ign-, igni-, ignis-
(Latin: fire, burn)
A Latin palindrome that describes the movement of moths.
It consists of a small, spring-loaded hammer which, when a button is pressed, hits a quartz crystal which produces a spark to ignite the gas. A piezo ignition system creates a spark to light the gas by triggering an impact upon a special crystal. No electric connection is required.
Piezo ignition systems can operate by either a lever, separate push button, or built into the control knob. Only one spark per turn of the knob or press of the button is generated.
This results in an inefficient, rough-running engine.2. Ignition of fuel in an internal-combustion engine before the spark has been generated, causing inefficient operation.
Preignition may be caused by a hot spot in the cylinder.
2. Starting a burning process or a fire again: "After the rain put out the burning of the brush in the field, the farmer was seen reigniting the piles of trash two days later."
3. To make something; such as, a disagreement or problem that was going away become stronger: "The recent food-poisoning scare has reignited the controversy as to what really caused of the recent E. coli (Escherichia coli) in Europe; especially, in Germany."
"There are fears that job losses will reignite a further dissatisfaction by the people."
2. To arouse the passions of or to excite again: "His words caused the re-ignition of hatred for him."
3. The repetition of setting something on fire: "He ignited the brush earlier and it died down, and then, the wind caused the re-ignition of some of the limbs that were not completely burned."
- An air-fuel mixture is drawn into the cylinder and compressed.
- Heat transfer is added by the spark ignition of the fuel mixture in the cylinder.
- The gases produced by this combustion expand to move the piston downward for the power stroke.
- The burned gases in the cylinder are expelled.
Named after Nikolaus August Otto (1832-1891), a German engineer and inventor.
