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： A double-acting reciprocating motor with uni-directional fluid flow path comprises a piston disposed within a cylinder. A first chamber is defined by the cylinder space between the piston and a cylinder base. A second chamber is defined by the cylinder space between the piston and a cylinder head. Fluid is introduced into the motor through an inlet port and into the first chamber. A pass-through valve controls the flow of fluid from the first chamber to the second chamber. An outlet valve regulates the draining of fluid from the second chamber through an outlet port. The outlet port and the inlet port are associated with opposite ends of the motor. Differential fluid pressure urges the piston towards the cylinder head when the pass-through valve is closed and the outlet valve is open. The piston surface facing the second chamber is larger than the piston surface facing the first chamber, so the piston moves towards the cylinder base when the pass-through valve is open and the outlet valve is closed.

摘要： A hydraulic drive system (100) comprises a hydraulic actuator (110) comprising a piston (118) reciprocable between two cylinder heads (114, 116) for actuating a machine. A flow switching device (130) reverses the direction of hydraulic fluid flow to and from chambers (120, 122) on opposite sides of the piston (118). The piston (118) stops at the end of each piston stroke when a shuttle valve (124) associated with the piston (118) opens to allow hydraulic fluid to flow between the chambers (120, 122) cancelling the differential pressure that acts on the piston (118) to cause reciprocal movement. A controller (170) is programmed to determine when the piston (118) reaches the end of each stroke based upon at least one of hydraulic pump (140) speed, hydraulic fluid pressure, or elapsed time, with each of these measured during each stroke. The controller (170) then sends an electronic signal to command the flow switching device (130) to reverse the direction of hydraulic fluid flow.

摘要： This disclosure teaches a method of controlling a direct injection internal combustion engine and predicting the behaviour of a direct injection internal combustion engine. An estimation of initial cylinder pressure, air flow and EGR flow (if applicable) is used to establish a system that provides engine behaviour by integrating an injection module, combustion module and engine control module to provide data indicative of engine behaviour such as brake torque and power, air flow, EGR flow, cylinder pressure, brake specific fuel consumption, start of combustion, heat release rate, turbo-charger speed and other variables. These values can then be used to adjust commanded variables such as start of injection, commanded pulse width, rail pressure to meet operator demand. Also the output data can be used as a tool to determine how a conceptualised engine design will behave. This is particularly useful for gaseous-fuelled internal combustion engines where cylinder pressure influences behaviour of injected gases in light of the fact that rail pressure and cylinder pressure are, generally, of a similar magnitude.

摘要： A seal assembly (116) for providing sealing between a movable cylindrical body (112) and a housing body (110) comprises separate sealing mechanisms for providing static and dynamic sealing. The seal assembly is associated in fixed relationship with either the cylindrical body or the housing body and provides a static seal with the body it is associated with and a dynamic seal with the body that moves relative to the seal assembly. The static sealing mechanism is temperature-activated so that within the operating temperature range, a metallic member (118) of the static seal mechanism is pressed tightly against the associated body to provide a fluid tight static seal. The temperature-activation is caused by the metallic member having a different thermal expansion coefficient than the associated body. The dynamic seal may employ known dynamic sealing mechanisms such as spring-energized seals, interference fit seals, and/or temperature-activated seals.

摘要： A hydraulically actuated dual fuel injector (1) separately injects a gaseous fuel and a liquid fuel into a combustion chamber of an internal combustion engine. The injector comprises: (a) an injector body; (b) a hydraulic fluid inlet port (7) for a pressurized hydraulic fluid, said hydraulic fluid being of sufficient pressure to maintain sealing and to prevent leakage of the gaseous fuel into the hydraulic fluid; (c) a first liquid fuel inlet port (6) for a first liquid fuel; (d) a first injection valve (16) disposed within the injector body fluidly connected to the first fuel inlet port (6) for controlling injection of the first liquid fuel through a first fuel ejection port (5); (e) a second inlet port (23) for a second gaseous fuel; (f) a second injection valve (17) fluidly connected to the second inlet port (23) for controlling injection of the second gaseous fuel through a second fuel ejection port (4); (g) a first two-way control (3) valve which controls the flow of the hydraulic fluid to actuate the first injection valve (16); (h) a second control valve (2) which controls the flow of the hydraulic fluid to actuate the second injection valve (17); (i) a metering device (15) within the injector body for metering the amount of first liquid fuel injected by the first injection valve (16); and (j) a fluid seal cavity (22) in the injector body which prevents leakage of the second gaseous fuel.
