Beschreibung
Zusammenfassung:	An engine exhaust braking method and apparatus. The method includes injecting a predetermined amount of fuel per stroke into an engine cylinder during engine braking, wherein the predetermined amount of fuel cools the fuel injector nozzle, thereby allowing the engine braking to be performed without damage to the fuel injector nozzle due to excessive heat. The apparatus includes a fuel injector having a nozzle and capable of injecting a predetermined amount of fuel into an engine, and a processor connected to the fuel injector, with the processor monitoring engine operation and capable of causing the fuel injector to inject the predetermined amount of fuel into the engine, wherein a predetermined amount of fuel is injected into the engine to cool the fuel injector nozzle, thereby allowing the exhaust braking to be performed without damaging the fuel injector nozzle due to excessive heat.
