Wallpaper Engine is an application for Windows with a companion app on Android [3] which allows users to use and create animated and interactive wallpapers, similar to the defunct Windows DreamScene. Wallpapers are shared through the Steam Workshop functionality as user-created downloadable content .
For the cylinder bores of hypoeutectic aluminum-silicon alloy blocks, PTWA's main advantages over cast iron liners are reduced weight and cost. The thinner bore surface also allows for more compact bore spacing, and can potentially provide better heat transfer. Automotive engines that use PTWA include Nissan VR38DETT, [3] and Ford Coyote.
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single ...

Alusil as a hypereutectic aluminium-silicon alloy (EN AC-AlSi17Cu4Mg / EN AC-48100 or A390) contains approximately 78% aluminium and 17% silicon. [1] [2] This alloy was theoretically conceived in 1927 by Schweizer & Fehrenbach, [3] of Badener Metall-Waren-Fabrik, [4] but practically created only by Lancia [5] in the same year, for its car engines.
De Dion-Bouton engine with monobloc cylinder heads, but cylinders separate from crankcase c. 1905 [1]. A monobloc or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later.
Nikasil was introduced by Mahle in 1967 and was initially developed to allow Wankel engine apex seals to work directly against the aluminum block. [1] This coating allowed aluminum cylinders and pistons to work directly against each other with low wear and friction.
Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst or pop out, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block.
