The essential mechanical application loads of a crankcase are caused by the pressures apparent during ignition.
Crankcase durability is evaluated on a simplified two-axis impulse test stand (Fig.
2 Procedure--Step casting and crankcase samples were used in numerous fatigue test runs.
Interest in the Alfdex crankcase gas cleaning system is pushed by tougher engine legislation that takes into account not only exhaust pipe discharges but also other discharges as well, e.
Alfdex AB is firmly established as the worlds' leading supplier of highly efficient proprietary crankcase gas cleaning solutions.
The horizontal production center is configured to permit three-setup processing of a family of four engine crankcase castings using two independent work zones," explains Kevin Ramus, manufacturing engineer in charge of the project.
Processing of a raw crankcase casting begins on the Zone 1 B-axis rotary table.
While a second raw casting is machined in Zone 1, the operator refixtures the first workpiece for processing in the Zone 2 A-axis vertical trunnion for machining of the crankcase thrust face and bearing cap assembly using a right-angle milling head.
Following automatic part probing and manual gaging of several critical dimensions, the crankcase is prepared for refixturing on the B-axis rotary table and processed for a second time in Zone 1.
If the cap on the Washington Monument is the most famous aluminum casting, the block and crankcase
of the Wright Brothers' first plane to fly at Kitty Hawk in 1903 are the second most famous.
With approximately SEK 1 Billion in currently acknowledged orders over the next 3-5 years, Alfdex AB is firmly established as the worlds' leading supplier of proprietary crankcase gas cleaning solutions.
Global interest in the Alfdex crankcase gas cleaning system is pushed by tougher engine legislation which will take into account not only exhaust pipe discharges but other discharges as well, e.
