Even though they're just a lump of cast aluminum, crankcases
do wear out and before that, they sometimes crack.
The current technological method to design crankcases
is to use computer-aided engineering methods, which assume homogenous behavior.
Other specifications include pistons being produced from an aluminum-based alloy, crankshafts from an iron-based alloy, camshafts from an iron-based alloy and made from a single piece of metal, and crankcases
and cylinder heads from an aluminum-based alloy.
Over the past decade, legislative efforts have accelerated to mandate the closing of diesel engine crankcases
and eliminate the venting of their emissions into the atmosphere.
in Tangshan, Hebei Province will start producing crankcases
and other parts in November 2006 in time for a production increase at the Toyota plant, according to Aisin.
The MT-55F, MT-65H and MT-74F are 4-cycle Mikasa rammers from Multiquip offer a new look, stronger crankcases
, a narrower width to allow greater utilization in trenches, and a built-in primary engine air filter to simplify service and maintenance.
A new line of aluminum liquid level gages can be used to view oil levels in hydraulic reservoirs, gearboxes, bearing housings, crankcases
, transformers, and machinery off reservoirs.
There are four crankshaft lines for smaller engines, three camshaft lines, three flywheel lines, six cylinder-head lines, four lines to machine covered crankcases
, and five crankcase
lines for larger engines.
The Alfdex system offers the market high-efficiency removal of oil droplets and soot particles from the ventilation gas in diesel engine crankcases
, also known as blow-by or crankcase
The assets of Danbury brought us new opportunities which will continue at the San Antonio, Texas, location, such as PMA Lycoming part manufacturing (cylinders, crankcases
, crankshafts and pistons, plus manufacturing the Titan engine line for the experimental/kit market.
Gebruder Gienanth-Eisenberg GmbH produces 400 coldbox sand cores per day for the production of high performance six- and eight-cylinder crankcases
at its gray, ductile and compacted graphite iron shop in Eisenberg.
Closing diesel engine crankcases
is a technology path receiving increased attention as global emissions standards become more stringent.
