The invention discloses a special ultra-long-distance signal transmission device in a narrow space. The special ultra-long-distance signal transmission device in the narrow space comprises a copper rod, a glass fiber tube, a heat-shrinkable tube, an oil sprayer body, a gasket and an electromagnetic valve. The special ultra-long-distance signal transmission device in the narrow space has the beneficial effects that the copper rod is a metal rod with the diameter of 1 mm, and the long and thin copper rod is used as a signal transmission medium to realize long-distance signal transmission; the glass fiber tube is wrapped around the copper rod as a heat insulation layer and has high temperature resistance, so that the glass fiber tube is used to ensure that no contact exists and high temperature of greater than 600 DEG C is resisted; the heat-shrinkable tube is fixed in the oil sprayer body through anaerobic glue to be prevented from moving in the oil sprayer body, so that the long and thin copper rod and the glass fiber tube are fixed and limited; and due to the fact that the bottom end of the copper rod is inserted into a hole of the electromagnetic valve, the oil sprayer body is detachably connected with the electromagnetic valve, so that the assembly and disassembly are easy when the device is maintained, and the use is convenient, stable and safe.
Description
Technical field [0001] The invention relates to a transmission signal device, in particular to a special narrow space ultra-long-distance transmission signal device, which belongs to a component of a common rail injector of a diesel engine. Background technique [0002] Diesel engine common rail injector is a precision device with very high processing accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The fuel injector receives the fuel injection pulse signal sent by the ECU to accurately control the fuel injection volume; the spray characteristics of the fuel injector include atomization particle size, oil mist distribution, fuel beam direction, range and diffusion cone angle. These characteristics should meet the requirements of the diesel engine combustion system, so that the mixture formation and combustion are perfect, and higher power and thermal efficiency are obtained. [0003] In the...
