Splayed arch tops the splayed window opening. In architecture, a splayed opening is a wall opening that is narrower on one side of the wall and wider on another. When used for a splayed window, it allows more light to enter the room. In fortifications, a splayed opening is used to broaden the arc of fire (cf. embrasure, loophole). [1]
The main advantage of the reverse-flow cylinder head is that both the entering inlet charge and the exiting exhaust gas cause a tendency to swirl in the same direction in the combustion chamber. [1] In a crossflow head the inlet and exhaust gases promote swirl in opposite directions so that during overlap the swirl changes directions.
It is shown as manufactured with the intake port on the right. The Ford two-liter F2000 engine in stock trim equipped with the head shown above was capable of delivering 115 horsepower at 5500 rpm for a BMEP of 136 psi. Port molds of a highly developed 500 cubic inch aftermarket Pro Stock racing head. Note the height and straightness of the ...
A crossflow head gives better performance than a Reverse-flow cylinder head (though not as good as a uniflow), but the popular explanation put forward for this — that the gases do not have to change direction and hence are moved into and out of the cylinder more efficiently — is a simplification since there is no continuous flow because of valve opening and closing.
Cylinder and ports, viewed from above. Schnuerle porting [1] [2] is a system to improve efficiency of a valveless two-stroke engine by giving better scavenging.The intake and exhaust ports cut in the cylinder wall are shaped to give a more efficient transfer of intake and exhaust gases.

In architecture, a splayed arch (also sluing arch [1]) is an arch where the springings are not parallel ("splayed"), causing an opening on the exterior side of an arch to be different (usually wider) than the interior one. The intrados of a splayed arch is not generally cylindrical as it is for typical arch, but has a conical shape. [2] [3]
The FBI searched the home of Deputy Mayor Brian Williams while looking into a bomb threat he 'allegedly made against City Hall earlier this year,' said a spokesperson for Mayor Karen Bass.
