If this was not enough, many consumers go to extensive lengths to find most up-to-date ringtones and screensavers. Consequently, a myriad of websites now exist specifically to cater for this growing market. Examples include 1st Choice Ringtones (http://www.1st-choice-ringtones.co.uk) and Mobile Ringtonez http://www.mobileringtonez.com." Modern consumers are no longer satisfied with traditional "ring ring". Downloadable tones can range from classical music to latest chart toppers. The public have generally responded positively to such a vast selection, with exception of "crazy frog" which is first ringtone to make it into UK singles chart (and receive several hundred complaints) due to a very aggressive television advertising campaign. The kids apparently love it, but not everyone is happy!

The mobile phone industry is certain to continue evolving, with some research suggesting that one day phones will take place of credit cards and remote control. The innovation and level of competition in mobile music and mobile phone markets can only mean greater choice and lower competitive prices, so sit back and look forward to exciting surprises key players in this industry have to offer us!

All sliding parts can become a hotspot whenever there is insufficient lubrication to reduce friction, probably during starting of engine or any abnormal interruption in force lubrication oil system.

Next, use of fuel oil in engine. Dripping fuel injectors will result in incomplete combustion of fuel above piston top. If dripping is serious, liquid fuel can find their way through piston rings aided by high pressure of combustion process to eventually find its way into crankcase. For trunk type engines, this is a direct path to crankcase. It can become a source of low flash point fuel when mixed with lubricating oil!

For dripping fuel injectors, it is common to find unburnt carbon that will cause piston rings to stick within their grooves, thus destroying sealing function of piston rings. This will not only cause fuel to drip through, but can also cause fire from combustion space to blow past through gaps between piston rings and cylinder bore. This can be a source of heat!

There are other conditions favorable to cause an explosion, for example quality of oil and effects of oxidation after a long period of use, generation of oil mist due to agitation of oil spray, property of oil, etc.

It is impossible to guarantee that any engine will operate for whole of its life without, somewhere, at some time, a hot spot appearing. Therefore it is essential that should a hot spot occur and if it goes undetected, an explosion will not result.

That could be subject of another article... Meanwhile procuring hard-to-find tools is just as important for making engine adjustments.
