the combustion chamber. The power system includes a cylinder block, a power cylinder gland, a brake ring, a power piston, a drive ring and a laser distance sensor. The laser ranging sensor measures the distance through the center hole of the power cylinder gland, and thereby realizes the control of the compression process. The electromagnetic control circuit includes a DC power supply, a sliding rheostat and five switches. The DC power supply provides current; the sliding rheostat is used to adjust the circuit current, thereby changing the magnitude of the electromagnetic force between the coils; the three switches are used as on-off switches for the circuit, and the other two Together as a switch, they are responsible for changing the direction of the current flow in the coil, thereby changing the direction of the electromagnetic force. The fast compressor of the present invention has a simpler and more compact structure and a more efficient working process.

Description

technical field [0001] The invention is a small fast compressor based on electromagnetic control, which relates to the technical field of thermal energy and power engineering testing, in particular to a fast compression experiment for the study of the spontaneous combustion characteristics of hydrocarbon fuels such as gasoline, diesel and aviation kerosene and the combustion process of internal combustion engines device. Background technique [0002] The fast compressor is a basic experimental platform for simulating the working process of internal combustion engines and the spontaneous combustion characteristics of gasoline, diesel, aviation kerosene and other hydrocarbon fuels. The fast compressor pushes the compression piston with the help of external force to instantly compress the pre-mixed gas in the combustion chamber to a thermodynamic state of high temperature and high pressure, and then uses the braking system to stop the compression piston, so that the pre-mixed g...
