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。
