Abstract: An internal combustion engine in which a required reformed-fuel heat generation quantity (required output cylinder heat generation quantity) is calculated based on a required engine power and the thermal efficiency of an output cylinder. An estimated reformed fuel heat generation quantity is calculated based on the molar number of reformed fuel, mole fraction of each gas component in the reformed fuel, and heat generation quantity of each gas component in the reformed fuel. When a value resulting from subtracting the estimated reformed fuel heat generation quantity from the required reformed-fuel heat generation quantity is negative, a fuel reforming operation is not executed, assuming that there is a possibility that surplus reformed fuel may be generated. For example, a fuel supply from an injector to a fuel reformation chamber is stopped.

Abstract: Various methods and systems are provided for a multi-fuel capable engine. In one example, a system comprises an engine having at least one cylinder controlled via an intake valve, a first fuel system to deliver liquid fuel and a second fuel system to deliver gaseous fuel to the at least one cylinder, a variable valve timing actuation system to adjust one or more of an opening or a closing timing of the intake valve, and a controller. The controller is configured to, during a liquid fuel only mode, adjust the variable valve timing actuation system to close the intake valve at a first timing based at least on engine load, and during a multi-fuel mode, adjust the variable valve timing actuation system to close the intake valve at a second timing.

The system can include a first set of fuel injectors that are configured to deliver a primary fuel to an engine and can include a second set of fuel injectors that are configured to deliver a secondary fuel to the engine. The bi-fuel control system can operate in either a primary operational state in which the first set of injectors is used or a secondary operational state in which the second set of injectors is used. In either operational state, the electronic control module can control the respective set of injectors independently from the control unit.

Abstract: A machine includes a compression ignition engine fueled from common rail fuel injectors that predominately inject natural gas fuel that is compression ignited with a small pilot injection of liquid diesel fuel. When an engine shutdown command is communicated to an electronic controller, the supply of gaseous fuel to the gas rail is stopped and the gaseous fuel common rail is depressurized by continuing to run the engine and inject gaseous and liquid fuels while commanding a liquid pressure greater than the gas pressure. After the gas rail pressure has achieved an acceptable shutdown pressure, the engine is stopped. The gas rail pressure is then reduced to atmospheric pressure followed by the liquid fuel common rail being reduced to atmosphere pressure after stopping the engine.

Abstract: A two-stroke engine (1) includes a cylinder (2) having a scavenging port (23) and an exhaust port (24), a piston (3) provided in the cylinder (2), a first ejection part (61) for ejecting liquid ammonia into a combustion chamber (20), and a supercharger (5) for pressurizing a suction gas to generate a scavenging gas. In the two-stroke engine (1), the first ejection part (61) ejects liquid ammonia into the combustion chamber (20) within a period of time from when supply of the scavenging gas through the scavenging port (23) into the combustion chamber (20) is started until when the piston (3) next reaches top dead center. It is thus possible to reduce the temperature of gas within the combustion chamber (20) by the heat of vaporization of the liquid ammonia, reduce the pressure in the combustion chamber (20) during compression, and reduce the amount of compression work.

Abstract: A number of systems and methods are disclosed which increase the replenishment interval for anti-knock fluid. This is especially important during activities which require a large amount of anti-knock fluid, such as towing. In some embodiments, the systems and methods are used to reduce anti-knock fluid consumption. For example, changes to engine operation, such as rich operation, spark retarding, upspeeding, and variable valve timing, all serve to reduce the amount of anti-knock fluid required to eliminate knocking. In other embodiments, the composition of the anti-knock fluid is modified, such as by using a higher octane fluid, or through the addition of water to the anti-knock fluid. In other embodiments, the replenishment interval is increased through a larger anti-knock fluid storage capacity. In one embodiment, a three tank system is used where the third tank can be used to store gasoline or anti-knock fluid, depending on the driving conditions.

Abstract: As one example, a fuel rail assembly for supplying pressurized fuel to a plurality of cylinders of an engine is provided. The fuel rail assembly includes a fuel rail housing defining an internal fuel rail volume having at least a first region and a second region; a fuel separation membrane element disposed within the fuel rail housing that segregates the first region from the second region. The membrane element can be configured to pass a first component of a fuel mixture such as an alcohol through the membrane element from the first region to the second region at a higher rate than a second component of the fuel mixture such as a hydrocarbon. The separated alcohol and hydrocarbon components can be provided to the engine in varying relative amounts based on operating conditions.
