Causes of overheated piston

  • Inadequate or failure of coolant supply and excessive deposit in cooling gallery.  
  • Continued overload operation  
  • Unbalanced cylinder load 
  • Incomplete combustion owing to loss of compression, faulty fuel timing, unstable fuel and insufficient charge air.  
  • High friction on liner owing to failure of lubrication, faulty rings conditions, long skirt touching the liner due Misalignment of piston and distorted liner 
  • Late ignition faulty fuel timing  
  • Excessive water content in fuel.  
  • Faulty rings conditions causing blow-by  
  • Long skirt touching the liner due Misalignment of piston and distorted liner  
  • Excessive deposit in cooling gallary
