Editing Engine block (section)

=== Integrated cylinder block and crankcase ===
Most engine blocks today, except some unusual V or radial engines and large marine engines, use a monobloc design with one block for all cylinders plus an integrated crankcase. In such cases, the skirts of the cylinder banks form a crankcase area of sorts, which is still often called a crankcase despite no longer being a discrete part.

Using steel cylinder liners and [[Main bearing|bearing]] shells minimizes the effect of the relative softness of aluminium. Some engine designs use [[plasma transferred wire arc thermal spraying]], instead of cylinder sleeves, to further reduce weight. These types of engines can also be made of [[compacted graphite iron]], such as in some diesel engines.<ref>{{cite news |url= http://foundrymag.com/materials/navistar-now-producing-engine-blocks-heads-cgi |title=Navistar Now Producing Engine Blocks, Heads in CGI |work=Foundry Management & Technology |first=Robert |last=Brooks |date=January 25, 2012 |access-date=May 2, 2017}}</ref>
