柴油清净剂改善柴油机有害排放的研究

有关柴油中添加具有清净分散作用的添加剂的研究已成为降低柴油机排放的重要课题。在同一台TY1100柴油机上分别使用试验用空白柴油、加0.15％长城牌LCD级润滑油的柴油样品和加0.15％石油磺酸钙清净分散剂的柴油样品，测定了柴油发动机排放气中各种有害组分的含量、发动机性能和燃烧特性。结果表明，在柴油中添加石油磺酸钙清净分散剂，可以降低柴油机的排放烟度和CO含量，特别是烟度的降低幅度较大。柴油机在高输出功率区域运转时，随着功率的增大，烟度的下降幅度增大。

STUDY ON THE IMPROVEMENT OF FUEL DETERGENT ON HAZARD WASTE EMISSIONS OF DIESEL ENGINE

Using additives in diesel fuel to improve the fuel detergent efficiency becomes one of the key topics to reduce the emissions of diesel engines. Three samples were made: diesel oil as the blank, and diesel oil by adding 0.15% Great wall brand LCD lubricant oil and by adding fuel detergent dispersant 0.15% calcium petroleum sulfonates, respectively. A TY1100 diesel engine was operated to test these samples. Exhaust gas content, engine performance and combustion properties were measured. The results showed that the engine emissions of exhaust smoke and CO content decreased by adding fuel detergent in diesel fuel. Exhaust smoke and CO content decreased with the increase of shaft torque at higher engine loads.
