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
The top reason ignition coils fail is bad spark plugs or plug wires. Another potential cause is heat and vibration, which can damage the ignition coil's windings and insulation. If an engine is experiencing repeated coil failures, the underlying cause may be resistance from worn spark plugs or excessive spark plug gap. In rare cases, the failure may be due to a lean fuel condition caused by leaky valves.Full Answer >
An ignition control module is a component in a vehicle's engine that enables a spark to be produced at the correct time in each cylinder. It does much the same job as contact breaker points did in older cars.Full Answer >
Ignition coil failures are caused by worn out spark plugs that fail to transmit electronic signals in a functional and fluid manner. This creates a disruption in the regular flow of power across the ignition coil and makes the engine lose power. It is less common but still possible that the rotor the ignition coil rests on breaks and reduces the function of the power circuit.Full Answer >
The General Motors ignition switch recall affects a large number of vehicles built between 1997 to 2014, though only certain models are affected in any given year. Vehicles under recall for at least one model year include the Chevrolet Camaro, Chevrolet Impala, Cadillac CTS and Pontiac Grand Am.Full Answer >
