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 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： An internal combustion engine includes an electromagnetic valve actuator having an armature between upper and lower electromagnets with a stem extending through one electromagnet and guided by a bushing with increased clearance about at least a portion of the inner circumference in at least a middle portion of the bushing to reduce oil shear length and associated viscous friction in the actuator. A two-piece intake/exhaust valve guide includes a lower half with a stepped outer diameter cooperating with a counter-bored hole in the cylinder head to provide a positive stop. The upper and lower halves of the valve guide have increased clearance relative to the valve stem around at least a portion of the inner circumference to reduce oil shear length and associated viscous friction. Reducing viscous friction of the actuator and associated valve guide improves system robustness by decreasing the system sensitivity to temperature.
