Title: (EN) Common rail fuel system for locomotive engine
(ZH) 用于机车发动机的共轨燃料系统
Abstract: front page image
(EN) A common rail fuel injection apparatus ( 1 ) for a multi-bank, diesel locomotive engine ( 10 ). A common rail ( 20,22 ) is disposed proximate each bank ( 20,22 ) of cylinders ( 12 ) of the engine to provide high pressure fuel ( 30 ) to a fuel flow control apparatus ( 14 ) associated with each respective cylinder. A plurality of high-pressure fuel pumps ( 34 ) provides high-pressure fuel to at least one of the common rails. A fluid cross connection ( 38 ) is provided to convey high pressure fuel between the two common rails, thereby providing for the continued delivery of fuel to all cylinders in the event of a failure of one of the high pressure pumps. The high-pressure pumps are motivated by fuel lobes ( 64 ) located on camshaft sections ( 50 a, 50 b, 50 c) adjoined at a gear driven end 58 of the camshaft ( 50 ). Camshaft sections ( 50 d, 50 e, 50 f) adjoined at an idler end ( 60 ) of the camshaft carry lower torque loads than those sections having fuel lobes and may be formed from a lower strength material or may have a smaller shaft diameter.
(ZH)

用于多排、柴油机车发动机(10)的共轨燃料喷射装置(1)。共轨(20,22)被设置靠近发动机汽缸(12)的每一排(20,22),以提供高压燃料(30)到与各自的每个汽缸相联系的燃料流动控制装置(14)。多个高压燃料泵(34)提供高压燃料到至少一个共轨。流体横向连接件(38)被设置,以在两个共轨之间传输高压燃料,由此在一个高压燃料泵故障的情况下提供连续的燃料到所有汽缸。高压燃料泵被位于靠近凸轮轴(50)的齿轮驱动端58的凸轮轴段(50a,50b,50c)上的燃料凸起(64)驱动。靠近凸轮轴的惰轮端(60)的凸轮轴段(50d,50e,50f)传递的扭矩负荷低于具有燃料凸起的那些段传递的扭矩负荷且可由较低强度材料形成或可具有较小轴直径。
