Abstract
An electronic fuel injection augmentation system and method for a turbocharged diesel engine compression braking system injects a predetermined volume of fuel into cylinders of an engine at a predetermined timing prior to the piston of the cylinder reaching a top dead center position. Combustion of such injected fuel increases cylinder pressure and engine braking. The increased pressure is transferred to the turbocharger of the engine thereby increasing intake air flow and engine braking as a result thereof.
