DICTIONARY OF AUTOMOTIVE TERMS - "Sk"

Skate board:

Trucker slang for A flatboard trailer as in "Wish I was pulling a skateboard instead of this drybox".

Skeg:

A deep, vertical, fin-like projection on the bottom of a vessel near the stern

Skeleton construction:

A modern construction layout of the unitary type, using a skeleton-like assembly as the main structural member, thus relieving stress from the body sheet metal.
Also See:
coachbuilt construction
unitary construction

Skew:

The arrangement of laminations on a rotor or armature to provide a slight diagonal pattern of their slots with respect to the shaft axis. This pattern helps to eliminate low-speed cogging effects in an armature and minimize induced vibration in a rotor.

Skewer:

A pin with a loop at one end for insertion and removal. See quick-release skewer.

Skid:

1. A sideways slip or slide of a wheel through failure to grip the ground. Also see anti-skid.
2. To slide sideways (often out of control).
3. To slide in a straight line (as after sudden braking with, maybe, locked brakes).

Also See:
turn into the skid

Skid braking system:

See anti-lock brakes

Skid control system:

A system designed to respond to a locking wheel by relieving hydraulic pressure to the locking brake.

Skid depth:

See tread depth.

Skid lid:

A helmet.

Skid mark:

The mark left on the road surface by the tires, as a result of emergency braking

Skid_pad:

See:
skidpad

Skidpad:

A large area of smooth, flat pavement used for various handling tests. Roadholding is measured by defining a large-diameter circle (Car and Driver magazine uses 300 feet) on the skidpad and measuring the fastest speed at which the car can negotiate the circle without sliding off.

Skidpan:

British term for skidpad.

Skid plate:

A steel, aluminum, or plastic shield attached to the underside of the chassis to protect vulnerable components (oil pan, transmission, differentials, and transfer cases) from off-road obstacles. Also called sump guard

Ski flap:

A flap in the rear bulkhead (behind the rear seat), for long, thin loads (like skis)

Skin:

The outer surface or body panel.
Also See:
door skin
natural oxide skin
seat skin
skins

Skin condenser:

Condenser using the outer surface of the cabinet as the heat radiating medium.

Skinning:

1. The formation of a film on a thick paint layer before the solvents in the layer under it have evaporated
2. When adhesives and sealers contain fast drying solvents, there is a tendency for the applied film to dry rapidly at the surface which slows down the evaporation of the solvent that remains in the film. This condition can lead to blistering, checking or cracking, particularly if the film is exposed to temps near or above the boiling point of the solvent.
3. Many coatings, particularly oxidizing types, have a tendency to skin over when left exposed to the air in an open vessel or in a partially filled container. Later when the material is forced through a spray gun, the air breaks the skin into a number of particles which appear on the work as specks. This condition can be overcome by straining the coating and by taking care to store it in completely filled containers.

Skins:

1. Colloquial term for tires.
2. A covering (usually plastic) for skis on a snowmobile.

Skipping:

A popping feeling in a bicycle drivetrain when you pedal hard; it occurs when a cog is worn out and when you install a new chain on worn cogs

Skirt:

1. The portion of the piston below the rings and bosses. It absorbs the thrust caused by the crankshaft as it makes contact with the cylinder wall.
2. A cover for the rear fender cutout.
   Also See:
   fender skirt
   side skirt

Also See:
bumper skirt
fender skirt
piston skirt expanding
piston skirt
rear bumper skirt

Skirt expander:

See piston skirt expander.

Skirt expanding:

See piston skirt expanding

Skirt piston:

See split skirt piston

Skive:

The action of cutting into something or cutting away rubber from an injury in preparation for a section repair.
