摘要： An exhaust system comprises a conical shell having an indentation helically traversing the exhaust passage so as to impart mixing on an engine exhaust gas flowing through an inner passage defined by the conical shell. The indentation may be formed into the conical shell via a stamping process.

摘要： An exhaust system comprises a conical shell having an indentation traversing the exhaust passage in a coiled path so as to impart mixing on an engine exhaust gas flowing through an inner passage defined by the conical shell. The indentation may be formed into the conical shell via a stamping process.

摘要： A diesel particulate filter (DPF) configured to separate a particulate from an engine exhaust is provided. The DPF comprises a downstream filtration stage including a plurality of downstream channels, an upstream filtration stage disposed upstream of and in fluidic communication with the downstream filtration stage, and including a plurality of upstream channels, and a shell at least partly enclosing the downstream filtration stage and the upstream filtration stage, the shell including an inlet configured to conduct the engine exhaust to the upstream filtration stage and an outlet configured to release the engine exhaust from the downstream filtration stage. The plurality of upstream channels may include a plurality of open upstream channels, the arrangement of which disperses the particulate more evenly over the plurality of downstream channels, as more flow is directed away from the major axis of the filter. In this way, during regeneration, it is possible to reduce one or both of longitudinal and radial thermal gradients, and thereby improve structural integrity of the filter.

摘要： An engine exhaust component is provided. The engine exhaust component may include a plurality of coolant passages having parallel coolant flow, each coolant passage at least partially surrounding a respectively corresponding exhaust runner. The engine exhaust component may further include a coolant inlet manifold coupled to each of the coolant passages and a coolant outlet manifold coupled to each of the coolant passages. In this way, more even and controlled cooling can be provided.

摘要： An adjustable camshaft system for an automotive engine includes a camshaft having machined and fabricated axially-directed control passages combined with an oil-activated camshaft phaser. The fabricated oil control passages are formed within a portion of the camshaft having an outside diameter which is substantially equal to the outside diameter of other portions of the camshaft fitted within bearings carried within the engine's cylinder head.
