The investigation has declared that the fuel injection with BQ fuel pump had higher injection pressure, bigger fuel supply rate and shouter fuel supply duration, which would cause the fuel injection quantity and the fule-air mixture to increase during ignition delay period, the pre-mixed combustion to become acutely, and finally result in increased power levels of noise.

研究表明，装配BQ喷油泵，喷油系统的喷油压力较高，供油速率较大和供油持续时间缩短，使得滞燃期的喷油量增加，滞燃期内形成的可燃混合较多，预混燃烧剧烈，导致整机噪声声功率级增加。

When diesel/CNG dual-fuel turbocharge intercooling engine D6114 runs in dual-fuel mode, only diesel fuel is supplied when starting and idling, and when engine speed is beyond the preset value,electronic control system send out command to limit diesel fuel injection amount,and natural gas begin to enter into cylinder through mixer to take part in burning, at this time small a mount of diesel fuel shall play mainly a role of ignition,and engine load is changed by altering natural gas supply amount.

D6114柴油/CNG双燃料增压中冷发动机当以双燃料方式工作时，发动机起动和怠速只燃用柴油；当转速超过某设定值，电控系统发出指令限制柴油的喷油量，天然气经混合器进入气缸参与燃烧，此时少量柴油供给主要起引燃作用，发动机负荷变化则通过改变天然气供给量的大小来实现。

When the swirl variable device is part-opened, because swirl has some effect on the second injection, second injection timing has distinctly effect on fuel consumption, and the fuel consumption change fluctuantly with twice injection timing. When the tumble variable device is adopted, second injection timing also has effect on fuel consumption, but there is only one point that the fuel consumption is lowest. When the load is bigger, the second injection point where the fuel consumption is lowest is earlier than the smaller load.

在可变涡流结构中，当阀片处于非全开状态时，由于涡流运动对二次喷油的作用，二次喷油正时对发动机的比油耗存在明显影响，发动机比油耗随喷油正时改变呈较明显的波动状；在可变滚流结构中，二次喷油正时对发动机比油耗同样存在影响，但最低油耗点只有一个，当负荷较大时，最低比油耗所对应的喷油正时要更早一些。
