System and Method for Accommodating Nitrous Oxide in Conventional Engine ECUs

Abstract

A nitrous oxide (N.sub.2C) air intake control module for conventional vehicle engines is disclosed. The invention essentially being comprised of a plugin module that masks the engine's existing cold air intake temp sensor data being sent to the engine control unit (ECU) to accommodate N.sub.2O injection systems. Said device lowering engine emission timing to accommodate the higher N.sub.2O temperatures thereby enhancing the ignition and combustion sequences normally designed for gasoline. An object of the invention is to prevent early detonation or pre-ignition (due to higher temperatures associated with the use of N.sub.2O) thereby maintaining the benefit of increases in power while minimizing excessive wear on an engine

DETAILED DESCRIPTION OF FIGURES

[0016] In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right and other such terms refer to the device as it is oriented and appears in the drawings and are used for convenience only; they are not intended to be limiting or to imply that the device has to be used or positioned in any particular orientation.

[0017] FIG. 1 shows a perspective view of invention 1 comprised of box-shaped, case 2 (being made of a rigid, material such as bur nor limited to plastic, metal and the like) having two parts being affixed together by means of fasteners and having light emitting diode (LED) thereon. Invention 1 housing a control unit (to be introduced further in this document) therein and having wiring harness 4 comprised of power lead 5, ECU connection 7 and intake engine sensor 6 extending from distal ends of said case 2.

[0018] FIG. 2 illustrates a side view of invention 1 installed on a conventional engine 15. In certain embodiments, power lead 5 connecting to the vehicles 12 volt battery power source. ECU connection 7 configured to engage conventional engine ECU harnesses allowing temperature signals to be replaced therein, and engine sensor 6 being connected to an engine's existing, conventional temperature sensor.

[0019] FIG. 3 shows a wiring diagram of invention 1's control unit 26 with voltage supply source 11 energizing SPDT relay 8 and LED 10 and thereby activating switching inside said relay. Said switching allowing invention 1 to alter temperature signal coming from temperature, sensor 12 by means of resistor 13 and sending new temperature signal (such as but not limited to 200 degrees Fahrenheit and the like) to the engine ECU by means of ECU connection 7. The aforementioned control unit also being grounded by means of chassis ground 9.

[0020] FIG. 4 shows a representative view of the invention process with a user activating the device and energizing the control unit in step 15 thereby lighting LED in step 24, energizing N.sub.2O solenoid in step 16, allowing the relay to bypass an engine's existing temperature circuit in step 17 and causing the resistor to generate a higher temperature reading for the engine's ECU. The new signal being sent to engine ECU in step 19 and adjusting ignition timing in step 20. The resulting change in engine timing also decreasing ignition timing in step 21, and increasing cylinder pressure in step 22 and cylinder temperature in step 23 as N.sub.2G is introduced into engine in step 24. The result of these steps culminating in increased engine horsepower in the final step 25.

[0021] It is additionally noted and anticipated that although the device is shown in its most simple form, various components and aspects of the device may be differently shaped or slightly modified when forming the invention herein. As such those skilled in the art will appreciate the descriptions and depictions set forth in this disclosure or merely meant to portray examples of preferred modes within the overall scope and intent of the invention, and are not to be considered limiting in any manner. While all of the fundamental characteristics and features of the invention have been shown and described herein, with reference to particular embodiments thereof a latitude of modification, various changes and substitutions are intended in the foregoing disclosure and it will be apparent that in some instances, some features of the invention may be employed without a corresponding use of other features without departing from the scope of the invention as set forth. It should also be understood that various substitutions, modifications, and variations may be made by those skilled ill the art without departing from the spirit or scope of the invention.
