Piston engine problem Brisbane - BURNT OUT
Pistons are generally produced from High quality aluminium alloy containing small and varied amounts of copper, magnesium, nickel, titanium and lead depending the intended use of the piston. These high grade alloys are very durable and under normal combustion temperatures and engine loads the pistons will perform correctly for many kilometres. Being a soft metal once the piston is subject to extreme abnormal combustion temperatures the resultant damage to the piston crown will appear as if it was melted with a blow torch.(as in the photo above) The piston will suffer without damage to a point but once the material starts to burn away the already abnormal extreme temperatures will quickly rise being increased rapidly by the actual combustion of the piston material. Overloading an engine coupled with poor cooling, over advanced ignition timing, lean petrol mixtures, incorrect spark plugs, extreme vacuum leaks and over boosted turbo's can create a situation where the pistons starts to melt down and self combust. Once this action happens the problem turns quickly terminal destroying the engine. Diesel engines suffer from similar failures caused by super heated combustion. The primary causes in a diesel is slightly different as faulty injector pump, timing and injectors presenting a rich mixture will generate extreme combustion temperatures that can result in piston burn out.
