ChaffingUsed to describe the unintentional action of one component rubbing against another. | |
ChamoisA soft suede leather formerly from the skin of the chamois antelope but now more often made from sheepskin. | |
Charcoal CanisterA part of a fuel evaporative (EVAP) system. The charcoal absorbs petrol vapour during fuel tank venting and returns the fuel to a reverse air flow and into the engine under specific conditions. | |
Charge CurrentSee charge rate. | |
ChargingProcess of building up the level of charge in a battery or capacitor. | |
Charging RateThe recommended rate of charge for a battery. Usually one tenth of the amps in the Amp hour rate for one and a half times the hours for a fully discharged battery. | |
ChassisStructural lower part of a vehicle to which the running gear and body are attached. The true chassis is now evident only in larger vehicles. | |
Check ValveA one way valve, using a plate or ball and spring, that permits fluid flow in one direction only. Used in hydraulic systems to retain a residual pressure. | |
CheckingA type of paint film defect in which cracks in the film begin at the surface and progress downward. The result is usually a straight v-shaped crack which is narrower at the bottom than the top. | |
ChecksumA checksum is a count of the number of bits in a transmission unit that is included with the unit so that the receiver can check to see whether the same number of bits arrived. If the counts match, then one can assume that the complete transmission was received. | |
Chemical BondA reaction between atoms that causes a force such as to create a bond. | |
Chemical Cartridge RespiratorA respirator which uses a cartridge containing various chemical substances to purify inhaled air of certain gases and vapours. | |
Chemical StainingSpotty discolouration of the topcoat sometimes caused by environmental conditions (acid rain, tree sap, etc.) It can also be caused by improper activation of body filler which leads to staining in the subsequent layers of topcoat. | |
Chemical TreatmentA process that uses chemical to bring about a change in something. | |
ChipDescription of an integrated circuit where the circuit is built on a silicon chip. | |
ChippingSmall flakes of a finish losing adhesion from the substrate. Usually caused by the impact of stones or hard objects. | |
ChokeA restriction in a carburettor. The term is used to describe either the venturi as in single or twin choke carburettor, or for the cold start device. | |
Choke FlapThe butterfly type valve that restricts the flow of air. | |
Chopper ModuleAn electronic circuit or unit that switches a supply on and off rapidly. | |
ChromaThe level of saturation or intensity and richness of a colour. De-saturated or "dirty" colours have less chroma; saturated or "clean" colours have more chroma. | |
ChromateA chemical compound used as a component in primers to provide corrosion protection to metal. | |
Chromate RinseNewly manufactured vehicle bodies are completely immersed in a chromic acid solution after zinc or iron phosphating to passivate the metal at the base of cracks and pinholes in the phosphate. Chromate rinsing, as used in modern mass-production paint preparation, will greatly increase corrosion resistance. | |
