PROVISIONAL SPECIFICATION.
Improvements in or relating to the Vapourization of Hydrocarbons
for Use in Internal Combustion Engines.
1, WILLIAM BAINES, of 5 and 6, Great Winchester Street, in the City of
London, Financial Agent, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the vapourizers of internal combustion engines
and in carrying it into effect 1 combine them with the exhaust of the engine,
preferably in the form of a silencer. This may be effected by employing any
suitable vessel say a cylindrical one into which the exhaust from the engine is
delivered and placing therein a coil of piping or other equivalent device in
which is the hydrocarbon to be vapourized whether mixed with the air or not.
Preferably I mix the hydrocarbon which may be in the form of a heavy or
light oil as preferred with the air either during its passage through the exhaust
or previously so as to obtain the best effect.
By this invention the heat of the exhaust is utilised for vapourizing the
hydrocarbon and mixing it with the air in a manner peculiarly suitable for the
heavier mineral oils, while the temperature of the exhaust is reduced, causing
less noise and smell.

COMPLETE SPECIFICATION.
Improvements in or relating to the Vapourization of Hydrocarbons
for Use in Internal Combustion Engines.
I, WILLIAM BAINES, of 5 and 6, Great Winchester Street, in the City of
this invention
London, Financial Agent, do hereby declare the nature of
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention relates to the vapourizers of internal combustion engines
and in carrying it into effect I combine them with the exhaust of the engine,
preferably in the form of a silencer. This may be effected by employing any
suitable vessel say a cylindrical one into which the exhaust from the engine is
delivered and placing therein a coil of piping or other equivalent device in
which is the hydrocarbon to be vapourized whether mixed with the air or not.
Preferably I mix the hydrocarbon which may be in the form of a heavy.or
light oil as preferred with the air either during its passage through the exhaust
or previously so as to obtain the best effect."
By this invention the heat of the exhaust is utilised for vapourizing the
hydrocarbon and mixing it with the air in a manner peculiarly suitable for the
heavier mineral oils, while the temperature of the exhaust is reduced, causing
less noise and smell.
Three forms of vapourizer constructed according to this invention are shown
in the accompanying drawings, of which

page_text: figure is a pran view of part of the frame work of an auto-car with its
motor showing one form of vapourizer, and
Figure 2 shows an alternative form detached.
Figure 3 is a plan, and
Figure 4 a side view, both partly in section, of a further form of construc-
tion.
Like letters indicate like parts in all figures.
A is the cylinder of an internal combustion engine provided with an inlet
or supply valve B and exhaust valve C. Un to the exhaust valve C is connected
a silencer D, preferably cylindrical as shown, within which is placed a tubular
body E, which forms the vapourizer and heater for the explosive charge; pre-
ferably this is in the form of a helical coil as shown in Figure 1 and is connected
at one end by a--pipe E with the inlet valve B; its other end is connected
through the pipe in any convenient manner with the supply of hydrocarbon
and air,
An alternative form of heater is shown in Figure 2, in which, the tubular
body E is formed of two or more straight pipes connected by a U-bend. The
pipe from the fuel supply may be brought in through the side of the silencer
or the end as most convenient:

Another form of vapourizer is shown in Figures 3 & 4, Fig. 4, being a side
elevation part in section on the line 4-4 of Figure 3. A chamber F is cast or
otherwise formed on one side of the exhaust silencer D, so placed that the
exhaust gases entering the silencer at D1 impinge on the dividing wall F
between the chamber and the silencer. The chamber F is divided by a hori-
zontal septum into two compartments F2 13 communicating at F. The
oil and air are admitted into the upper chamber F through the inlet tube F",
pass into the lower chamber F3 and being heated and vapourized in these
chambers by the exhaust gases, pass as an explosive mixture into the explosion
chamber of the motor through the outlet F, which is connected in any suit-
able manner to the inlet valve C of the motor.
Desirably the exhaust gases pass from the silencer into the atmosphere
through an asbestos cloth as shown at D².
It is evident that the chamber F may if desired be divided into more than
two compartments by additional septa such as 14 so as to give greater length
of travel to the mixture of oil and air.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In an internal combustion engine a vapourizer and heater for the explo-
sive mixture comprising a tubular member such as E. through which the
mixture passes within a casing such as D through which the products of com-
bustion pass substantially as described and illustrated in Figure 1 or Figure 2
of the accompanying drawings.
2. In an internal combustion engine a vapourizer and heater for the explo-
sive mixture comprising a chamber such as F within a casing such as D con-
structed and arranged substantially as described and illustrated in Figures 3
and 4 of the accompanying drawings.
