GENERAL INFORMATION
GLOSSARY
Air Valve Vacuum (AVV)
The vacuum signal taken from below the air
valve assembly and above the throttle butterfly
valve.
ADP
Adaptive Digital Processor.
Air/Fuel Ratio
The amount or balance of air and fuel in the air
fuel mixture that enters the engine.
Analog Voltmeter
A meter that uses a mechanical needle to point
to a value on a scale of numbers. It is usually of
the low impedance type and used to measure
voltage and resistance.
Aromatics
Pertaining to or containing the six-carbon ring
characteristic of the benzene series. Found in
many petroleum distillates.
Backfire
Combustion of the air/fuel mixture in the intake
or exhaust manifolds. A backfire can occur if the
intake or exhaust valves are open when there is
a mis-timed ignition spark.
Benzene
An aromatic (C
6
H
6
). Sometimes blended with
gasoline to improve anti-knock value. Benzene
is toxic and suspected of causing cancer.
Bi-Fueled
A vehicle equipped to run on two fuels.
Blow-By
Gases formed by the combustion of fuel and air,
which ordinarily should exert pressure only
against the piston crown and first compression
ring. When rings do not seal, these gases
escape or “blow by” the side of the piston into
the crankcase.
BTU
British Thermal Unit. A measurement of the
amount of heat required to raise the tempera-
ture of 1lb. of water 1 degree F.
Butane
An odorless, colorless gas, C
4
H
10
found in natu-
ral gas and petroleum. One of the five LP gases.
CAFE
Corporate Average Fuel Economy.
CARB
California Air Resources Board.
Carbon Monoxide (CO)
A chemical compound of a highly toxic gas that
is both odorless and colorless.
Carburetor
An apparatus for supplying an internal-combus-
tion engine a mixture of vaporized fuel and air.
Cathode Ray Tube
A vacuum tube in which cathode rays usually in
the form of a slender beam are projected on a
fluorescent screen and produce a luminous
spot.
Circuit
A path of conductors through which electricity
flows.
Closed Loop Operation
Applies to systems utilizing an oxygen sensor. In
this mode of operation, the system uses oxygen
sensor information to determine air/fuel ratio.
Adjustments are made accordingly and checked
by comparing the new oxygen sensor to previ-
ous signals. No stored information is used.
CNG
Compressed Natural Gas.
CKP
Crankshaft Position Sensor

1-2
1 — GENERAL INFORMATION
CMP
Camshaft Position Sensor
Conductor
A material, normally metallic, that permits easy
passage of electricity.
Contaminants
Impurities or foreign material present in fuel.
Control Module
One of several informal names for a solid state
microcomputer which monitors engine condi-
tions and controls certain engine functions; i.e.
air/fuel ratio, injection and ignition time, etc. The
formal name and the one used throughout this
manual is ECM, or Engine Control Module.
Converter
A LPG fuel system component containing vary-
ing stages of fuel pressure regulation combined
with a vaporizer.
Cryogen
A refrigerant used to obtain very low tempera-
tures.
Current
The volume or flow of electrons through a con-
ductor. Measured in amperes or amps.
DBW
Drive By Wire
Dedicated Fuel System
A motor fuel system designed to operate on only
one fuel type.
Diaphragm
A thin, flexible membrane that separates two
chambers. When the pressure in one chamber
is lower than in the other chamber, the dia-
phragm will move toward the side with the low
pressure.
Diaphragm Port
The external port located at the fuel inlet assem-
bly and connected to the vacuum chamber
above the air valve diaphragm.
DLC
Data Link Connector.
DVOM
Digital Volt/Ohm Meter . A meter that uses a
numerical display in place of a gauge and is
usually of the high impedance type.
DTC
Diagnostic Trouble Code
DST
Diagnostic Scan Tool.
DVOM
Digital volt/ohmmeter.
ECT
Engine Coolant Temperature.
ECM
Electronic Control Module
ECOM
A DLC cable supporting CAN and serial com-
munication with a Spectrum II or III ECM.
EFI
Electronic Fuel Injection. A fuel injection system,
which uses a microcomputer (ECM) to deter-
mine and control the amount of fuel, required by,
and injected into, a particular engine.
EGO
Exhaust Gas Oxygen, used to describe a sen-
sor. Also known as “HEGO” (Heat Exhaust Gas
Oxygen) sensor, “O
2
” or “Oxygen sensor.
EGR
Exhaust Gas Recirculation.

fermenting starch or sugar.
Evaporative Emissions Controls
An automotive emission control system
designed to reduce hydrocarbon emissions by
trapping evaporated fuel vapors from the fuel
system.
Excess Flow Valve
A check valve that is caused to close by the fuel
when the flow exceeds a predetermined rate.
FTV
Fuel Trim Valve.

atmosphere to trap heat and cause global
warming.
HC
Hydrocarbon. An organic chemical compound.
HD 10
A fuel of not less than 80% liquid volume pro-
pane and not more than 10% liquid volume pro-
pylene.
HD 5

and carbon (HC). Gasoline and almost all other
fuels are hydrocarbons.
Hydrostatic Relief Valve
A pressure relief device installed in the liquid
propane hose on a propane fuel system.
IAT

Ideal Mixture
The air/fuel ratio at which the best compromise
of engine performance to exhaust emissions is
obtained. Typically 14.7:1.
Ignition Reserve
The difference between available voltage and
the required voltage.
ILEV
Inherently Low Emission Vehicle.
IMPCO
Imperial Machine Products Company.
IMPCO Technologies, Inc.
A manufacturer of both LPG and Gasoline fuel
systems.
Impedance
A form of opposition of AC current flow (resis-
tance) measured in ohms.
Insulation
A nonconductive material used to cover wires in
electrical circuits to prevent the leakage of elec-
tricity and to protect the wire from corrosion.
Intercept
An electrical term for a type of splice where the
original circuit is interrupted and redirected
through another circuit.
ITK
IMPCO Test Kit
Knock
Sound produced when an engine’s air/fuel mix-
ture is ignited by something other than the spark
plug, such as a hot spot in the combustion
chamber. Also caused by a fuel with an octane
rating that is too low and/or incorrect ignition
timing. Also called detonation or ping.
Lambda Sensor
A feedback device, usually located in the
exhaust manifold, which detects the amount of
oxygen present in exhaust gases in relation to
the surrounding atmosphere.
LDV
Light Duty Vehicle.
Lean Mixture
An air to fuel ratio above the stoichiometric ratio;
too much air .
LEV
Low Emission Vehicle.
Limp-in or Limp Home
A mode where the ECM or a component has
failed, but the vehicle remains operational
although the engine may operate minimally. This
term may also describe the drivability character-
istics of a failed computer system.
