  2. Fire point - Wikipedia

    en.wikipedia.org/wiki/Fire_point

    The fire point, or combustion point, of a fuel is the lowest temperature at which the liquid fuel will continue to burn for at least five seconds after ignition by an open flame of standard dimension. [1] At the flash point, a lower temperature, a substance will ignite briefly, but vapour might not be produced at a rate to sustain the fire ...

  3. Flash point - Wikipedia

    en.wikipedia.org/wiki/Flash_point

    The fire point is the lowest temperature at which the vapors keep burning after the ignition source is removed. It is higher than the flash point, because at the flash point vapor may not be produced fast enough to sustain combustion. [ 2 ]

  4. Autoignition temperature - Wikipedia

    en.wikipedia.org/wiki/Autoignition_temperature

    The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. [1]

  5. Flame detector - Wikipedia

    en.wikipedia.org/wiki/Flame_detector

    A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.

  6. Cleveland open-cup method - Wikipedia

    en.wikipedia.org/wiki/Cleveland_open-cup_method

    The lowest temperature at which a small test flame passing over the surface of the liquid causes the vapor to ignite is considered the chemical's flash point. This apparatus may also be used to determine the chemical's fire point which is considered to have been reached when the application of the test flame produces at least five continuous ...

  7. Contact breaker - Wikipedia

    en.wikipedia.org/wiki/Contact_breaker

    Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines. The switch is automatically operated by a cam driven by the engine.

  8. Smoke detector - Wikipedia

    en.wikipedia.org/wiki/Smoke_detector

    Fire detection products have the European Standard EN 54 Fire Detection and Fire Alarm Systems that is a mandatory standard for every product that is going to be delivered and installed in any country in the European Union (EU). EN 54 part 7 is the standard for smoke detectors. European standards are developed to allow free movement of goods in ...

  9. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
