2. Mass flow sensor - Wikipedia

   en.wikipedia.org/wiki/Mass_flow_sensor

   A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.

3. Chevrolet Suburban - Wikipedia

   en.wikipedia.org/wiki/Chevrolet_Suburban

   For 1972, the optional rear-seat air conditioning was redesigned with a smaller housing (previously fitted with a housing that ran the full length of the roof). The Action-Line Suburban was produced alongside the rapid growth of the recreational vehicle market in the late 1960s. While only about 6,200 Suburbans were produced for 1967, by 1972 ...

4. Chevrolet small-block engine (first- and second-generation)

   en.wikipedia.org/wiki/Chevrolet_small-block...

   In 1994 the LT1 switched to a mass airflow sensor and sequential port injection. A new, more capable computer controlled the transmission as well as the engine and got a new name: Powertrain Control Module (PCM). Where the ECM held its calibration information in a replaceable PROM chip, the 1994-95 OBD1 PCMs are reprogrammable through the ...

5. General Motors LS-based small-block engine - Wikipedia

   en.wikipedia.org/wiki/General_Motors_LS-based...

   The LS6 shares its basic block architecture with the GM LS1 engine, but other changes were made to the design such as windows cast into the block between cylinders, improved main web strength and bay to bay breathing, an intake manifold and MAF-sensor with higher flow capacity, a camshaft with higher lift and more duration, a higher compression ...

6. Air–fuel ratio - Wikipedia

   en.wikipedia.org/wiki/Air–fuel_ratio

   Air-fuel ratio is the ratio between the mass of air and the mass of fuel in the air-fuel mix at any given moment. The mass is the mass of all constituents that compose the air or fuel, whether they take part in the combustion or not. For example, a calculation of the mass of natural gas as fuel — which often contains carbon dioxide (CO 2 ...

7. Filling station - Wikipedia

   en.wikipedia.org/wiki/Filling_station

   These stations typically offered free air for inflating tires, as compressed air was already on hand to operate the repair garage's pneumatic tools. While a few filling stations with a service station remain, many in the 1980s and 1990s were converted to convenience stores while still selling fuel, while others continued to offer services but ...
