Piston engine problem Brisbane - HOLE

Piston crowns are extremely durable and if a hole in a piston is caused by the entry of a foreign object it will need to be rather large. The ingestion of small objects like small screws, washers or carburettor parts generally remain embedded into the piston crown. However large objects like valves will easily hole the piston crown and even the block cylinder wall. (see photo's Above) Most piston crowns that present with a hole burnt through are on high performance or race petrol engines. Lean air fuel ratio is the common cause. Methanol race engines run An air fuel ratio of around 5.5 to 1(That is 5.5parts of air to 1 part of methanol) while Petrol road cars run 14.7 to 1 AFR. If a methanol race engine runs lean under race conditions within as little time as 10 seconds it can result in a large hole being burnt through the piston crown. Extremely abnormal combustion temperatures are required to cause this damage so correct Air Fuel Ratio on any engine is so very important.
