The invention discloses a constant volume bomb system simulating engine spray combustion. The constant volume bomb system comprises a constant volume bomb body provided with a constant volume bomb inner cavity, a constant volume bomb cylinder cover for sealing the constant volume bomb inner cavity, a pressure sensor, a temperature sensor, a data acquisition card and an image pickup device, wherein the constant volume bomb inner cavity is provided with a front window, a left window, a right window, a gas inlet hole and an exhausting hole, an oil sprayer, a sparking plug and a plurality of heating rods are installed on the constant volume bomb cylinder cover, the pressure sensor is used for detecting the pressure in the constant volume bomb inner cavity, the temperature sensor is used for detecting the temperature in the constant volume bomb inner cavity, the data acquisition card is used for converting signals detected by the pressure sensor and the temperature sensor into signals which can be identified by a computer, and the image pickup device is used for shooting the response situation in the constant volume bomb inner cavity. The constant volume bomb system can simulate the state of the inside of a gas cylinder in a certain moment and can eliminate the influence of gas flowing and heat and mass transfer nonuniformity in the cylinder so as to accurately research the influence on spraying and combustion characteristics of environmental temperature, pressure, oil spraying pressure and other single parameters.
Description
technical field [0001] The invention relates to the technical field of studying engine spray and combustion characteristics, in particular to a constant volume bomb system for simulating engine spray combustion. Background technique [0002] With the energy crisis, environmental pollution and increasingly stringent emission regulations, energy conservation and emission reduction has become a hot issue in the world today. In order to improve fuel economy and reduce emissions, it is necessary to look for excellent, efficient and wide-ranging alternative fuels. , has become a hot research direction in the field of internal combustion engines, and is also an urgent problem to be solved for diesel engines. [0003] In order to find an ideal alternative fuel, it is necessary to study the combustion and spray characteristics of the fuel. The spray of the internal combustion engine is to inject fuel into the combustion chamber through the injector, so that the fuel droplets are ato...
