<p>A secondary fueling system is provided for the introduction of an alcohol-based secondary fuel into the combustion intake system of a diesel internal combustion engine. The system includes a fuel tank for containing the secondary fuel, a secondary fuel pump for withdrawing secondary fuel from the fuel tank, a regulator receiving the secondary fuel from the secondary fuel pump and supplying the secondary fuel to an injection system, a secondary controller for operating the secondary fuel pump, the regulator, and the injection system for introducing metered amounts of secondary fuel into the combustion intake system. The injection system includes a fuel injector controlled by the controller for regulating the secondary fuel using pulse width modulation control. The system can include an adapter sleeve for mounting to an existing vehicle intake manifold hose.</p> |
