HEAVY-OIL VAPORIZER.
i I: Application filed December 3, 1924. gerial No. 753,689.
This invention'relates to a means for vaporizing a heavy oil for combustion in an internal combus'tionengine b the heat of the exhaust from the same. t com rises a means whereby the heat from the ex aust is applied to heat the oil and the air for its combustion before the former is-sprayed into the latter and thereafter to heat the ex sive mixture of atomized oil and air be ore 10 its delivery to the intake of the engine.
These three requirements, the heating of the oil, the heating of the air for its combustion and the heating of the gaseous mixture of oil and air are effected within a singlecasting or body which is simple in construction, readily adaptable to existing engines and'accessible for cleaning or repair.
The invention is fully described in the following specification, reference being made to the drawings by which it is accompanied,
in which:
Fig. 1 is a longitudinal section of the invention.
Fig. 2, a plan of the'same with the top cover removed.
Fig. 3 illustrates in'longitudinal section a modification of the invention affording greater accessibility for cleaning, and
Fig. 4, across section of the same.
In these drawings 2 represents a relatively elongated rectangular body, to one end of which the exhaust from theengine is delivered at 3, and from the other end of which it finds its exit at 4. The end of this body to which theexhaust is delivered is downwardly extended as at 5 immediately opposite the exhaust entrance 3 to below the general level of the body, and has in the bottom a compartment 6 divided from it to which the fuel oil is delivered at 7 from the float chamber 23 of the carburetter and from which the oil, heated by exposure to the exhaust, is delivered at 8 to the. ocket 9 of the carburetter 10, which is the su ject of a separate application filed on the 26th August 1924 under Serial No. 734,282 and now pending in the oflice. v
Immediately adjacent the end of the body 2 torwhich the exhaust is delivered, a passage 11 is carried vertically through the body, the lower end of which passage is connected to the carburetter 10 and the upper end of which is connected to the intake of the engine.
From the end of the body 2 which is adjacent this passage 11 to the other end near the exit 4, a series of short tubes 12 pass vertically through'the body, the ends of which tubes are expanded in the apertures propass through the walls of the body, are divided into groups 18, 19, 20 and 21, by flanges projecting from the top and bottom walls of the body on which flanges are seated cover plates 16 above and 17 below, leaving heading spaces 13, 14 and 15 successively connecting the. several groups.
Atmospheric air is admitted to the lower end of the first group 18 of these tubes and passes upward through them to the heading space 13, from there downward .through the tubes in the next group 19 to the heading space 14, upward through the next connected grou 20 to the heading space 15 and downwar through the last group 21 and is delivered at 22 to the carburetter 10 before. referred to;
In this carburetter 10 the air, highly heated by its passage through thetubes 12, re-
through these tubes 12 the ends, where they ceives the atomized oil heated in the compartment 6 and in the pocket 9, and the combustible mixture of heated air and oil vapour passes through the pipe 11 where it is further heated by ex osure to the heat of the exhaust before its elivery to the engine intake.
It will be noted that while the oil in the chamber 6 and the gaseous mixture in the pipe 11 are exposed to the high temperature of the exhaust gases as first delivered from the engine at 3, the air, passing through the tubes 12 from the end nearer the exhaust exit 4toward the end to which the-exhaust is first admitted at 3, is gradually heated until in, the group 21'it is just before its delivery to the carburetter at 22 exposed to the hotter exhaust gases. After this hot air is mixed with the vaporized oil which has beenhighly heated in the chamber'6 and pocket 9, the gaseous mixture in passing through the pipe 11 is, immediately before its delivery to the engine intake, further exposed to the high temperature of the exhaust as first delivered to the chamber 2.
In he m d fi ation Shown in Fig. 3, the
exhaust exit 4, in which plates tubes 26 are secured to extend lengthwise between them. Intermediate the tube plates 26 the body is divided by baflle plates 27, 28, 29 through apertures in which the tubes 26 pass. The
' baflies 27 and 29 extend from the bottom of the body 2 to a short distance from the top, and the baffle 28, from the top to a short distance from the bottom; whereby the air for combustion entering at 30 is constrained to pass upward and over the upper edge of the bathe 27 around the lower edge of the baffle 28, and around the upper edge of the baffle 29 passingthe while between the tubes 26 through which the hot exhaust gases are passing, before being delivered to the carburetter at 22.
Inall other respects the heating boitliy ects the same as previously described and e the same purpose, but has this advantage that is somewhat cheaper to constructand the tubes are accessible for the removal of any carbonaceous deposit within them.
Having now particularly described my invention, I hereby declare that what I claim as new and desire, to be protected in by Letters Patent, is: 1
prising an elongated chambered body through which the exhaust from the engine is passed from one end .to and through the opposite end, said chambered body having a sub-chamber adjacent the end'where the exhaust gases enter the chamberedbody,'and a delivery ducttothe engine intake extend? ing transversely across and through said chambered body adjacent the end where the exhaust gases enter said body, means for separately passingair transversely through said chambered body in a zigzag path to absorb-heat from the exhaust gases, and deliver the heated air to said delivery duct, means to deliver fuel oil from said subchamber into said heated air adjacent to said delivery duct, and means to deliver fuel oil to the sub-chamber. I
' 2. A carburetter of the class described, comprising the combination with an elongated chambered body through which the exhaust from the engine is delivered from one end to the other, said chambered body having a sub-chamber partitioned ofl from it adjacent the exhaust admission and a delivery duct to the engine intake across the I by tubes into tubular spaces and interspaces,
means adjacent the exhaust delivery from the chambered body for admitting air to the chambered body on one side of the tubes while the other side of the tubes is exposedto the exhaust, means for baflling the pas-.
sage of the air through the chambered body, means for delivering the heated air to the delivery pipe, means for delivering oil to the sub-chamber, and means for delivering the oil therefrom into the hot air pipe.
3. A carburetter of the class described, comprising the combination with an elongated chamber through which the exhaust from the engine is passed lengthwise, said chambered body having a sub-chamber immediately adjacent the exhaust admission and a delivery duct to the engine intake across the chambered body at the same end, the remainder of the chambered body from the gas delivery to the other end of the chamber being divided by tubes into tubular spaces and interspaces, means adjacent the exhaust exit for admitting air to one side of the tubes while the exhaust passes in contact with the other side, means for bathing the passage of the air through the chamber in contact with the tubes, means for delivering theair heated by such passage to the delivery pi e, means for controlling, by the 1. A carburetter of the class described co1nsuctiono the enginev intake, the amount of heated airfdelivered, means for delivering oil to the sub-chamber, means for delivering the heated oil into the hot air pipe, and means in the delivery aperture for regulating the amount of oil so delivered.
4. A carburetter of the class described,
comprising the combination with an elon-' gated chambered body through which the exhaust from the engine is passed lengthfor delivering oil from the sub-chamber into the hot air duct adjacent its connection to the delivery duct.
In testimony whereof I aflix my signature.
