Injector cup for Terex TR-100

The injector cup, identified by part number 3042713, serves as a housing and seal for the fuel injector within the engine cylinder head. It creates a thermal and mechanical barrier that protects the injector from the high temperatures and pressures present inside the combustion chamber. By ensuring the injector remains correctly positioned, this component supports the precise atomization of fuel required for efficient engine operation.

This component is compatible with the Terex TR-100 rigid haul truck. It is designed to seat within the cylinder head, often utilizing seals or washers to maintain a hermetic environment that prevents combustion gas leakage. Proper installation is necessary to avoid loss of compression, injector overheating, or potential damage to the cylinder head assembly.

In diesel engine systems, injector cups facilitate the transfer of heat away from the injector nozzle while isolating the fuel delivery system from the harsh internal environment of the cylinder. Maintaining the integrity of these cups is important for preventing engine performance issues and ensuring that the combustion process remains consistent under various operational loads.
