Change Of State

The rearrangement of molecular matter as it changes between any of the three physical states solids, liquids, or gases

Channel

1. To lower the body over the chassis. 2. Individual leg of the hydraulic system that relay pressure from the master cylinder to the wheel cylinder.

Chapman Strut

A type of rear suspension having a telescoping strut that is attached to the chassis at the top and to two links at the bottom, restricting lateral and longitudinal movement.

Chapman Strut

A type of MacPherson strut variant used on rear suspension systems. It is named after Colin Chapman, who was the first to employ it, on his Lotus cars.

Characteristic

A measured or observed property of a device or substance.

Charcoal Canister

A container, usually located in the engine compartment, containing activated charcoal. The charcoal absorbs or traps vapors from a vehicle's sealed fuel system, generally when the engine is turned off. This is a basic component of evaporative emissions control systems.

Charcoal Canister

An emissions-reduction device that controls evaporative emissions from a vehicle's gas tank.

Charge

1. To restore the active material in a battery cell by electrically reversing the chemical action of discharge. 2. To fill an air conditioner with a specific amount of refrigerant or oil by volume or weight. 3. The amount of fuel/air mixture to be burned in a cylinder. 4. To drive aggressively.

Charge Temperature Sensor

A sensor that sends a signal to the computer causing it to vary the temperature of the intake stream.

Charge The Trailer

To fill the trailer air-brake system with air.

Charge Time

The amount of time necessary to charge a capacitor

Charge Tolerance

The accuracy, plus/minus, permitted in the specified amount of liquid or gas that is charged into a system.

Charger

1. A term often used to describe a battery charger. 2. A top performance driver; one who pushes his car to the limit.

Charging

1. The act of placing a charge of refrigerant or oil into an air-conditioning system. 2. The act of refreshing a batter.

Charging Circuit

See charging system

Charging Cylinder

A container with a visual indicator, for use when a critical or exact amount of fluid must be measured.

Charging Hose

A small-diameter hose, between the system and source, that is constructed to withstand high pressures.

Charging Station

A unit containing a manifold and gauge set, charging cylinder, vacuum pump, and leak detector used to service air conditioners.

Charging System

A group of electrical components ( battery, alternator, voltage regulator, ) and interconnecting wiring, used to supply system voltage and amperage while charging the battery.

Charging Voltage

The measured voltage of the alternators output
