摘要： A method of forming a bowl in a top surface of a piston for an internal combustion engine includes machining the top surface of the piston to form a spherical depression in the top surface wherein the top surface comprises a dome prior to the machining and a center of the bowl is displaced from a center of the piston by at least one-quarter of a diameter of the piston. In one embodiment, the method includes machining recesses in the top surface aligned, respectively, with intake valves, an exhaust valve, and spark plug when installed. Because the bowl is smooth and shallow, the surface area of the combustion chamber is less than with a deeper bowl of complicated shape. Lowering surface area in the combustion chamber leads to improved fuel economy.
摘要翻译：在用于内燃机的活塞的顶表面中形成碗的方法包括加工活塞的顶表面以在顶表面中形成球形凹陷，其中顶表面包括在加工之前的圆顶和中心碗从活塞的中心位移至活塞直径的至少四分之一。在一个实施例中，该方法包括在安装时将分别与进气门，排气阀和火花塞对准的顶表面中的凹槽加工。由于碗平滑浅，所以燃烧室的表面积比较深的碗形复杂。降低燃烧室中的表面积导致改进的燃料经济性。

摘要： A combustion system for a direct-injection, spark-ignition engine is disclosed. A side-mounted fuel injector located outboard the intake valves directs multiple fuel jets into a shallow, spherical bowl formed in a domed piston. Both good mixing to facilitate good air utilization with early injection and an ignitable mixture at the spark plug with late injection to facilitate cold start are provided with such a combustion system. Because the bowl is smooth and shallow, the surface area of the combustion chamber is less than with a deeper bowl of complicated shape. Lowering surface area in the combustion chamber leads to improved fuel economy.

摘要： A data processing system includes a processor core and a hardware module. The processor core performs tasks on data packets. The hardware module stores a first ordering scope identifier at a first storage location of the ordering scope manager. The first ordering scope identifier indicates a first ordering scope that a first task is operating in. The ordering scope manager increments the first ordering scope identifier to create a new ordering scope identifier. In response to determining that the processor core is authorized to transition the first task from the first ordering scope to a second ordering scope associated with the new ordering scope identifier, the ordering scope manager provides hint information to the processor core. The processor core transitions from the first ordering scope to the second ordering scope without completing a task switch in response to the hint information.

摘要： In one or more embodiments, a data processing system can include at least one core capable of executing instructions of an instruction set architecture and a triggered memory map access (tMMA) system coupled to the at least one core. The tMMA system can receive one or more events and, in response, perform one or more actions. For example, the actions can include transactions which can include a write to a an address of the memory map, a read from an address of the memory map, a read followed by write to two respective addresses of the memory map, and/or a fetch transaction. A result of a transaction (e.g., data read, data written, error, etc.) can be used in generating a trace message. For example, the tMMA system can generate a trace message that includes the result of the transaction and send the trace message to a trace message bus.

The magnetron (436) preferably is a small one having a stronger outer pole (442) of a first polarity surrounding a weaker inner pole (440) of a second polarity all on a yoke (444) and rotates about the axis (438) of the chamber using rotation means (446, 448, 450). The auxiliary magnets (462) preferably have the first polarity to draw the unbalanced magnetic field (460) towards the wafer (424), which is on a pedestal (422) supplied with power (454). Argon (426) is supplied through a valve (428). The target (416) is supplied with power (434).
