| 摘 要： | 对车用燃油加热器燃烧室进气孔径(流通面积)、孔的分布、孔的方向等几何参数和进排气压力对加热器燃烧性能的影响进行了试验研究。研究表明,燃烧室进气孔的孔径、孔数、孔的分布及方向等均对燃烧性能影响很大;斜孔所产生的旋转进气,虽具有强化燃气混合、消除死区和回流稳焰的作用,但回流过度会使燃烧室及排温过高;保证进排气系统流动阻力(压力)的一致性,有助于保证加热器性能稳定。

| Abstract: | An experimental study is carried out on the effect of following factors on the combustion performance of a vehicle fuel heater: geometric parameters(the number,diameter,distribution and direction of combustion chamber intake holes) and intake and exhaust pressures.Results show that all the geometric parameters have remarkable effects on combustion performance;the swirl of intake air generated by skew intake holes enhances fuel-air mixing, minimizes dead zone and stabilizes the flame with reverse flow,but the excessive reverse flow can cause overheat in combustion chamber and exhaust;the consistency of flow resistance in intake and exhaust system is conducive to the stability of heater performance. |
