阐述了CA6110ZLA3型车用柴油机排放控制方法;提出了具体的技术措施;通过提高喷油压力,改善喷油速率及喷 雾质量,延迟喷油定时,优化匹配涡轮增压器及改进燃烧室形状等技术进行优化匹配试验,NOx和PM排放值分别由 7.8g/(kW·h)和0.36g/(kW·h)降到6.8g/(kW·h)和0.14g/(kW·h),使该型柴油机排放达到了欧Ⅱ标准。
The control method of CA6110ZLA3 diesel engine is expounded. Specific technical measures are put forward. By improving the injection pressure, improving the injection rate and spray quality, delaying the injection timing, optimizing the matching turbocharger and improving the shape of the combustion chamber Optimized matching test was conducted to reduce NOx and PM emissions from 7.8 g / (kW · h) and 0.36 g / (kW · h) to 6.8 g / (kW · h) and 0.14 g / (kW · h), respectively This type of diesel engine has reached Euro Ⅱ standard.
