摘要
Abstract
For the purpose of optimizing the emission characteristics of a double swirl combustion chamber with a throat size of 96 mm, tests were carried out for selecting a proper spray angle. The spay angles of 155° and 160° were applied for testing an oil sprayer. The data from the tests of the general performance and partial load property showed that, when the spay angle is 155°, the concentration of the particle is lower than that at 160° by 0.02~0. 27 mg/m3, and the NOx concentration is higher by 14×10-6~70×10-6(10-6 of the ratio between NOx and the total e-mitted gas) . The emission results were explained by the experimental data and the formation mechanism of the a-bove emission characteristics was explained by the simulation analysis. The research shows that the emission of the particle may be effectively reduced by the application of a spray angle of 155°;in addition, if NOx is processed out-side of the cylinder, the CHN4 emission level may be realized.关键词
