ROTARY. ENGINE: | In- ternal-combustion engine in which ‘one ‘or more three-- “revolve , in™ sided | rotors. ‘specially shpaed chambers; in every. revolution: each ‘sided of the rotor performs all: the functions of a four- stroke-cycle engine. © ROTOR: Revolving device; ” in the distributor it relays high-voltage ‘current from the coil to the various spark- plug leads. SHIMMY: Undesirable side to side motion of the ‘wheels during driving. SPARK: High-voltage electrical discharge that occurs when current moving ‘through the spark plug -jumps across the gap bet- ween the metal electrodes. SPARK ADVANCE: See advancing the spark. SPARK GAP: Distance between the centre and side electrodes on a spark plug.” SPARK PLUG: Porcelain- insulated metal device that conducts electricity across a gap between its two electrodes to ignite the fuel mixture. - SPARK-PLUG GAPPING: Adjusting a spark plug’s side electrode to alter its distance from the centre electrode. SPEEDOMETER: In- strument that measures the rotation of the drive shaft to indicate driving speed. STROKE: Total distance a piston travels within a cylinder. SUMP: See pan. SYNCHROMESH TRAN- SMISSION: Manual §tran- smission in which all gears are constantly meshed and ratios are selected by moving synchronizing rings. TACHOMETER: In- strument that measures engine speed in revolutions per minute. TAILPIPE: Section of the exhaust system from the muffler to the rear of the car. ; THERMOSTAT: Device used to control the tem- perature of air, gas or liquid flowing'through a system. “Wi | PARTS oa se high-voltage . drives. the ‘camshaft by linkingi it to the crankshaft. TIMING THE IGNITION: Tune-up procedure in which sparkplug firing is adjusted to occur at the correct instant of a given piston’s cycle. TIRE BEAD: Reinforced portion of a tire that holds the tire on the wheel rim. TIRE “PROFILE: Ratio between a tire’s tread-to- bead height and its’ sidewall- to-sidewall width. TIRE ROTATION: Periodic repositioning of tires on different wheels to equalize irregular wear and prolong iread life. TIRE SIDEWALL: Portion of a tire body between the tread and the bead. TOE-IN: Condition in which the distance between the — front wheels of a car is less at their front than at their rear; front wheels normally are aligned to turn in a fraction of an inch. TOE-OUT: Condition in which the. distance between _ the front wheels of a car is greater at their front wheels of a car is greater at their front than at their rear; this 1urning out causes uneven tire wear. TORQUE: Twisting or turn- ing force. TORQUE CONVERTER: Until that transfers and multiplies engine torque in .an, automatic transmission. TRANSMISSION: Gear unit that’ varies the relative speeds of the engine and the driving wheels to produce the proper amount of torque for different driving § situa- lions. TUNE-UP; Process of check- ing. repairing and adjusting various components of the ignition and fuel systems to obtain maximum engine per- formance. TURBINE ENGINE: Internal- combustion ecngine — that utilizes burning gases to drive a turbine, or vaned wheel, which turns a drive shaft. TIMING CHAIN: Chain that | TWO-STROKE-CY CLE ENGINE: _. Engine piston to complete its power- _ producing combustion: cycle. UNIVERSAL JOINT: Flex- ible coupling between two rotating shafts that allows one shaft to be at an angle to the other. V-TYPE ENGINE: Internal- combustion engine in which the cylinders are arranged in two banks at an angle to each other. VALVE: Device used to open and close an aperture, to allow gasses or fluids. to pass. oO VALVE LIFTER: activated by the camshafi to move a_ pushrod, thus causing a valve to open and close. VALVE PORT: Aperture in the cylinder head of engine block opened or closed by either. an intake or exhaust valve. VISCOSITY: Measure of an oil’s thickness and hence its inherent ability to flow. VOLT: Unit of electrical force that will move a current of one ampere through a resistance to one ohm. VOLTMETER: Electrical instrument used to measure voliage in a circuit. WANKEL ENGINE: Rotary engine, designed by German engineer Felix Wankel. WATER JACKET: Passages in the engine block around the cylinder and_ valves through which coolant circu- lates. . WHEEL BALANCE: Distri- bution of weight within a whecl-and-tire assembly; a balanced wheel rotates with- out vibration. WHEEL CYLINDER: Part of a hydraulic drum-brake system that transmits pres- sure from the master cylinder to cause the brake shoes to he moved. WHEELBASE: Distance between the centres of the front and the rear wheels. WORM GEAR: _ Spiral- shaped gear in the stecring box used to engage and drive another gear.
