    摘要： An internal combustion engine comprises one or more pairs of first and second cylinders, the first cylinder having a larger swept volume than the second cylinder and respective first and second pistons reciprocable in the cylinders. The second piston has a drive stem and divides the second cylinder into a first volume containing the drive stem of the second piston and a second volume between the two pistons. An air inlet and an exhaust outlet are provided for the first cylinder. A common combustion space is formed between the pistons when the pistons are substantially at their inner dead center positions, the combustion space comprising the second volume. A transfer means enables gas flow between the first volume and the combustion space towards the end of the compression stroke while an inhibiting means inhibits the movement of fuel/air mixture from the first volume into the second volume until towards the end of the compression stroke of the second piston. A fuel injector provides fuel to the first volume during the induction stroke of the second piston. The engine also has drive means for driving the second piston, the drive means including means for maintaining the second piston substantially at its inner dead center position during at least a portion of the expansion stroke of the first piston.

    摘要： A cooling system for an engine having a plurality of cylinder bores which are arranged along a longitudinal axis. First and second coolant passages continuously extend along the periphery of the bores on each side of the axis, extending from the bore arranged in one end of the engine to the bore arranged in another end of the engine. The first and the second passages are connected to each other by a connector at one end of the engine. Intermediate walls are formed between adjacent bores. A connecting passage is formed in each intermediate wall for connecting the first and the second coolant passages. Water as a coolant flows from an inlet, which is formed at the other end of the first coolant passage, through, in turn, the first coolant passage, the connector, and the second coolant passage, and flows out from an outlet, which is formed at the other end of the second coolant passage. Water also flows through the connecting passages.

    摘要： A series of method and apparatus advances in the accumulator-type fuel injector art, applicable to both intensified and unintensified accumulator injectors, which cooperate to provide major improvements in internal combustion engine fuel economy, reduction of noise, and reduction of undesirable exhaust emissions, including smoke, oxides of nitrogen and hydrocarbons. According to the invention, injector needle closure speed is increased for sharper fuel cutoff and better atomization proximate closure and needle closure bounce is minimized to minimize fuel dribble proximate closure by reducing both mass and length of the needle, which can be accomplished by a longitudinally divided needle. Hydraulic damping also damps and cushions both needle closing and needle opening. The accumulator cavity and needle spring cavity are separated, enabling the accumulator cavity to be as small as desired for high accumulator closing pressure, while nevertheless enabling a strong, fast-acting spring to be used, both factors cumulatively contributing to good closure atomization. A two-stage needle lift is provided for first injecting a pilot fuel charge for preignition, and then injecting the main fuel charge, thereby eliminating the usual adverse premixed burning. The injection spray pattern is automatically varied for improved engine efficiency over the engine power spectrum by utilizing a pintle-type injector nozzle which is variably controlled according to the quantity of fuel delivered.

    摘要翻译： 蓄能式燃料喷射器技术中的一系列方法和设备的进步，适用于强化和非致密的蓄能器喷射器，它们协同提供内燃机燃料经济性的主要改进，降低噪音和减少不期望的废气排放，包括 烟雾，氮氧化物和碳氢化合物。 根据本发明，喷射器针头关闭速度增加以更清晰的燃料切断和靠近闭合的更好的雾化，并且使针闭合反弹最小化，以通过减小针的质量和长度来最小化靠近闭合的燃料喷射，这可以通过纵向分割 针。 液压阻尼器还可以阻止和靠垫针头和针头开口。 蓄能器空腔和针簧弹簧腔是分开的，使得蓄能器空腔能够尽可能小以满足高蓄能器关闭压力，同时仍然能够使用强力，快速作用的弹簧，这两个因素累积地有助于良好的闭合雾化。 提供两级提针，用于首先注入用于预燃的先导燃料装料，然后注入主燃料装药，从而消除通常的不利预混燃烧。 通过利用根据输送的燃料量可变地控制的枢轴型喷射器喷嘴，注射喷雾模式自动变化，以提高发动机功率谱上的发动机效率。
