| Abstract: |
A novel fuel pretreater apparatus and method for pretreating alternate fuel (63) to render it usable as the fuel source for an internal combustion engine (20). The apparatus includes a volatilization chamber (12) into which the alternate fuel is received. An exhaust plenum (17) encloses the volatilization chamber so that thermal energy supplied by exhaust from the internal combustion engine can be used to volatilize the alternate fuel. A bypass stream of exhaust is diverted through the alternate fuel in the volatilization chamber and is used to carry the volatilized fuel through a reactor prior to its being introduced into the internal combustion engine. The reactor is interposed in the exhaust conduit and is prepared from a reactor tube having a reactor rod mounted coaxially therein in spaced relationship. The exhaust passing through the exhaust conduit provides thermal energy to the reactor to pretreat the alternate fuel.

+ FUEL PRETREATER. APPARATUS AND METHOD
+ Background
+ Field of the Invention This invention relates to internal combustion engines and, more particularly, to a novel fuel pretreater apparatus and method for making it possible for an internal combustion engine to utilize as a fuel a combustible material not otherwise considered suitable as a fuel such as crude oil, used cleaning solvents, recycled oil, used paint thinners, and the like.
The Prior Art The internal combustion engine has been in existence for over 100 years and has been the subject of numerous patents relating to various aspects of its design, operation, etc. A significant proportion of these patents relate to the fuel system particularly as to the handling, vaporization, and distribution of the fuel into the respective combustion chamber of the internal combustion engine. In light of the extreme sophistication of the current trend in internal combustion engines, not only for fuel economy but also for reduction in the emitted pollutants, great care is taken in the selection of the fuel grade particularly as to its quality prior to its
+ Detailed Description of the Prefe red Embgdiment The invention is best understood from the following description and the appended claims taken in conjunction with the accompanying drawing wherein like parts are designed by like numerals throughout.
General Discuss-ion The present invention is a unique apparatus and method for pretreating fuel for an internal combustion engine, the pretreatment making it possible for the internal combustion engine to utilize as its fuel source fuels that are generally considered as not being suitable fuels for an internal combustion engine. These alternate fuels include almost any liquid hydrocarbon such as crude oil or recycled materials such as motor oil, solvents, paint thinners, and various alcohols, to name several. Importantly, the alternate fuel is volatilized and then subjected to a high temperature environment prior to its being introduced into the intake system of the internal combustion engine. Currently, it is not known precisely what happens to the volatilized alternate fuel in this high temperature environment although one speculation is that the larger molecules are broken down into smaller molecular subunits of the heavy molecules.
+ Detailed Description Referring now to Figure 1, the novel fuel pretreater apparatus of this invention is shown generally at 10 and includes a volatilization chamber 12 and a fuel pretreater section 14 incorporated into an exhaust conduit 16. Volatilization chamber 12 is enclosed in an exhaust plenum 17 through which a stream of exhaust 18 passes. Exhaust 18 is produced by an internal combustion engine 20 which can be any suitable internal combustion engine ranging in size from a small, one-cylinder internal combustion engine to a large, multicylinder internal combustion engine. Internal combustion engine 20 is shown herein schematically particularly since no claim is made to an internal combustion engine, per se, only to the novel fuel pretreater apparatus 10 shown and claimed herein.
Internal combustion engine 20 includes a fuel tank 22 which supplies a starting fuel 24 and has a valve 26 for controlling the flow of fuel 24 through a fuel line 28 into an intake manifold 29. Fuel 24 enters internal combustion engine 20 through an intake manifold 29 either through carburetion or fuel injection (not shown) , both of which are conventional systems for introducing fuel 24 into internal combustion engine 20 and are, therefore, not shown herein but only indicated schematically through the depiction of intake manifold 29. Fuel 24 is ordinary gasoline and provides the necessary starting fuel for internal combustion engine 20 until sufficient thermal energy has been produced in order to sustain the operation of volatilization chamber 12 and pretreater section 14. Thereafter, valve 26 is closed and internal combustion engine 20 is operated as will be discussed more fully hereinafter. Internal combustion engine 20 produces exhaust 18 which is collected from internal combustion engine 20 by an exhaust manifold 30. Exhaust 18 is then directed through exhaust conduit 16 into fuel pretreater 10 where it provides the necessary thermal energy for the operation of fuel pretreater 10.
