    摘要:

    為解決小型柴油機(jī)在短時(shí)間超負(fù)荷工作時(shí)動(dòng)力不足和冒黑煙的問(wèn)題，設(shè)計(jì)了一種電動(dòng)臨時(shí)增壓系統(tǒng),。該系統(tǒng)由壓氣機(jī),、直流無(wú)刷電動(dòng)機(jī),、車載電源和開關(guān)組成，采用24V車載蓄電池供電,，在發(fā)動(dòng)機(jī)超負(fù)荷工作時(shí)在短時(shí)間內(nèi)進(jìn)行電動(dòng)增壓，蓄電池能量消耗少。臺(tái)架試驗(yàn)表明,，該增壓系統(tǒng)增壓比在1.014～1.020之間時(shí)，柴油機(jī)功率提升5.0%～9.1%,燃油消耗率下降8.5%～14.0%,，增壓效果明顯,，排氣煙度有所改善，壓氣機(jī)的啟動(dòng)瞬態(tài)響應(yīng)時(shí)間在6s之內(nèi),，滿足小型柴油機(jī)克服臨時(shí)動(dòng)力不足的需要,。

    Abstract:

    Small diesel engines have weak dynamic performance and emit black smoke when working overload in a short time. With the aim to solve that problem, a kind of electric temporary turbocharger was designed. The system includes a supercharger driven by DC brushless motor, power supply system on board and a switch. The system is powered by a 24V battery and does not consume too much power due to its short running time. Bench test showed that the supercharging ratio of the electric temporary turbocharger was between 1.014 and 1.020. The power of diesel engine increased by 5.0%~9.1%. The fuel consumption decreased by 8.5%~14.0%. The smoke exhaust problem was improved. Test results indicated that the electric temporary turbocharger could meet requirement when the small diesel engines were weak dynamic performance temporarily.
