  2. Tell-tale (automotive) - Wikipedia

    en.wikipedia.org/wiki/Tell-tale_(automotive)

    The light normally appears when the vehicle ignition is turned on, but the engine is not running, as it detects no oil pressure due to the oil pump not operating (the oil pump is powered off the crankshaft, so only operates when the engine is running). It normally turns off a few seconds after engine start as the oil pump starts working and ...

  3. Cold air intake - Wikipedia

    en.wikipedia.org/wiki/Cold_air_intake

    Most vehicles manufactured from the mid-1970s until the mid-1990s have thermostatic air intake systems that regulate the temperature of the air entering the engine's intake tract, providing warm air when the engine is cold and cold air when the engine is warm to maximize performance, efficiency, and fuel economy.

  4. Dieseling - Wikipedia

    en.wikipedia.org/wiki/Dieseling

    The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. The dieseling phenomenon occurs not just because the compression ratio is sufficient to cause auto-ignition of the fuel, but also because a hot spot inside the cylinder (spark plug electrode ...

  5. Pre-ignition - Wikipedia

    en.wikipedia.org/wiki/Pre-ignition

    Auto-ignition of engine oil droplets (Can be solved by using an oil catch tank) [3] Insufficient oil in the engine; Ignition timing too far advanced; Too much air/too little fuel (octane) to withstand pressures (too much air causes too much pressure for the octane to handle, too little fuel reduces the octane to handle the pressurized air) [5]

  6. Check engine light - Wikipedia

    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 uses 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.).

  7. Carburetor heat - Wikipedia

    en.wikipedia.org/wiki/Carburetor_heat

    Because hot air is less dense than cold air, engine power will drop when carburetor heat is used. Engines equipped with fuel injection do not require carb heat as they are not as prone to icing - the gasoline is injected as a steady stream just upstream of the intake valve, so evaporation occurs as the fuel/air mixture is being drawn into the ...

  8. In Macon, for example, idling is limited to 25 minutes when a car is “being used to supply heat or air conditioning necessary for passenger safety or comfort,” or when temperatures fall below ...

  9. Choke valve - Wikipedia

    en.wikipedia.org/wiki/Choke_valve

    By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally greater amount of fuel to be pushed from the main jet into the combustion chamber during cold-running operation. Once the engine is warm (from combustion), opening the choke valve restores the ...
