    Abstract: Fuel injector apparatus is described, for use on internal combustion engines using slurry fuels, wherein a portion of the engine air mass is passed through an aspirator passage shortly prior to combustion and the slurry fuel is aspirated into this air portion. The thusly mixed air and fuel slurry is distributed throughout the engine combustion chamber via several exit channels from the aspirator. The fuel portion of the slurry is reduced to a very small size when the slurry is prepared, and fine atomization of the slurry during injection into the engine is not needed. Hence relatively low velocity slurry injection can be used and injector wear problems greatly reduced.

    Abstract translation: 描述了用于使用浆料燃料的内燃机的燃料喷射器装置，其中发动机空气质量的一部分在燃烧之前不久就通过吸气通道，并且将浆料燃料吸入该空气部分。 这样混合的空气和燃料浆料通过来自吸气器的几个出口通道分布在整个发动机燃烧室内。 当制备浆料时，浆料的燃料部分被还原成非常小的尺寸，并且不需要在注入发动机期间浆料的细雾化。 因此，可以使用相对低速的浆料喷射，并且喷射器磨损问题大大降低。

    Abstract: An internal combustion engine fueled with a coal-water slurry is described. About 90 percent of the coal-water slurry charge utilized in the power cycle of the engine is directly injected into the main combustion chamber where it is ignited by a hot stream of combustion gases discharged from a pilot combustion chamber of a size less than about 10 percent of the total clearance volume of main combustion chamber with the piston at top dead center. The stream of hot combustion gases is provided by injecting less than about 10 percent of the total coal-water slurry charge into the pilot combustion chamber and using a portion of the air from the main combustion chamber that has been heated by the walls defining the pilot combustion chamber as the ignition source for the coal-water slurry injected into the pilot combustion chamber.

    Abstract: In the engines of this invention the fuel is spread out over the interior pore area of a porous burner volume and the large area of contact with air needed for rapid burning is obtained in this way. The fuel may burn in three ways: partial burning of evaporated fuel in the pore spaces; partial burning of solid carbon fuel deposits in the pore spaces; complete burning of the partial oxidation products outside the pore spaces during expansion. Several engine cycles can be used to burn up any solid carbon deposits formed from the fuel so these engines can efficiently utilize high viscosity residual fuels and slurries of solid char fuels in oil even at very small piston diameters.

    Abstract: A method of controlling fuel injection in a dual fuel engine system includes determining, with a first controller, a diesel injection pulse indicative of a first amount of diesel fuel to be injected into a combustion chamber of the engine and a first timing at which the first amount of diesel fuel is to be injected. The method also includes determining, with a second controller, a combined injection pulse based on the diesel injection pulse. The method further includes injecting the second amount of diesel fuel and the third amount of natural gas into the combustion chamber in accordance with the combined injection pulse. In such a method, injection in accordance with the combined injection pulse results in a combustion event characterized by a second combustion characteristic substantially equal to a first combustion characteristic associated with the diesel injection pulse.

    Abstract: A method and device for obtaining, upon injection, flash evaporation of a liquid in a slurry fuel to aid in ignition and combustion. The device is particularly beneficial for use of coal-water slurry fuels in internal combustion engines such as diesel engines and gas turbines, and in external combustion devices such as boilers and furnaces. The slurry fuel is heated under pressure to near critical temperature in an injector accumulator, where the pressure is sufficiently high to prevent boiling. After injection into a combustion chamber, the water temperature will be well above boiling point at a reduced pressure in the combustion chamber, and flash boiling will preferentially take place at solid-liquid surfaces, resulting in the shattering of water droplets and the subsequent separation of the water from coal particles. This prevents the agglomeration of the coal particles during the subsequent ignition and combustion process, and reduces the energy required to evaporate the water and to heat the coal particles to ignition temperature. The overall effect will be to accelerate the ignition and combustion rates, and to reduce the size of the ash particles formed from the coal.
