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 about Car Parts & Maintenance
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 interlock device is a piece of equipment installed in a vehicle into which the driver must breathe before he can start the vehicle. If the device detects a blood alcohol level above a certain limit on the driver's breath, the car does not start.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 >
Several tests can be done to test an electronic ignition coil, including a standard coil test, primary circuit switching test and ignition coil resistance. These tests will test the resistance felt on the ignition coil when it is connected to an outside power source.Full Answer >
