    en.wikipedia.org/wiki/Check_engine_light

    A check engine light or malfunction indicator lamp ( MIL ), is a tell-tale that a computerized engine-management system used to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.). Found on the instrument panel of most ...

  5. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    Using the O2 sensor signal, the ECU can operate the engine with an air–fuel ratio very close to 14.7:1, which is the ideal operating mixture for a three way catalyst to be effective. [2] Robert Bosch GmbH introduced the first automotive lambda sensor in 1976, [3] and it was first used by Volvo and Saab in that year. The sensors were ...

    Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [1] It is derived from ISO 14230-3 and the now obsolete ISO 15765-3 (Diagnostic Communication over Controller Area Network (DoCAN) [2]). 'Unified' in this context ...

  7. Compressed-air car - Wikipedia

    en.wikipedia.org/wiki/Compressed-air_car

    A compressed-air car is a compressed-air vehicle powered by pressure vessels filled with compressed air. It is propelled by the release and expansion of the air within a motor adapted to compressed air. The car might be powered solely by air, or combined (as in a hybrid electric vehicle) with other fuels such as gasoline, diesel, or an electric ...

  8. Secondary air injection - Wikipedia

    en.wikipedia.org/wiki/Secondary_air_injection

    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. Air is delivered under light pressure to the injection point(s). A check valve prevents exhaust forcing its way back through the air injection system, which would damage the pump and other components.

  9. Mass flow sensor - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_sensor

    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.
