Glossary:
ACT:Air Charge Temperature sensor (SEE IAT). Used in prior veichles of 1992.
AT: Automatic Transmission
ATX: Automatic Transaxle
ATF:Automatic Transmission Fluid (also used in Power Steering and Manual gear box!)
BDC: Bottom Dead Center
BTDC: Before Top Dead Center
CEL: Check Engine Light (see MIL)
CKP: Crankshaft Position Sensor
CMP: Camshaft Position Sensor
CPS: Old term (that I still use...) Camshaft Position Sensor (Now CMP, see above)
Detonation: (see Pinging)
DIS: Distributorless Ignition System
DOHC: Dual OverHead Cam. Engine design in which pushrods are no longer used- Instead, 2 cams sit on top of the valve assembly and the cam lobes push down on the RFFs, causing the valve to open. A more efficient design, can take more revs, but lacks the pushrod "punch" you may hear about.
DPFE: Differential Pressure Feedback EGR. This sensor detects pressure differential across two points on the EGR feed tube to ensure the proper operation of the EGR valve. Common cause of "EGR flow Insufficient" or "EGR flow excessive" CELs.
E/C: Extended Cab (see S/C)
ECU: Engine Control Unit. The vehicle's main engine computer
EDIS: Electronic Distributorless Ignition System (Same as DIS)
EEC: (EEC-IV pre-'95, EEC-V post-'95) Pronounced "EEK", Electronic Engine Control
EGR: Exhaust Gas Recirculation. Valve that allows the engine to control cold emissions and to moderate pinging in the event of cylinder overtemperature
EVR: EGR (see above) Vacuum Regulator. It's an electromagnetic solenoid that controls gas flow to the EGR valve. Looks like a Ranger clutch reservoir with an electrical connection and two vacuum fittings on the bottom.
FAQ: Frequently Asked Questions (You're reading it!)
F/I: Forced Induction. The use of devices (turbo, supercharger, nitrous oxide) to introduce more oxygen into the air/fuel mixture. Turbos and superchargers pressurize the air (more oxygen to burn per unit of volume), nitrous introduces the oxygen from its composition (N2O)
FPR: Fuel Pressure Regulator
FWD: Front Wheel Drive
FHP: Flywheel Horse Power - usually factory specs. Must be computed.
FTQ: Flywheel Torque - usually factory specs.
HP: Horse Power
IAC or IACV: Idle Air Control Valve. Cylindrical valve mounted on the rear of the UIM. Controls idle air flow
I/H/E: Intake/Headers/Exhaust. The most common mods to our engines to net additional power
IAT: Intake air temperature sensor
LIM: Lower Intake Manifold
LSD: Limited Slip Differential
MIL: Malfunction Indicator Light, also called the CEL. The ECU flags this light to come on if it detects an error while the car is in operation
Moosing: "Honking" sound caused by resonance in the vehicle's intake system at idle. Usually caused by a defective or failing IACV
MT: Manual Transmission
MTX: Manual Transaxle
N/A: Natural Aspiration. A non-F/I motor
N2O: Nitrous Oxide, the gas. Also refered to as "Nitrous", NOS® is a brand name (of the Holley® Performance family) and should not be used to discribe a generic N2O system. NO is Nitric Oxide, NO2 is Nitrous Dioxide, different stuff.
OHV: Which is used in the Vulcan motors, it has a single cam placed directly in the middle of our motors. It controls the lifters/push rods that move up and down to open and close the valves on the heads.
Pinging: Sound caused by the premature explosion of the air/fuel mixture, like the sound of a can of spray paint being quickly shaken. Also called detonation, a dangerous condition that can be caused by overheating of the engine, high air temps, poor fuel, or incorrect timing and can lead to cylinder or valve failure
P&P: Port & Polish. Method used to remove material to increase air flow or create smooth surfaces.
PSI: Pounds Per Square Inch
RWD: Rear Wheel Drive
SC: Supercharger
S/C: Standard Cab
SVT: Ford's Special Vehicle Team. Ford's division for specialized higher-performance cars
SOHC: It is same design of DOHC but a single cam placed atop of our heads that open and close our valves, replacing pushrods.
TDC: Top dead center
TPS: Throttle Position Sensor
TQ: Torque
UIM: Upper Intake Manifold
WAF: “Wife Acceptance Factor”. The unknown variable most hobbyists have to determine before the non-automotively inclined significant other will accept a modification of a particular vehicle, normally requiring an explination: "Honey, if I add the sport suspension the car handles much more predictably and it improves vehicle safety”, “The electric fan is quieter and will help us save gas.” etc.
WOT: Wide Open Throttle
WHP: Wheel Horse Power also expressed as RWHP (Rear Wheel HP) or FWHP (Front Wheel HP) to differentiate between vehicle models.
WTQ: Wheel Torque
I recieved some of this information from Boss 3.0's website Rogue Performance (http://www.rogueperformance.com).
This is a guide to helps others have an understanding of phrases that are used within this forum.
Please if there is any i missed please chime in and add some or even correct me. thanks!!
