摘要
针对柴油机缸内燃烧压力振荡对发动机工作过程产生的重要影响,试验研究和理论分析转速、负荷、喷油提前角等对直喷式柴油机燃烧压力振荡的影响 研究结果表明:随着运行参数的变化,柴油机的滞燃期发生了变化,从而影响了滞燃期内喷入气缸的燃油量,严格控制滞燃期可以有效地降低燃烧压力振荡强度 缸内燃烧压力振荡的研究。
The impact of rev, load and injection timing on combustion pressure oscillation is studied in detail for vehicle diesel engines. Results show that delay period is the fundamental factor in generating pressure oscillation. Rev, load and injection timing control the delay period and the quality of fuel injected in this period. By controlling delay period accurately we can reduce combustion pressure oscillation effectively.
