Our invention is new to the art of fuel injection because it enables the fuel injection system to evaluate the properties of the fuel in the system and then choose a base line fuel injection map from a group of maps. This chosen map will be more accurate or a better match to the fuel that is going to be injected. By choosing a map that matches the properties of the fuel that is about to be injected you will have a more precise amount of fuel injected and their by have better fuel economy better power output and lower emissions. The present invention addresses the above and other needs by providing a method and system to achieve better fuel economy, lower emissions and better performance, than is available in today's fuel injection systems. As disclosed herein, after one or more sensors evaluates the fuel, the control module will choose a base line fuel injection map from a group of maps to more accurately meter and inject the fuel being delivered. This system will work in conjunction with existing fuel injection technologies that are common to anyone skilled in the field of fuel injection. The above-identified methods and systems be utilized alone or in conjunction with other fuel system controlling techniques. additionally, each of the specific steps involved in the processes, described herein are easily modified or tailored to meet the peculiar design and operational requirements of the particular engine and the anticipated operating environment in which the engine is used. From the foregoing, it should be noted that the invention provides a method and system for the detection of fuel used in an electronically controlled engine. While the invention disclosed herein has been described by us to the best of our ability, numerous modifications and variations can be made thereto by those skilled in the art without departing from the scope of the invention as set forth in the claims or sacrificing all its material advantages.
A fuel injection system of a motorized vehicle that has on board the vehicle and inside the fuel system a sensor or bank of sensors that continuously reads the properties of the fuel in the system. The properties to be read would include but not be limited to:
A fuel injection system of a motorized vehicle that has a control module with multiple maps (1 to infinity) of fuel injection curves to choose from. When prompted by incoming information this control module will choose a map, from the selection of maps, that correlates to the incoming information.
A fuel injection system of a motorized vehicle that has on board the vehicle and inside the fuel system a sensor or bank of sensors that continuously reads the properties of the fuel in the system. The properties to be read would include but not be limited to:
