In this article you will learn about injection systemsfuel. The carburettor is the very first mechanism that allows to combine gasoline with air in the right proportion for the preparation of a fuel-air mixture and its supply to the combustion chambers of the engine. These devices are actively used to this day - on motorcycles, chainsaws, motorcycles and so on. That's only from the automotive industry, they have long been supplanted by injection injection systems, more advanced and perfect. What is a carburettor? The carburettor is a device thatmixes fuel and air, delivers the resulting mixture to the intake manifold of the internal combustion engine. Early carburettors worked, simply allowing air to pass on the surface of the fuel (in the specific case - gasoline).

But most of them later distributed the measured amount of fuel into the air stream. This air passes through the jets. For a carburetor, the condition of these parts is extremely important. The carburetor was the main instrument for mixingfuel and air in internal combustion engines until the 1980s, when there were doubts about the effectiveness of its use. When burning fuel, a lot of harmful emissions are formed. Although carburettors were used in the United States, Europe and other developed countries until the mid-1990s, they worked alongside more sophisticated control systems to meet the requirements for carbon dioxide emissions. History of development Different types of carburetors have been developeda number of pioneers in the automotive industry, including German engineer Carl Benz, Austrian inventor Siegfried Markus, English scholar Frederick W.

Lanchester and others. Since so many different methods of mixing air and fuel were applied in the early years of the existence and development of cars (and initially stationary petrol engines also used carburetors), it is difficult to determine exactly who is the inventor of this complex device. Types of carburettors Early designs differed inthe main method of work.

They also differ from the more modern ones that dominated throughout much of the twentieth century. Modern carburetor for chainsaw spray type, the same are used on modern cars. The very first, historical, so to speak, designs can be divided into two main types: • Surface type carburetors. • Spray carburetors. Let us examine them in detail later.

Surface carburettors All early carburetor designs weresurface, although there was a great variety in this category. For example, Siegfried Marcus introduced something called the 'rotating carburetor brush' in 1888. And Frederick Lanchester developed his carburettor wick in 1897. The first carburetor float was developed in1885 by William Maybach and Gottlieb Daimler. Karl Benz also patented a carburetor of a float type at about the same time. Nevertheless, these early designs were surface carburetors that worked by passing air over the surface of the fuel in order to mix them. But why do you need a carburetor engine?

And without it, there was no way to feed the fuel mixture to the combustion chambers (the injector was not yet known in the nineteenth century). Most surface devicesfunctioned on the basis of simple evaporation. But there were other carburetors, they were known as devices that work by 'bubbling' (they are also called filter carburetors). They work by forcing the air to move up through the bottom of the fuel chamber.

As a result, a mixture of air and fuel is formed above the main volume of gasoline. And this mixture is subsequently sucked into the intake manifold. Spray carburettors Although various surface carburetors weredominant during the first decades of the car, spray carburetors began to occupy a significant niche at the turn of the 19-20th centuries. Instead of relying on evaporation, these carburetors actually sprayed a measured amount of fuel into the air that was sucked in by the air intake. These carburetors use a float (like Maybach and earlier Benz designs). But they acted on the basis of the Bernoulli principle, as well as the Venturi effect, as well as modern devices, such as the K-68 carburetor. Download tafsir al azhar juz 29. One of the subtypes of aerosol carburettorsis the so-called carburetor pressure.

It first appeared in the 1940s. Although the pressure carburetors resemble aerosols only externally, they were in fact the earliest examples of devices for forced fuel injection (injectors). Instead of relying on the Venturi effect to suck fuel from the chamber, the pressure carburettors sprayed fuel from the valves in much the same way as modern injectors. Carburettors became increasingly complex during the 1980s and 1990s.
