2. Cylinder head porting - Wikipedia

   en.wikipedia.org/wiki/Cylinder_head_porting

   Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve their air flow. Cylinder heads, as manufactured, are usually suboptimal for racing applications due to being designed for maximum durability. Ports can be modified for maximum power, minimum fuel consumption, or a ...

3. Ford Y-block engine - Wikipedia

   en.wikipedia.org/wiki/Ford_Y-block_engine

   By 1952 Ford had new, 215 cu in (3.5 L) OHV 6-cylinder engine and Lincoln had a 317 cu in (5.2 L) OHV V8. [1] The company had designed the Y-block for a 1953 introduction, but a shortage of nickel due to the Korean War 's needs prevented the company from manufacturing the engine in sufficient quantities, [ 2 ] delaying it until 1954.

4. Edelbrock - Wikipedia

   en.wikipedia.org/wiki/Edelbrock

   After the war, he produced aluminum racing cylinder heads, in addition to manifolds, which quickly gained him notability among hot rodding hobbyists. Parts to increase an engine's performance were not readily available, so racers built their own. Soon Edelbrock found himself building pieces first for his friends and then for customers. [12]

5. Engine configuration - Wikipedia

   en.wikipedia.org/wiki/Engine_configuration

   VR5 and VR6 engines are very compact and light, having a narrow V angle which allows a single cylinder block and cylinder head. These engines use a single cylinder head so are technically a straight engine with the name "VR" coming from the combination of German words “Verkürzt” and “Reihenmotor” meaning “shortened inline engine”.

6. Ford Modular engine - Wikipedia

   en.wikipedia.org/wiki/Ford_Modular_engine

   The 5.8 is formally known as the Trinity Engine or 5.8-liter V8 engine, which benefits from cylinder heads with improved coolant flow, Ford GT camshafts, piston-cooling oil jets similar to those found on the 5.0 Coyote, new 5-layer MLS head gaskets, an over-rev function that increases the red line to 7000 rpm for up to 8 seconds (from 6250 rpm ...

7. Crossflow cylinder head - Wikipedia

   en.wikipedia.org/wiki/Crossflow_cylinder_head

   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.

8. Cylinder head - Wikipedia

   en.wikipedia.org/wiki/Cylinder_head

   This is also common for motorcycles, and such head/cylinder components are referred to as barrels. Some engines, particularly medium- and large-capacity diesel engines built for industrial, marine, power generation, and heavy traction purposes (large trucks, locomotives, heavy equipment, etc.) have individual cylinder heads for each cylinder ...

9. Dimensionless numbers in fluid mechanics - Wikipedia

   en.wikipedia.org/wiki/Dimensionless_numbers_in...

   Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
