Automotive engines operating on gasoline do not consume fuel in its pure form, but in the form of a prepared air-fuel mixture with certain proportions of its components. For this process in machines, special devices are used: a carburetor and an injector. These units are mounted on automotive enterprises. However, experts and drivers still have not put an end to the dispute that the carburetor or injector is better.

The distinctive features of the carburetors

An earlier element of the fuel system is the carburetor. It is put on cars since the beginning of the last century. Also, they were equipped with other gasoline engines, installed even on aircraft. A proven way to create a mixture for a long time confirmed its reputation as a reliable and fairly effective component. At the same time it has high maintainability and long trouble-free operation.

The principle of the carburetor is similar to the atomizer, in which the atomized fuel is carried along by the air flow. It enters through the nozzles, and its volume is adjusted using the throttle or crankshaft rotation.

At the end of the 20th century, the injection of carburetor injectors begins to be forced out, and at the beginning of the 21st century, the vast majority of gasoline engines coming off the assembly line almost completely lose their carburetors. The latter remain mainly on sports cars.

Injection systems

Analyzing the features of the difference between the injector and the carburetor, you should know that the formation of a fuel mixture without a carburetor is carried out in the intake manifold or directly in the combustion chamber. The injection and spraying procedure is carried out by special nozzles (injector), thanks to which the system got its name. The most popular are direct injection and distributed.

Work in the system depends on interaction with special sensors that determine several important parameters:

• mass fraction of oxygen in the exhaust gases;
• degree of detonation;
• the position in which the crankshaft is located;
• throttle opening;
• environmental temperature indicators;
• network voltage in the car, etc.

Earlier systems used single injection, in which the mixture was formed in the intake manifold. Modern power plants are equipped with individual nozzles for each cylinder to provide distributed fuel injection.

Modern injectors are considered to be more reliable devices than outdated carburetors when refueling a car with high-quality fuel.

Although some experts when talking about the injector and the carburetor, what is the difference between them point out that in modern systems a larger number of links entails slightly greater risks of failure of individual elements. At the same time, the practice of using more often does not confirm such a rule, especially if one adheres to a rational operation and timely undergoes maintenance.

For moment of sparking watching "electronics" (Electronic control unit), which ensures the long-term operation of the valves without burning through when using high-octane fuel or when the late ignition is set. The composition of the mixture is monitored using a Lambda sensor, and a smaller amount of soot is collected in the cylinders. Sensors responsible for detonation, help to eliminate it, and this saves the pistons and rings from destruction.

You need to know that the difference between the injector and the carburetor is that the latter reacts worse to changing load on the wheels, and accordingly there is more fuel consumption. Because of the simpler design, the carburetors have less opportunity to adapt to external factors, prepare the mixture with a higher degree of error in the proportions, and also have a less flexible instant tuning algorithm.

As a positive factor, the carburetor is more variable for tuning. This is used by car owners, setting up their cars under more comfortable operating conditions.

Injection systems также поддаются перенастройкам, но для этого применяются перепрошивки ЭБУ. Во входных данных специалисты способны сделать больший акцент, например, на динамику.

You need to know that the main reason for the displacement of injectors carburetors have become better indicators of exhaust gases.

Strict environmental standards are maintained using direct injection systems over many thousands of kilometers of run. Rare carburetors are able to strictly adhere to standards higher than those indicated for Euro-1.

What is preferable for the "classic" VAZ

The production of domestic rear-wheel drive cars was carried out with carburetor engines for several decades until 2004, so the bulk of the "classic" VAZ vehicles have this unit under the hood. Only about 7 years, the G7s with injection went off the assembly line.

Carburetor models have shown their high endurance to fuels of various qualities, as well as excellent maintainability. This is especially true of lovers of self-repair cars. Also for these machines there is a low need for high-precision, expensive, specialized equipment. This is an advantage when servicing low-end cars, especially away from major cities. For megacities, this problem is minimized.

Front-wheel domestic cars

For the “nines” family, the injection motor has a fair amount of advantages. There is no need to warm up such a power plant for a long time, and there is also no need to activate the suction at the start. Front-wheel cars were also produced with carburetors, but the main transition to this system was made in 1998. Four-cylinder units with direct injection began to descend from the conveyor.

Based on the opinion of car owners, it can be noted that most of the drivers deliberately chose the type of engine. For those who preferred greater comfort in operation, but agreed with more expensive maintenance, injection engines were more convenient. The car also had lower fuel consumption, higher toxicity, created less problems in the winter.

Car owners, worrying about expensive maintenance, preferred carburetors. Their repair or replacement, even in the service center is very cheap, and sometimes performed independently in the garage.

How to make the right choice

A clear answer to the question about the choice between the carburetor and the injector without the individual characteristics of the car owner will not work. It should be guided only by the fact that the driver wants to get in the end. Fans of self-repair and possible future tuning can safely choose the carburetors. The device is adjusted to individual needs, even in the garage.

When choosing an injector, it is advisable to select newer models that will allow you to enjoy the maximum number of advantages during operation. These include:

• less expense;
• best dynamics;
• environmental friendliness;
• easy start in winter

In any case, in addition to driving features, it is necessary to take into account the possibility of quick and inexpensive repair for all types of engines.
