The invention provides a multi-component gas high-speed mixing constant volume bomb gas inlet system and a using method thereof. The system comprises four gas cylinders containing gas, a gas inlet pipeline, a pressure sensor, a hot-air blower, a first safety valve, a gas inlet valve, a spark plug, a fuel injector and a second safety valve; the four gas cylinders are symmetrically distributed on the two sides of the gas inlet pipeline, the gas inlet pipeline is connected with the combustion chamber, a pressure sensor, an air heater, a first safety valve and a gas inlet valve are sequentially arranged on the gas inlet pipeline, and a spark plug, a pressure sensor, a plurality of thermocouples, a fuel injector and a second safety valve are arranged on the combustion chamber. The invention provides a constant volume bomb gas inlet system for high-speed mixing of multi-component gas and a use method thereof in order to achieve the purposes of reducing the risk of experiments and the high requirement of equipment as much as possible and guaranteeing accurate control and sufficient mixing of all gas components. According to the constant volume bomb, the combined design of a special air inlet / mixing pipeline, an air inlet valve and a tangential air inlet is used for synchronously achieving air inlet and premixing.
Description
technical field [0001] The invention relates to a constant-volume bomb intake system for high-speed mixing of multi-component gases and a method for using the same, belonging to the technical field of heat engines. Background technique [0002] The combustion quality of the engine is one of the important factors affecting the combustion and emission performance of the engine, and the quality of fuel atomization is the key factor. High-quality fuel atomization is of great significance to improve the performance of the engine, especially for marine diesel engines. If the fuel Poor atomization quality will cause great damage to the equipment, and the working environment of the marine diesel engine also makes the maintenance of the equipment extremely difficult. A necessary prerequisite for platooning and developing new engines. [0003] Constant volume bomb is an effective experimental device for studying fuel spray and combustion, and it is a good carrier between theoretical ...
