Pumped air injection systems use a vane pump called the air pump, AIR pump, or colloquially "smog pump" turned by the engine via a belt or electric motor.The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system.
The Chevrolet Cruze is a compact car produced by General Motors from 2008 through 2023. It was designated as a globally developed, designed, and manufactured four-door compact sedan, complemented by a five-door hatchback body variant from 2011, and a station wagon in 2012.
An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. [1] It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman. [1]
ALDL 12 pins connector - front view. Assembly Line Diagnostic Link, Assembly Line Data Link, or ALDL is a proprietary on-board diagnostics system developed by General Motors before the standardization of OBD-2.
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
The term also refers to the removal of molecular oxygen (O 2) from gases and solvents, a step in air-free technique and gas purifiers. As applied to organic compounds, deoxygenation is a component of fuels production as well a type of reaction employed in organic synthesis , e.g. of pharmaceuticals .
Composition of normal air vs. hypoxic air. Hypoxic air technology for fire prevention, also known as oxygen reduction system (ORS), is an active fire protection technique based on a permanent reduction of the oxygen concentration in the protected rooms.
The oxygen sensor is the basis of the closed-loop control system on a spark-ignited rich-burn engine; however, it is also used for diagnostics. In vehicles with OBD II, a second oxygen sensor is fitted after the catalytic converter to monitor the O 2 levels. The O 2 levels are monitored to see the efficiency of the burn process. The on-board ...
