Robert Bosch公司最近向市场推出了一种高速柴油机用新型PLD燃油喷射系统。PLD为德文Pumpe-Leitung-Duse的缩写,其意为该系统由独立的高压筒形燃油泵(Pumpe)、短的高压油管(Leitung)和普通的喷油嘴(Duse)组成。 PLD系统现已用于Deutz Motor公司的新型水冷FM1012(27～123kW)和1013(93～190kW)高速柴油机上,并可提供电子和机械控制两种类型的产品。 这种新型喷油系统的最高喷射压力可达150MPa;由于喷油泵由发动机凸轮轴直接促动,因此它具有高的机械稳定性;它采用了较短的高压油管,故而具有较高的液压稳定性。特别是在采用普通
Robert Bosch recently introduced to the market a new PLD fuel injection system for high-speed diesel engines. The PLD is an acronym for the German Pumpe-Leitung-Duse, which means that the system consists of a separate Pumpe, a short high-pressure fuel line and an ordinary Duse. The PLD system is now available on Deutz Motor’s new water-cooled FM1012 (27 to 123 kW) and 1013 (93 to 190 kW) high-speed diesel engines and offers both electronic and mechanical control. The new injection system has a maximum injection pressure of up to 150 MPa; it has high mechanical stability due to its direct actuation by the engine camshaft; it uses a shorter high-pressure tubing and therefore has a higher hydraulic stability Sex. Especially when using ordinary
