Abstract
A combined air and fuel supply system for an internal combustion engine comprises a fuel tank 1 with a filling pipe 2, a vapour reservoir 3 and an intake manifold 6. A first conduit connects the tank 1 to the reservoir 3 and a second conduit connects the reservoir 3 to the manifold 6. Petrol is stored in the fuel tank 1. The filling pipe 2 extends into the tank 1 so that the pipe's outlet is only 5 mm from the floor of the tank 1. In operation air is drawn through the filling pipe 2, through the fuel causing some of the fuel to vaporise. The air and vapour then pass to the reservoir 3 and from there to the intake manifold 6. A butterfly valve 5 is placed in the manifold 6 to control the flow rate. Two fire traps 4 are installed in the conduit between the reservoir 3 and the manifold 6. The system requires no carburettor, fuel pump or air filter.
Description
1 1 -I- Vapour Engine FuelTank Tank Filler and Air Suction Intake Fuel
Vapour Reserviour Fuel Trap Throttle butterfly Engine Inlet Manifold 2337791 L The Vapour Engine:
An experiment was carried out to prove that any petrol engine, irrespective where it is fitted, can be started and run normally on petrol vapour (fumes).
0 The petrol engine can be run,with some modifications, on any automobile and/or seacraft.
a Accompanied with this report is a drawing explaining the simplicity of, and/or fitting of the alteration to have any petrol engine running from (petrol) vapours.
------------------ 0 The Modification Required:
The petrol filling pipe(2) on the tank end has to be extended and/or'altered in such a way that it is not only used for filling but also as an air suction intake (2).
The filling pipe/tube (2) has to be extended to reach the bottom of the tank with about 5= clearance.
0 An opening on the fuel petrol tank(l) is required to connect the tank to the fuel vapour reservoir(3), about 4cm diameter.
For safety reasons it is recommended that two fire traps(4) are installed between the induction manifold and the vapour reservoir(3),in case of incorrect ignition timing and/or backfiring.
The engine carburettor is to be removed completely, however the throttle butterfly(S) is retained in the same manifold 7neck' for pedal or hand operation (depending the mode of 3 operation) to control engine RPM. An air adjustment screw is required to be fitted to the intake manifold after the butterfly throttle(S) in case of high rich mixture.
A Piping required to connect petrol tank(l) to vapour storage reservoir (3) Piping required to connect vapour storage reservoir(3) to engine inlet manifold(6).
0 0 0 Tank filling pipe(2) to be covered with a breather.
Advantages in this modification and/or running a petrol engine on vapours:
Fuel economy and more miles per gallon.
No carburettor,pumps, and/or filters on the fuel line is necessary, therefore the problems concerning these mentioned items are eliminated.' 3.
No- air cleaner and/or filters are required.
4. No fuel additives ate required.
5.
Less leaded pollution of the atmosphere.
6, Better starting of the engine under any conditions,since also a "choke" is not required. It has to be noted that pure petrol in the combustion chamber chokes. itself and prevents the eng ne from starting. Petrol has to vapourise itself to ignite.
INSTALLATION:
0 The petrol tank(l) has to be flitted in such a way to be connected to the vapour tank(3), in this case PVC piping was used to connect both petrol holding tank(l) and vapour reservoir(3) - as described in drawing.
The petrol tank vapour reservoiffl) has to be connected from another outlet to the engine inlet manifold (6). It is recommended that two fire traps (4) are to be flitted, one nearest to the vapour tank and the other to the engine manifold. In this case PVC piping according to size can be used and secured with hose clips.
The engine carburettor has to be completely removed and as described in the modification, the butterfly throttle (5) to be retained, or refitted, and connected to pedal linkage, or cables, for RPM control. Connect the piping from the vapour tank (3) to the manifold inlet flitting and secure with hose clips.
The fuel vapour reservoir (3) can be mounted directly on top of the fuel tank with two outlets if need be, however one was tested and was satisfactory.
Petrol added in the fuel tank (1) to be as low as possible. No filtration to the fuel is required.
Running:
0 Starting of the engine is normal with the engine giving it a few turns of the self- starter and throttling the engine to the RPM required.
0 The Air drawn from the filling end (2) bubbles up and activates the petrol at low level in the tank, the vapour produced rises and stores itself in the reservoir. The engine is started in a normal way as if it is fitted with a carburettor.
Advantages:
The advantages obtained through this modification are many by not only obtaining more miles to the gallon, but also the fact that no dirt is accumulated and interfering with the engine, since carburation is not necessary any more.
The costly servicing of the carburettor and/or fuel pump is thus eliminated and the smooth running of the petrol engine is obtained through this modification satisfactorily.
