Electronic ignition allows a spark plug to be fired at precisely the right time, for the right length of time and with the energy to optimize the power and efficiency of the combustion event.
Alongside the two valves is also a spark plug - an electrically-controlled device that causes a spark and sets fire to the fuel, thus powering the vehicle.
NGK, a spark plug manufacturer, has decided to start producing battery technology to prepare for a future without internal combustion engines.
In addition, a diode laser sensor has been successfully used for crank-angle resolved point measurements of the temperature near a spark plug [8].
[USPRwire, Tue Feb 03 2015] A spark plug is an integral component in an engine, and it performs an important function of producing sparks that are necessary to ignite the mixture of air and fuel in the engine.
A spark plug boot made of this silicone always has the same properties, whatever the temperature to which it is exposed in practice.
They may want a spark plug with a hotter spark, or one that sits farther down in the combustion chamber to produce the precise shape, size and duration of flame they're looking for in there.
* Use a spark plug socket wrench to remove the spark plug.
(In effect, it looks somewhat like a Tesla coil-and interestingly enough, Nikola Tesla held a patent for a spark plug.) This increases your odds of more thorough ignition, even when the probability is reduced.
When the spark generated by a spark plug grows during combustion with the air-fuel mixture, it loses heat when it comes into contact with electrodes and ignition performance decreases.
And the laser beam will be delivered to the combustion chamber through a fibre optic cable, requiring less space than a spark plug and so allowing bigger, more efficient, engine valves needed for better combustion.
Even if you aren't mechanically inclined, before calling a mechanic, carefully remove a spark plug (you'll need a special spark plug wrench for this) and situate it so the hexagonal portion of the plug and engine block are in contact.
A spark plug will be offered to all exhibitors and visitors through the Classic Motor Show website (www.necclassicmotorshow.co.uk) as a trade in exchange for another item that is twice the value and has a link to motoring.
