The ignition temperature of a given substance is the measure of the minimum temperature at which the substance ignites, without the presence of an external spark or flame. Because of the fact that the material auto-ignites at this temperature range, it is also referred to as the substance's auto-ignition temperature.Know More
The ignition temperature of a substance is a direct rating on the hazards which accompany it; substances that include ether and certain solvents, as just two examples, have low ignition temperatures and are easily ignited by just the radiant heat from sources as innocuous as steam pipes. According to Random House Dictionary, ignition temperature is the temperature at which a substance undergoes spontaneous combustion. Higher ignition temperature ranges are typically indications of a safer substance, in terms of ignition from temperature alone. However, these ranges are only guidelines. Under the right conditions, the ignition temperatures of various substances do change, and these changes are potentially significant.
The ignition temperature is of particular interest to engineers and to industry as a whole, because of the applications within environments where dust, gas and volatile liquids combine with high temperatures. Dust and gas accumulation are both prime concerns, since the right combination of these factors creates the potential for violent explosions.Learn More
Although there are a number of suggested tests for the ignition coil while it is still attached to a car, the only accurate way of testing a coil is on a bench using a multimeter in the resistance setting. The ignition coil has two coils of wires, called windings. The meter quickly displays if either winding is bad.Full Answer >
An ignition coil is a coil in a car's ignition system that carries the 6 or 12 volts from the battery to the many volts used to spark the spark plugs in the ignition. An ignition coil is also called a spark coil, and is classified as an induction coil. All induction coils are electronic transformers that transform low-voltage pulses from the DC supply into higher voltage currents needed to spark machine engines.Full Answer >
Signs of a bad ignition switch could include dashboard lights that come off and on, problems with the vehicle starting and a switch that is hot to the touch. A bad ignition switch can mimic other problems that are seen in a car, such as a faulty motor starter.Full Answer >
Numerous problems with a car can cause a key to get stuck in the ignition. A steering lock that needs a slight turn or is broken can cause a key to get stuck. Dirt or lint blocking the ignition opening, a faulty key or a damaged ignition lock cylinder can also cause this problem.Full Answer >
