摘要： A directly actuated injection valve comprises a hollow valve housing (102), a valve needle (119) disposed within the hollow interior, a needle spring (116), an actuator assembly, and a hydraulic link assembly. The actuator assembly generates an opening force that acts against the needle spring (116) to open the valve. The hydraulic link assembly is interposed between the valve needle (114) and the needle spring (116) and the actuator assembly. The hydraulic link assembly transmits respective closing and opening forces to the valve needle (114). The hydraulic link preferably comprises a piston (114b) disposed within a cylinder (160) that is filled with a hydraulic fluid. The opening and closing forces are transmitted through a thickness of the hydraulic fluid that is trapped between the planar surfaces of the piston (114b) and the head (162) and base of the hydraulic cylinder. In the preferred embodiment, the thickness of the hydraulic fluid trapped between the piston (114b) and cylinder head (162) or base is automatically adjustable in response to changes in the dimensional relationship between components of the injection valve to maintain a desired valve needle lift when the actuator assembly is activated. When the actuator assembly comprises a magnetostrictive or piezoelectric member (130), the movements of the valve needle (114) can be controlled by the application of a shaped control pulse or waveform to improve the speed of the opening and closing motion of the valve needle (114), and to reduce the impact of the valve needle on the valve seat upon closing.

摘要： Disclosed is a glow member, preferably in the shape of a ring, to assist ignition and combustion of a fuel used in an internal combustion engine. A fuel injection valve injects a plurality of fuel jets directly into a combustion chamber during operation of the engine so that the fuel jets are aimed to the proximity of the glow member such that ignition of fuel in each fuel jet is assisted by the glow member. The glow member is made from high temperature materials and can include catalytic materials to further promote combustion. The glow member can be actively heated, for example by an electric current, in addition to being passively heated by the heat generated within the combustion chamber by the combustion of the fuel therein.

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.
