What is Pre-Combustion?

The Pre-Combustion system is found mainly on the diesel engines. It uses a classic injection pump, that contains pistons which main function is to push the fuel to the tubing, separate for each engine cylinder, where the fuel enters a nozzle (one for each cylinder) and they pulverized the fuel into the Pre-Combustion Chambers mounted on the engine head. It's on the Chamber where the combustion begins. The combustion comes out as fire from the PreChamber into the cylinder. There are incandescence plugs or heaters mounted on the Pre-Combustion Chambers that heat the air in order to get a better engine ignition.

Damage caused by Pre-Combustion Chamber wear.

The Pre-Combustion Chambers in diesel engines suffer extreme changes in their structures, and with time they tend to crack, they sink below the engine's head's surface, and they also get loose. Due to constant air-fuel combustion's they wear, and sometimes they crack, and if they are not change they can damage the engine's block surface. This happens because if they are loose when there is an explosion  the PreChamber hit the block's surface, causing damage.

Abnormal Combustion Due To Crack on the Pre-Combustion Chambers.

When there is a combustion inside a crack Pre-Combustion Chamber, it sometimes leaks some of the fire from the crack to the cylinder creating abnormal combustion due to Non Uniform Flames.

Installation of the Pre-Combustion Chamber.

When Pre-Combustion Chambers are installed they should be above the head's surface, about 0.001" to 0.003", this is necessary to compensate for the head gasket thickness, in order to avoid, damaging it.
