the satisfactory vaporization of the fuel of internal combustion engines as at present used, by preheating of the air content of the charge. I am aware of the fact that many appliances have been evolved with a similar end in view, such, as a cap enclosing cylinder heads and having an inlet and-carburetor connections, as well as those including conduit elements associated with the exhaust manifold, and that which includes a deck in the upper part of the motor hood with passages therethrough around the cylinders to a lower chamber therefrom which air is drawn by the fly-wheel fan. In these prior dew'ces, however, while a partial benefit is derived from their use, due allowance has not been made for the very great speeds at which air moves therein, and only a partial heating effect is obtained at best. In one well known car having a four-cylinder enine and a one-inch passage from the caruretor, with the engine operating at the speed at which it is rated, the air required to supply the piston displacement would have to move through the manifold stemat the rate of about 20,000 feet per minute, and
even allowing liberally for rarefaction, it must be seen that the gases move at a rate which does not permit the absorption thereby of much heat from heated surfaces over which it may pass in the fraction-of asecond intervening between its entrance to the carburetor and .its leaving the inlet manifold.
While many -rior devices have enlarged passa cs through which the air supply may trave these enlargements are only incidental to the provision of more heating surfaces, nor do they succeed in giving a cubic cappcity to the heating spaces which will have a proper rflation to the rate of absorption of heat by the air. It is in the latter respect that my invention aims to effect a progressive step, and'also to provide an extremely simple and cheaply produced means 56 for accomplishing the functions desired. A
further objection to many prior devices having similar purposes that they involve such increased surface friction that a material Impairment of engine efiiciency results, which it is an object of my invention to overcomes Additional objects advanta s and features of invention areinvolv in the construction, arrangement and combination of parts as indicated in the following descri tionand accompanying drawings, in whie Figure 1 is a perspective viewof a motor vehicle power plant embodying my invention, with. parts broken away for unobstructed observation of essential elements.
Fig. 2 is a longitudinal sectional view of a similar embodiment but upon a different type of motor and vehicle.
Fig. 3 is an elevational view of a motor boat engine having my invention embodied therewit Fig. 4 is a cross section thereof on the line H of Fig. 3.
Fig. 5 is a formal rear view of tin engine, showingthe relation thereto of the element 19 of Fig. 1.
Fig. 6 is a diagrammatioview of a. motor with my invention.
There is illustrated in Figures 1 and 5, a part of a well known type of motor vehicle, including part of the frame 10, the motor 11, a hood 12, which rests upon the familiar dash-board 13 and the radiator 14, while the fan 15 is mounted and belted immediately behind the radiator, and the car buretor 16 is located upon the right hand side of the motor. The motor is provided with the ordinary forms of exhaust and inlet manifolds 17 and 18, the carburetor being mounted upon the lower end of the latter as customary.
The purpose of the invention is to provide a chamber over the motor, closed at all sides except the bottom, ordinarily, and in when the hood is closed. The plate 19 has a horizontal lower edge on level just beuw that of the exhaust manifold, or even which may be secured thereto in an suitable explained. The carburetor with the lower part of the water jacket of a water-cooled engine, .or the uppermostcylinder flanges of an. air cooled engine. In the case of the particular car illustrated in Figs. 1 and 5, there is also provided a small closure plate 20, of a formto close the arched o ening 21 under the dash 13, and around t e motor to a level with the "lower edge of the front plate 19. The hood is preferably formed withno openings above the levelmentioned between the plates 19 and 20, but is formed with'openings 21 of a suitable form before the plate-19in the upper art of the hood. .By this method, when the 00d is closed, it serves as'partof a .chamber 22 of the character desired, into .which will ascend the air heated by the 'motor, or moving thereinto by displacement of air admitted to the carburetor as will 'be 16 in. this instance is of a type which has but one intakepassage, and t 1s 1s fitted with a conduit extension 23 manner, the conduit ha ing a itical'part which extends well up into the space heneath the hood, stopping short of the top thereof a short distance.
In Figure 2 there is indicated a familiar.
make of air-cooled motor 25, the hood 26 of which is customarily provided'with an air inlet, opening .27 at its forward part. In the present instance, I haveprovided upon the motor atits forward end a trans- Y verse partition adapted to fit-within the hood when lowered so as to close communication between the opening 27 and the space to the rear over the engine; The air jacket deck ordinarily provided may; be dispensed with, or otherwise located and the air circulation through the jackets changed.
In Figures 3 and 4' there is illustrated formally a motorv hoatengine 30 provided with a carburetor 31 having two intakes 32 and 33 respectively from each of. which" there are extended upwardly flues 34 and 00' ping at thesame level thereabove, abouhat 35 respectively, of proper form, both stopthe height of to top of the motor Over and around the motor there is a case 36, of ,sln et metal, which maybe hingedly supformed, a. motor mounted atfthe b ported at one -end, and set upon a suitable racket 37 on the crank case of the engine. The case may also be provided with m- -wardiy extending bottom plates 38 along -the forward partby leavingsufiicient openings to admit air in suflicient quantities for the purposes contemplated.
is especially useful in boats where" cross winds and roll ofthe boat may combine to make the construction desirable.
It is-an advantage of the use of my inven: tion that it secures a highly efficient vaporization of fuel superior to the results attained' where the mixture is formed first and heated. afterward; and has been found by tests to efiect' a saving of one half or more ofthe gasoline required" to operate a vehicle having the ordinary carburetor and no heatingappliance for the air of the charge. L Further, it is thought that it will minimize the access of fuel to the lubricating oil, by passing around the pistons, which is supposed to occur in some instances.
, en equipped. with my invention, the motor hasbeen found to run smoothly at all speeds without heating excessively, and
with a'notable absence ofcarbon deposits on the surfaces of the cylinder andpiston.
The device prevents the character of the charge from. being affected by Wir is, which often disturb the operation of motor cars with ordinary equipment; Thus, an engine will 0 crate well at times .when'running with the wind, but not so well'if headedagainst it; Cold cross winds have been known to prevent operation'of a'car, especially when blowing against the side ofthe-car on which the carburetor isl' locatedi. It also has the advantage that t prevents the carburetor action .from being affected materially by ordinary ui, ment.
