本文对柴油机用新型的蓄压式燃料喷射系统进行了研究,作了若干改进以提高其喷射稳定性。通过在单缸、六缸发动机上进行的性能试验证明,本系统对降低燃油消耗和排气烟色非常有效,特别是低速区的效果尤为显著。 本系统很适用于现在批量生产的发动机,但今后的课题是要达到实用化和喷油泵高压化,以使该系统的性能进一步提高和降低喷油器制造成本。 In this paper, a new type of accumulator fuel injection system for diesel engine has been studied, and some improvements have been made to improve its injection stability. Performance tests on single-cylinder and six-cylinder engines prove that the system is very effective in reducing fuel consumption and exhaust smoke color, especially in the low speed zone. The system is suitable for mass production of the engine now, but the future task is to achieve practical and high pressure injection pump in order to further improve the performance of the system and reduce fuel injector manufacturing costs.
