ISUZU 4BE1 Engine Piston 8-94438-989-1 5-12111-022-0

he main function of the piston is to withstand the gas pressure of the cylinder, and pass this force to the connecting rod through the piston pin to promote the Crankshaft rotation, it passes the pressure of the combustion gas to the crankshaft, so that the crankshaft rotates and outputs power; The top of the piston also forms the combustion chamber together with the cylinder head and cylinder wall.

The Engine piston is mainly used in internal combustion engines. An internal combustion engine is a device that converts chemical energy into mechanical energy, in which an engine is a type of internal combustion engine. The piston in the engine is another name for the Engine Piston, which is one of the important components of the internal combustion engine.

What Causes Damage to Engine Piston Parts?

So that you can take action before any damage affects the engine, we’ve compiled a list of the most common and specific causes of piston damage to ensure you can easily recognise the problem. 
Common Causes of Piston Damage 

1. Burned Piston
A burned piston can be seen instantly once the top of the engine has been removed. You should be able to recognise visible signs of melting and sometimes a burnt hole in the piston. A burned diesel piston is generally caused by dirty fuel injectors being used.

2. Cracked Piston
Cracked piston causes can include continued use of low-quality fuel. Or, a cracked piston can be a result of the failure of the exhaust gas recirculation system.

3. Snapped Timing Belt
The timing belt plays a key role as it keeps the movement of the pistons and the valves in perfect alternating time. Once the belt has snapped, it can cause a collision between the two which can then lead to further damage. To prevent the timing belt from snapping, it’s important to change the timing belt according to the car manufacturer’s instructions.
