Study on Leakage and Seal of High-Pressure Fuel Pump of Common Rail Fuel System 共轨燃油系统高压油泵泄漏与密封的研究
In the light of existing thorny problem of producing higher fuel injection pressure due to clearance leakage between plunger and plunger sleeve of common fuel injection system, some refinements into plunger pinion are introduced by making use of techniques named flexible and variable cross section plunger. 针对普通燃油泵因燃油渗漏而难以建立高燃油压力的问题,利用柔性可变截面控制技术,对燃油泵柱塞偶件进行了改进设计研究。
Low viscosity-liquefied fuels leakage from the plunger pinion clearance of fuel pumps 低粘度液化燃油在油泵偶件环隙中泄漏的研究
An Analysis on the Leakage in Precision Pair of High Pressure Common Rail Fuel Injector 高压共轨喷油器精密偶件的泄漏分析
On-line test for leakage and venting of the car's fuel system 整车燃油系统密封性通气性的在线检测
In the domestic, The equipments for testing leakage and venting of the fuel system are different, manufactories design and make the expert equipments for testing their own automobile. 国内现有的对汽车燃油系统进行气密性和通气性检测的设备还没有统一的标准,各大汽车生产商都是根据自己的实际情况设计制造了专用设备。
Leakage Test of Fuel Spray Nozzle in Diesel Engine Based on Computer Image Identity 基于计算机图像识别的柴油机喷油嘴渗漏检测方法
This sensor structure can be applied to detecting hydrogen leakage of commercial and military vehicles with hydrogen as fuel. 这种传感器结构将用于监测氢气作燃料的商用和军用机车的氢气泄漏。
The analysis of the detecting results of some light duty tractors show that most tractors, power, specific fuel consumption, pressure in the cylinder, fuel-feed time and the leakage of the fuel, cooling water and lubrication are not qualified. 对部分小型拖拉机的技术状态的检测结果进行了统计分析,柴油机的功率、油耗、转速、汽缸压力、供油时间等不合格率较高,三漏现象特别突出。
When a conventional leakage occurs in the limited space, because of the door and window ventilation, it will lead indoor gas concentration distribution to a non-uniform change process. In the non-uniform fuel concentration field, the flammable area is limited. 当气体燃料在受限空间内发生常规泄漏量的泄漏时,由于室内通风条件的存在,这必然将导致室内燃气的浓度分布是不均匀的,且在室内可燃区域所占体积有限。
A typical fuel leakage fire is pool fire with a certain fuel thickness, as well as boilover burning of fuel spilled on water. 典型的燃油泄漏火灾是具有一定厚度的油池火,以及可能引发喷溅现象的垫水池火。
