Today’s talk is about direct fuel injection systems, or the so-called GBI Gatlin Direct English, direct injection, meaning gasoline is pumped into the combustion chamber directly, just like diesel engines.
What are fuel systems?
Fuel systems, as we mentioned in the types of fuel systems episode about two years ago, started with sulfur.
Mixing fuel with air?
The primary role is to mix the fuel with the air in a ratio of fourteen point seven and one meaning fourteen point seven molecules is with one molecule of benzene. This ratio is the correct ratio of complete combustion. The scientific development after that to the system of sprays called TBI, or the speed of achievement, so that divination is by means of one or two sprays for the engine as a whole. It is located above the engine prior to studying the air or before the overheating mission initiate, and this is the so-called reason that has come to control this mixing. Computers and sensors. Some engineers said we should try cooking and mixing to the combustion chamber as close as possible to the most accurate, so they created a multi-spray injection system, meaning each cylinder connected to a sprayer that became known as EFI or electronic in which the achievement was achieved.
This gave higher strength and performance than before. Most importantly, fuel exchange is much lower than TBI. Notice that many people and many technicians even think that the sprayer with fuel vapors enters the combustion chamber is Kurdish, while the correct thing is that the fuel must enter the combustion chamber as an anesthetic in the steam and dissolve more particles than the spray, so mixing the fuel is better with it and thus the ignition will be more complete and better and faster. What turns the spray into steam is the air, which is very hot. The spray and comes in contact with very hot, evaporates and enters the combustion chamber.
Has science evolved?
Science has developed, and engineers have told you to try mixing into the combustion chamber like a diesel engine, because if it works like this, there will be higher accuracy in the amount of fuel in economy and in quality. This evaporation will also help reduce the temperature of the combustion chamber, so they made the so-called CIA Army or the ignorant Dark English. Attempts at this system are old. Mercedes started at approximately one thousand nine hundred and fifty-three on aircraft engines and then put it in a rich car, Hendrik Ask, and this was the fastest car of its time, and its speed reached about two hundred and sixty kilometers per hour at that time, but the engine was designed for races more than that of normal use in one thousand nine hundred And ninety-six.
Mitsubishi started with this technology on their cars in general, and around the year 2000 they had more than a million cars on the streets with this technology. After this success, the companies pursued them one unit. The reason behind all this is the strong performance resulting from the lack of fuel consumption, which reached about fifteen percent, in addition to the fact that it has become in strict laws that force manufacturers to reduce harmful emissions to the environment. This system greatly reduced her. I have read a lot on more than one site, Bitclamo, that in the year 2000 or so, the percentage of cars that leave the factories with GPS systems will reach more than eighty percent.
In other words, just as the carbuncle and TBI disappeared, so the traditional cooking system that we know, which is EFI, will disappear and replace the jadei. Even this system works well in turbocharged cars. Even the engines are much smaller than their predecessors. They add turbo with this system. The output is remarkable power, excellent torque, perfect fuel conductance and much less than before. Here is a simple comparison between the two systems. The old EFI system is on the left. And this new system, which is the GPI, is on the right. And here Abdel-Haq has a question that understands me.
If the atomizer turns into steam in EFI, how will it turn into steam in the GPI and atomizer by cooking after country in this kind of engine. The fuel pumps it through the first bronze in the gasoline tank at a pressure of about two to three bar, about thirty or forty in the Si, and this delivers the fuel to a mechanical pump at the end of the engine that raises the pressure to about two hundred bar, meaning about two thousand nine hundred pa, meaning yes to knock two thousand nine hundred pa SIZ Diesel is an extremely high pressure and massive spray that is located inside the combustion chamber either in the head next to the buggy or at the end of the cylinder head designed with very small holes.
The tremendous pressure and small openings will make the fuel come out like steam or hose. When you press the force of the water, you feel a lot, and the design of the orchards has a slight bump. This type works like a ball and helps convert spray into vapor. By the way, there are some companies that still have the two systems, meaning EFI Plus. LPI means if an eight-cylinder car can be thrown with sixteen sprays, six cylinders, twelve steam and four cylinders with eight sprays, and this is a refugee in Lexus cars with a lot of currents, from Ford also in W and many other companies.
Let me show you the express how the two systems work with some of the WiFi, it works at a lower number of revolutions and gives power in this place in the middle. The advantages of this system, such as what we said, is the accuracy in the amount of fuel, and this gives us savings and accuracy in cooking, and this gives us strength, performance and response. Because of this accuracy of emissions and pollution, it will be less and better if we are talking about the disadvantages of this system, so the right of the system is excellent and wonderful. Yes, a little complicated, but the results are excellent and wonderful.
Conclusion
The only thing that most companies avoid talking about is the abnormal carbon deposits on banks specifically, but in the air and also on orchards. These deposits are the engines' dilemma that sometimes makes their performance annoying. Complaints usually come out on difficult chops
