N2 - 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 emitted gas). The emission results were explained by the experimental data and the formation mechanism of the above 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 outside of the cylinder, the CHN4 emission level may be realized.
