Abstract
An improved turbocharger system for a diesel engine includes a turbocharger driven by the exhaust gases of the engine. Air is compressed by the turbocharger prior to admission to the engine intake manifold. An auxiliary fuel tank filled with an alcohol and water mixture is pressurized by compressed air from a line connected to the turbocharger outlet. An auxiliary fuel line connects the fuel take to the intake manifold. So long as the auxiliary tank pressure is below a threshold pressure, a control valve maintains the auxiliary fuel line in closed condition. Upon exceeding the threshold pressure, the valve opens and the water and alcohol mixture is driven by an auxiliary pump and injected into the intake manifold. The outlet pressure of the turbocharger controls the initiation and quantity of fuel provided from the auxiliary fuel tank to the intake manifold. Thus, the auxilliary fuel quantity is substantially directly proportional to the work being performed by the engine and is automatically adjusted to compensate for changes in engine loading, speed and torque.
