CONTROL METHOD AND APPARATUS FOR USE IN AN ALCOHOL FUELED INTERNAL COMBUSTION ENGINE |
摘要 |
<p>A method for controlling a fuel system of an internal combustion engine. The method is employed with a fuel system having a source of alcohol-containing liquid fuel, at least one fuel injector, a heat source for heating the liquid fuel in the at least one fuel injector, the heat source capable of heating the liquid fuel to a level sufficient to convert at least a portion thereof from the liquid state to a vapor state and a metering valve operable to achieve a range of flow rates characterized by a valve open versus valve closed duty cycle. The method includes the steps of metering a predetermined amount of fuel based on engine operating conditions, controlling power supplied to the heat source of the at least one fuel injector to achieve a target temperature, determining alcohol concentration of the fuel and adjusting the power supplied to the heat source of the at least one fuel injector based on the alcohol concentration determination. A method of determining alcohol concentration and a fuel system for use in an alcohol fueled internal combustion engine is also provided.</p> |
