摘要： A method and apparatus for combusting diesel, gasoline, kerosene, alcohol and other compression ignition fuels in either direct or indirect injection compression auto ignition internal combustion engines which enables such engines to operate at low compressions. The apparatus includes an ignition chamber which functions to receive a portion of the incoming fuel charge thereby concentrating such portion in an area separate from the auxiliary or primary combustion chambers. The ignition chamber is predominantly in convective heat exchange relationship with the primary combustion chamber and has at least one opening therein designed and oriented with respect to the interior thereof to create a nonturbulent circular air flow therein during the compression stroke of the engine which will cause the lighter components of the fuel charge directed therein to be concentrated adjacent a central zone where such lighter and generally more volatile components of the fuel charge will be ignited by the heat therein to thereby initiate a controlled ignition of the remaining fuel in the ignition chamber. The amount of fuel in the fuel charge directed into the ignition chamber will remain generally constant regardless of the load on the engine and its operating speed with the amount of such fuel charge depending on the engine compression ratio and the relative sizes of the ignition and combustion chambers. The amount of such a fuel charge should be as great as possible while still insuring complete fuel combustion therein. The amount of heat released within the ignition chamber compensates for the heat lost through operating a lower compressions and is sufficient to ignite the fuel in the main burning or combustion chamber.
摘要翻译：一种用于在直接或间接注射压缩自动点火内燃机中燃烧柴油，汽油，煤油，酒精和其它压燃点燃燃料的方法和装置，其使得这种发动机能够以低压缩运行。该装置包括点火室，其功能是接收一部分进入的燃料电荷，从而将这些部分集中在与辅助或主燃烧室分离的区域中。点火室主要与主燃烧室处于对流热交换关系，并且其中至少有一个开口相对于其内部设计和定向，以在发动机的压缩冲程期间在其中产生不湍流的圆形空气流，这将使得导向其中的燃料进料的较轻部件被集中在中心区域附近，其中燃料装料的较轻且通常更易挥发的组分将被其中的热量点燃，从而启动点燃室中的剩余燃料的受控着火。引导到点火室中的燃料进料中的燃料量将保持大体上恒定，而不管发动机的负载和其运行速度如何，这些燃料的量取决于发动机的压缩比和点燃和燃烧的相对尺寸房间。这种燃料充量的量应当尽可能大，同时仍然确保其中完全燃料燃烧。点火室内释放的热量通过操作较低的压缩来补偿热量损失，并足以点燃主燃烧室或燃烧室中的燃料。

摘要： A compression ignition engine includes a piston having a barrier protruding axially therefrom. The barrier at least partly defines a combustion chamber having a first zone separated from a second zone by the barrier. An initial fuel charge is supplied into the combustion chamber, and a subsequent fuel charge is supplied into the first zone, the subsequent fuel charge having greater reactivity than the initial fuel charge. The fuel charges are compressed to induce ignition and combustion of the fuel charges, such that the subsequent fuel charge burns within the first zone to produce hot gases, and the hot gases flow across the barrier to effect combustion of the initial fuel charge within the second zone.

摘要： A premixed charge of air and a low reactivity fuel is created in a combustion chamber space by the time at which a piston comes substantially to top dead center at which time a high reactivity fuel is directly injected into a central zone of the combustion chamber space which is bounded partially by a central bowl cavity in the piston head which is itself surrounded by an upright intermediate wall. The high reactivity fuel combusts by conventional diesel combustion and creates a flame front which propagates into an outer zone of the combustion chamber space which is bounded partially by the upright intermediate wall and an outer bowl cavity in the piston head to initiate combustion of the premixed air-fuel charge in the outer zone of the combustion chamber space.

The bowl includes an inner surface that defines a volume configured to receive a fuel-air mixture, the inner surface of the bowl including at least one surface feature that forms at least one edge portion as a target for the fuel spray, the edge portion defined by two or more surface portions. The surface feature may protrude from the inner surface of the bowl or may be recessed into the inner surface. Such surface features may reduce soot and improve fuel-air mixing.

摘要： We provide a torch cell for a dual gas-liquid fuel engine, the torch cell has a torch cell nozzle at one end thereof and the other end having appropriate means to connect said torch cell to a fuel supply. A fuel injector is mounted in said torch cell at a predetermined angle to an axis of said torch cell. The torch cell has an auto-ignition chamber that is in operative communication with the injector by an injector nozzle passageway. The injector nozzle passageway enters the auto-ignition chamber at a predetermined angle relative to the cell axis. The torch cell provides an improved dual fuel engine and method for operating a dual fuel engine by use of its autoignition chamber. We also provide a cylinder head which can replace present dual fuel engine cylinder heads. Our cylinder head has at least one of our torch cells operatively connected to the cylinder head.
