Unreferenced date May 2008 A crossflow cylinderhead is a cylinderhead that features the intake manifold intake and exhaust manifold exhaust ports on opposite sides. The gases can be thought to flow across the head. This is in contrast to reverse flow cylinderhead designs that have the ports on the same side. A crossflow head gives engine tuning better performance , but the popular explanation put forward for this &mdash that the gases don t have to change direction and hence are moved into and out of the cylinder more efficiently &mdash is a simplification since there is no continuous flow because of poppet valve valve opening and closing. But since there is overlap between the intake and exhaust profiles there is a point in which both valves are open. At that point the inertia of the exhaust gases leaving the cylinder helps to aspirate the intake gases into the cylinder. The other main reason for a crossflow s performance is that the ports and valves can be larger and its physical separation of the hot exhaust manifold keeps the air in the intake manifold cooler. Most modern engines are of a crossflow design. Crossflow is often used to refer specifically to Ford Motor Company s Ford Kent engine Kent Crossflow 4 cylinder Overhead valve OHV engine. This unit has been used in cars from the 1960s up to the present day, albeit with the addition of fuel injection and a modern engine management system . The term was also briefly used in the early 1980s in Australia for the revised 4.1 litre inline six cylinder engine in Ford s Australian large family car, the Ford Falcon Australia Falcon .

Multiple issues unreferenced September 2008 context January 2008 A reverse flow or non crossflow cylinderhead is one that locates the intake and exhaust ports on the same side of the engine.

Cylinder 1024 is the first cylinder disk drive cylinder of a hard disk that was inaccessible in the original IBM PC compatible hardware specification, INT 13H interrupt 13h , which uses cylinderhead sector addressing. At boot time very old BIOS of many PCs could only access the first 1024 cylinders, numbered 0 to 1023 as CHS addressing only defines 10 bits for the cylinder count 2 10 1024 . This was a problem for operating system s on the x86 platform as the BIOS must be able to load the bootloader and the entire kernel computer science kernel image into memory. Both of these must, therefore, be located on the first 1024 cylinders of the disk. Older versions of Microsoft Windows resolved this by necessitating that the operating system was installed to the first partition. Because of this bug, users of the Linux operating system have traditionally created a tt boot tt partition to reside within the first 1024 cylinders of the disk, containing little more than the Kernel computer science kernel and bootloader.

The master cylinder is a control device that converts non hydraulic pressure commonly from a driver s foot into hydraulic pressure , in order to move other device s which are located at the other end of the hydraulic system, such as one or more slave cylinders . As piston s move along the bore of the master cylinder, this movement is transferred through the hydraulic fluid, to result in a movement of the slave cylinder s . The hydraulic pressure created by moving a piston inside the bore of the master cylinder toward the slave cylinder s compresses the fluid evenly, but by varying the comparative surface area of the master cylinder and or each slave cylinder, one will vary the amount of force and displacement applied to each slave cylinder relative to the amount of force and displacement that was applied to the master cylinder . Vehicle applications The most common vehicle uses of master cylinders are in brake and clutch systems. In brake systems, the operated devices are cylinders inside of brake caliper s and or drum brakes these cylinders may be called wheel cylinders or slave cylinders, and they push the brake pad s towards a surface that rotates with the wheel this surface is typically either a drum, or a disc, a.k.a. a rotor until the stationary brake pad s create friction against that rotating surface typically the rotating surface is metal or ceramic ... system, the device which the master cylinder operates is called the slave cylinder it moves ... cylinder supplies the master cylinder with enough brake fluid to avoid air from entering the master cylinder even the typical clutch uses brake fluid, but it may also be referred to as clutch fluid in a clutch application .

Orphan date December 2007 A wheel cylinder is a component in a drum brake system. It is located in each wheel and is usually at the top, above the shoes. Its responsibility is to exert force onto the shoes so they can contact the drum and stop the vehicle with friction . What connects these wheel cylinders to the shoes are usually small rods shaped like a birds beak. It is very similar to a master cylinder and functions in pretty much the same way, consisting of just a simple little plunger on the inside. On older vehicles these will begin to leak and hinder the performance of the brakes, but are normally inexpensive and easy to replace. The wheel cylinder consists of a cylinder that has two pistons, one on each side. Each piston has a rubber seal and a shaft that connects the piston with a brake shoe. When brake pressure is applied, the pistons are forced out pushing the shoes into contact with the drum. Wheel cylinders must be rebuilt or replaced if they show signs of leaking. automotive part stub Category Brakes ... more details

The first main advantage to a cylinder lock, also known as a profile cylinder lock, is that the cylinder may be changed without altering the boltwork hardware. Removing the cylinder typically requires only loosening a set screw, then unscrewing the cylinder from the boltwork. The second is that it is usually possible to obtain, from various lock manufacturers, cylinders in different formats that can all be used with the same type of key. This allows the user to have keyed alike, and master keyed systems that incorporate a wide variety of different types of lock, such as nightlatches, deadbolts and roller door locks.
