MAIN WELL: Describes the reservoir located in the central body casting where fuel for the primary system is stored., connected to the venturi area through a discharge nozzle.
MANIFOLD ABSOLUTE PRESSURE (MAP): Describes a sensor whose role it is to monitor an engine's intake manifold pressure and transmit the data to the engine controller so it can adjust spark timing and fuel mixture.
MANIFOLD PRESSURE CONTROL (MPC): Describes a fuel injection system whose role it is to determine engine load based on intake man pressure
MANIFOLD PRESSURE SENSOR: Describes a sensor whose role is to record pressure changes in the intake manifold related to barometric pressure.
MANIFOLD RUNNER: Describes a single passage in a manifold running from one cylinder to the central manifold opening
NOZZLE DRIP: Describes the situation where air passing through the venturi when it is idling can cause fuel to drip from the discharge nozzle.
NOZZLE RESTRICTOR: Describes a restrictor fitted in the fuel filler neck of cars containing catalytic converters preventing the flow of fuel from leaded petrol pumps.
OXYGENATED GASOLINE: Describes any fuel containing a mixture of ethyl or methyl alcohol, which, with the addition of oxygen, produces a slightly leaner fuel-air blend especially beneficial to older cars.
OCTANE NUMBER: Describes the system that rates every gasoline brand according to its ability to resist knocking.
PETROLEUM: Describes the raw material, mainly consisting of hydrogen and carbon from which gasoline, kerosene, some lubricating oils, propane and diesel fuel, among others, are refined.
PORT FUEL INJECTION(PFI): Describes a type of fuel injection with at least one injector mounted in each cylinder's intake port that improves fuel distribution while allowing greater flexibility in intake-manifold design.
PULSED INJECTION: Describes a system that delivers fuel in intermittent pulses by opening and closing solenoid-controlled injectors.

PUMP-LINE-NOZZLE FUEL SYSTEM: Describes a fuel system using a single injection pump driven off the gear train on the engine's front that also drives the camshaft.

SEQUENTIAL ELECTRONIC FUEL INJECTION (SEFI): Describes a form of computer-controlled fuel system that distributes fuel through an injector located in each engine's intake port.
SHAFT SEAL: Describes a form of seal used to prevent fluid from leaking out between a stationary part and a rotating shaft.
SHAFT SLEEVE: Describes a sleeve designed to protect a shaft from erosion and wear at shaft seals.
SINGLE POINT INJECTION (SPI): Describes fuel-injection system which sprays gasoline under pressure into the intake air at one place, regarded as being less complicated than a multi-point injection system while achieving a higher level of carburation than a standard carburettor.
