摘要： A fuel injection valve is provided for co-injecting a liquid and a gaseous fuel into the combustion chamber of an internal combustion engine. A solid needle regulates the injection of liquid and gaseous fuels from a cavity in the fuel injection valve into the combustion chamber when the needle is lifted to its open position. In preferred embodiments, liquid fuel is metered and pressurized in an intensifier's cylinder provided within the valve body and the liquid fuel is delivered through a restricted flow passage into the cavity where it mixes with the gaseous fuel. The restricted flow passage can be formed by a small passage formed in the valve body or an annular passage between the needle and the valve body.

摘要： In a gaseous-fuelled stoichiometric compression ignition internal combustion engine, a pilot fuel is injected directly into the combustion chamber to help initiate a multi-point ignition. The engine provides performance improvements approaching those of high pressure direct injection engines but with less complexity because the gaseous fuel is introduced into the intake air subsystem at relatively low pressure and as a result of the stoichiometric combustion, the low oxygen content in the combustion products exiting the combustion chamber allows the use of a three-way catalyst instead of other after treatment arrangements normally associated with conventional compression ignition engines that require the addition of a reductant.

摘要： Advantages such as reduced emissions of NOx can be achieved if engines are fuelled with mixtures of gaseous fuels such as hydrogen and natural gas. It is also desirable to store the gaseous fuels separately so that the fuel mixture ratio can be changed responsive to engine operating conditions. However, compared to liquid fuels, a problem with storing gaseous fuels is that they generally require larger storage volumes to hold an equivalent amount of fuel on an energy basis. There are also obstacles to storing some gaseous fuels such as hydrogen in liquefied form because of the energy required to liquefy them and the extremely low temperatures needed to store such gaseous fuels in liquefied form. The invention relates to an apparatus for increasing the storage density of gaseous fuels such as hydrogen by storing them in gaseous form at high pressures and at sub-ambient temperatures. An apparatus is provided for separately storing a first gaseous fuel and a second gaseous fuel. A first vessel defines a first thermally insulated space for holding the first gaseous fuel in a liquefied form. A second thermally insulated space that can hold the second fuel is disposed within the first vessel. The second thermally insulated space is separated from the first thermally insulated space by a thermally conductive fluid barrier. The second gaseous fuel liquefies at a lower temperature than the first gaseous fuel, whereby the second gaseous fuel can be stored within the second thermally insulated space in a gaseous form at a sub-ambient temperature.
摘要翻译：如果使用气体燃料（如氢气和天然气）的混合物来燃烧发动机，则可以实现减少NOx排放的优点。还期望分开地储存气体燃料，使得可以响应于发动机操作条件改变燃料混合比。然而，与液体燃料相比，存储气体燃料的问题在于它们通常需要更大的储存量以在能量基础上保持等量的燃料。由于液化它们所需的能量以及以液化形式存储这种气体燃料所需的极低温度，因此存在一些气态燃料如氢气的液化形式存在障碍。本发明涉及一种用于通过将气体燃料如氢气储存在高压和低于环境温度下的气体燃料来提高其储存密度的装置。提供了用于分别存储第一气体燃料和第二气体燃料的装置。第一容器限定用于将第一气态燃料以液化形式保持的第一绝热空间。可以容纳第二燃料的第二绝热空间设置在第一容器内。第二隔热空间通过导热流体屏障与第一绝热空间分离。第二气体燃料在比第一气态燃料低的温度下液化，由此第二气体燃料可以在亚环境温度下以气态形式储存在第二绝热空间内。

摘要： A gaseous-fuelled internal combustion engine and a method of operating same are provided for improving combustion stability and reducing emissions of NOx, PM, and unburned hydrocarbons. The method comprises fuelling an internal combustion engine with hydrogen and natural gas, which can be directly injected into the combustion chamber together or introduced separately. Of the total gaseous fuel delivered to the engine, at least 5% by volume at standard temperature and pressure is hydrogen. For at least one engine operating condition, the ratio of fuel rail pressure to peak in-cylinder pressure is at least 1.5: 1. The engine comprises a combustion chamber defined by a cylinder, a cylinder head, and a piston movable within the cylinder; and a fuel injection valve operable for introducing the gaseous fuel mixture directly into the combustion chamber, or two separate fuel injection valves for introducing the methane and hydrogen separately. An electronic controller is in communication with actuator(s) for the fuel injection valve(s) for controlling timing for operating the fuel injection valve(s). The engine has a compression ratio of at least 14:1.

摘要： A method and apparatus is disclosed for adjusting pilot fuel injection timing in relation to a main fuel injection timing into a piston cylinder of an operating gaseous-fuelled direct injection internal combustion engine using high levels of EGR. A set of engine parameters are monitored which determine engine load and engine speed and an indicator of EGR concentration within the intake charge. Pilot fuel timing relative to main fuel injection timing is then adjusted according to the engine parameters. High levels of EGR are shown to be tolerated with relatively limited penalties in regards to other emissions typically found with high EGR by reducing the relative injection timing the pilot fuel as compared to main fuel injection timing.

摘要： A method for providing a directly injected gaseous fuel into the combustion chamber of an internal combustion engine is provided. The compressibility of the gaseous fuel is used to provide a fuel to the combustion chamber that is injected over all engine operating conditions at pressures that result in fuel jet speeds beyond the injector nozzle in excess of sonic speeds as determined in reference to the combustion chamber environment. The resulting fuel injection speed results in the fuel passing through shock waves within the combustion chamber, which, in turn, promotes combustion of the fuel by promoting turbulence and mixing of the fuel and intake charge within the combustion chamber where fuel burns in a non-premixed combustion mode.

摘要： A method and apparatus is disclosed for controlling to a target heat release rate (HRR) using a HRR control lever, namely, pilot fuel timing and/or pilot fuel quantity, used in a gaseous-fuelled compression ignition internal combustion engine. The mechanism to control HRR to a target HRR provides improved performance and emissions for such an engine. A target HRR is determined for a cycle of an engine. A HRR control lever is then used to adjust to the target HRR in consideration of combustion conditions in the engine and the difference between the target HRR and cycle HRR predicted for the cycle by reference to, by way of example, a derived HRR trace from a previous cycle, a pressure trace, a measured property of the exhaust gas directly determined or mapped values provided during calibration allowing for adjustment to a target HRR for the engine. The mapped values can be cross-referenced to the combustion conditions in the engine.

摘要： A method and apparatus for introducing gaseous fuel into a piston cylinder of an operating internal combustion engine in two separate stages involves monitoring a set of engine parameters, determining engine load and engine speed from the set of engine parameters, in a first stage, introducing a first portion of the gaseous fuel into the cylinder where the first portion of gaseous fuel forms a substantially homogeneous mixture comprising gaseous fuel and air prior to combustion, and in a second stage, occurring sequentially after the first stage, introducing a second portion of the gaseous fuel into the cylinder. The gaseous fuel quantity is variable in response to at least one of engine load and engine speed. Initiation and duration for at least one of the first and second stages is also variable in response to at least one of engine load and engine speed.
