Abstract
A method of engine braking includes a initial step of determining whether fuel injector tip temperatures are at or above a pre-determined temperature. If the injector tip temperatures are below the pre-determined temperature, then the electronic control module commands performance of dual event engine braking. If the injector tip temperatures are at or above the pre-determined temperatures, then the electronic control module commands the performance of single event engine braking. Such a strategy can achieve higher overall engine braking horsepower without risking the potential catastrophic dangers associated with injector tip overheating.
