Description

Method for driving an internal combustion engine of the Otto type and internal combustion engine

Any modification to gasoline engines to improve them and thereby reduce gasoline consumption is always welcome be. This is also the subject of this invention, which is a ver driving shows that such a reduction in fuel costs is possible light.

Gasoline engines were improved many years ago and are now extremely powerful and. work excellent, so that they are recognized worldwide and used everywhere.

Due to the day by day rising petrol prices, the engines are losing their economic efficiency in most countries. A solution for this is offered by the diesel engine, which, although its construction is more expensive, uses less fuel needed and more economical. In this invention

procedures are worked out that correctly combine that Allow a gasoline engine to run on diesel fuel.

Even if it seems impossible at first, it is still feasible if one considers the various systems that have been worked out to date.

·> Correctly compiles topics and findings and puts them into practice.

In the carburetor of gasoline engines there is what is known as the venturi system mechanism to vaporize the gasoline in the air and so to form a homogeneous air-gasoline mixture, which in the Zy ^ linder is ignited by the spark from the spark plug. There are also engines that do not have a carburetor and that have a combustion substance is injected directly into the interior of the cylinder. In this case the pressure is between 1 and 7, maximum between 1 and 9.

• When the diesel engine was invented, fuel was preferred in the finest particles into the cylinder. Later developed then injectors and fuel pumps. The pressures of these engines were also 1 to 12 or 1 to 24 to the To increase the temperature with this extreme compression of the air and to avoid a sudden ignition of the fuel works. In summary it can be said that there are two types of engines ^ n there: the petrol and the diesel engines, which one cannot handle. This invention improves the flammability of the

Diesel fuel, so that it can also be used for gasoline engines / u do. However, we consider the following figures:

Compared to gasoline, diesel fuel has the same properties in terms of specific weight, heat output and chemical composition, but differs significantly in terms of viscosity, volatility and flammability, since the physical qualities are different in terms of temperature. If you treat diesel with a temperature of 300 ⁰ C, its properties change and you can turn it into steam. If you then mix it with air, you can ignite it.

If you look closely at the gasoline engine, you will notice that the intake pipe is over the exhaust to collect the heat and thus to vaporize the liquid gasoline particles on the way to the cylinder. But if you accidentally use diesel the liquid particles can take the short way to the cy-

Do not vape linder as they require more time and heat Since diesel fuel can neither be used cold nor at normal temperature, other forms have to be found to completely dry the liquid particles and mix them with air. This is how the mixture can be ignited. This can be achieved as follows:

- A fuel pump (c) (Fig.l) driven by an electric motor or the Camshaft of the engine or can be operated in some other way. The pump picks up diesel fuel (a) from the tank through the suction tube (d) and feeds the fuel back into the tank through line (f), (b)

back (e).

- A control valve (g) through which the diesel fuel increases to the heater Temperature (h) electrical or by burner or by heat the exhaust gases can be heated. So is ge as required Generates enough diesel steam.

- The diesel line (f) leads the steam to the carburetor valve (i), which the

(g) into the heater and vaporizes there (h). Then he gets through the carburetor valve (i), which regulates the amount of steam, continues to the inlet pipe (x) ^ tet, where the steam mixes with the air (k). This mixture can by the effect of the piston (A) in the combustion chamber. The together The compressed mixture can then be ignited by the spark from the spark plug. This procedure works great when the engine is hot but if it is cold the start will be difficult. If you keep the original carburettor of the gasoline engine (Fig. 2), the engine will start instantly. Once again we show how the carburetor works:

The air (k) came through the inlet pipe (x) and absorbs the gasoline in very fine particles, which evaporate in the air and reach the cylinder through the regulating flap (s).
The carburetor valve is open. In this way, the gasoline (p) can get from the tank (o) through (v) to the inlet pipe (x). The carburetor also has a float needle valve (r) to regulate the minimum speed and a float regulator (n) that maintains the fuel level (p) in the tank (o) and, depending on which valve (h) opens or closes, to control the fuel flow through the line (m) to enable. When the engine is cold, it is advisable to close the air flow (k) through the regulating flap (t) in order to obtain a greater vacuum in (v), to enrich the gasoline mixture and to make it easier for the engine to start. In this case the carburetor valve (i) is closed and the engine works normally with petrol.
While the engine warms up in a maximum of 10 minutes (Fig. 3)

^: 1

the pump with the device that will vaporize the diesel fuel should, connected to make the fuel change when the temperature is high enough. The drain valve (j) is opened at short intervals / to remove any liquid diesel residue from the piping system (P). When the line (f) is filled with diesel vapor, the valve

(j) closed again and the fuel change through the carburetor valve (i) and at the same time activated by the closure of the gasoline port valve (q). The regulating flap (s) opens fully to allow air flow (k) to facilitate. This causes the air to mix with the diesel vapor flowing through valve (i) and lead to the cylinder. if If the engine runs on petrol, the regulating flap (s) regulates the acceleration, in the case of diesel fuel it is the carburetor valve (i). The device that starts the fuel change can be operated manually or automatically, depending on the completeness

who you want to build the engine. However, you should definitely read the instructions follow.

If the temperature, the flammability of the Diesel fuel is required cannot be reached, open the carburetor valve (q) (Fig.3) to add some gasoline to the diesel mixture and so the flammability of diesel fuel by 5% or a maximum 10% improvement.

No specific pumps or heaters are named in the invention, either no needle valves, since large quantities of them are on the market, their properties are often very different. The same also applies to the devices available on the market for gasoline-diesel exchange.

The parts should be selected based on your needs when building the engine. The possibilities that this process offers with other fuels are also interesting.

A wide variety of experiments that were carried out with a cold 5 P.S. Motor, a pressure from 1 to 8 and a speed of 3,600 R.P.M. were made. In these experiments, the diesel fuel was burned very cleanly. In order to rule out any errors, they were cleaned the pipes and the tank by removing the valve (q). The engine worked brilliantly and only went out when the valve (i) was opened Diesel evaporation closed.

The method also takes into account the possibility of direct diesel steam into the cylinder (1), which also works very well.

With this procedure there is the possibility to change parts without the To change the principles of fuel combustion. So you can use the carburetor to regulate the air and fuel mixture and thereby very fine liquid diesel particles that are transported through the air to the cylinder are obtained. The only problem is the liquid Particles to evaporate as this is the only way to burn diesel fuel. Since you need a very high temperature for this, you can one heats the inlet pipe electrically or the inlet and exhaust pipe connect to get the necessary warmth.

In Fig.5 you can see that the diameter of the exhaust pipe of an engine (D) is larger, so that there is more heat surface for the evaporation of the diesel fuel to obtain. The inlet pipe (F), which is enclosed by the exhaust pipe (E), conducts the vaporized air-fuel mixture into the

Cylinder.

The heat exchange depends on the ali: of the engine, i. H. in some cases one change will be easy, but in others it will need to be worked out and verified in more detail. With this change, the The size of the carburetor can be precisely calculated for better fuel flow to achieve.

In this way, gasoline engines that were previously built can also use Diesel fuel work. This could be an improvement for future engines mean that diesel fuel has better anti-knock properties than gasoline.

An important aspect of the process is also the simplification of the Today's diesel engines, as the pressure is reduced and the pumps and injection nozzles are also unnecessary.
