Carburetors were the main fuel delivery system in use on automobiles for a long time. The problem with carburetors is that they are not very efficient at controlling air/fuel ratios, which results in an engine running rough and using more gas. Fuel injection systems like General Motors’ Rochester Quadrajet used today offer significantly better performance than carburetor-equipped engines by providing a constant supply of fuel to the engine’s intake manifold under all operating conditions, including when starting up or coming down from high speeds.
Fuel injection systems also help engines run cooler and more efficiently by ensuring the proper air-to-fuel mixture for different conditions. In a carburetor system, this task is performed by hand as drivers adjust jets to control airflow as they see fit. The process is time-consuming and complicated, however.
In contrast, fuel injection systems automatically monitor intake pressure and deliver precise amounts of gas based on throttle position, engine speed, and several other factors.
here’s the answer why Why Fuel Injection Is Efficient & Better Than a Carburetor:
Carburetors make it almost impossible to precisely control the fuel/air ratio. Because carburetors send a mist of gasoline into the engine’s intake, this ratio varies depending on how much gas is in the float bowl and atmospheric conditions such as temperature and humidity. In other words, carburetors are not only inefficient but they’re also unpredictable.
Fuel injection systems solve these problems because they consist of a sensor that reads airflow from the engine’s intake manifold through a tube connected to the throttle body. The computer then calculates exactly how much gas is needed for optimal power under different conditions and tells an injector at each cylinder to squirt a precise amount of fuel directly into the combustion chamber during specified time periods.
The fuel/air ratio is much better under all conditions. With fuel injection, the optimum ratio for each cylinder occurs at the same point in the engine’s stroke every time. Because carburetors rely on atmospheric conditions, optimal ratios are typically achieved only when an engine is operating between 3,000 and 6,000 RPM.
Because fuel injection systems monitor so many factors simultaneously, they can also improve fuel economy. For example, if one injector malfunctions or clogs during cruise conditions (when airflow into the engine is low), another injector will pick up the slack until the original injector is repaired or replaced. This process can often go unnoticed by owners because it happens seamlessly and instantaneously. Carburetors lack this flexibility because their settings are fixed.
Fuel injection also makes engines run cooler because it uses precise amounts of gas under all conditions, not just when an engine is revved up. Consequently, there is less unburned fuel left over at the end of the power stroke. The reduction in heat allows pistons to stay closer to their ideal operating temperature and prevents them from expanding as much, which can decrease engine wear over time.

Which engine is better carburetor or fuel injection?
As you can see, fuel injection systems are more efficient and offer better performance than carburetors. Carburetor engines don’t have the flexibility of fuel injection ones do, nor do they deliver as reliable a fuel/air ratio. again fuel injection is a lot better than a carburetor and fuel injection is used a lot more
So are carbs are terrible? Not exactly. There are some instances where carburetors actually offer advantages over fuel-injection systems, such as on motorcycles because there is less room for hoses to connect to the intake. Additionally, some drivers simply prefer managing their own gas supply rather than being told what to do by a computer. For many others, however, modern technology has made them obsolete for good reason.
What is the difference between carburetor and fuel injection?
Carburetors atomize gasoline through a suction tube. Fuel injection systems dispense gasoline under high pressure.
Carburetors are less efficient than fuel injection systems. Fuel-injection systems monitor several factors, resulting in more accurate dosing of all cylinders at any given time.
Many modern engine designs have eliminated the carburetor altogether for these reasons. Conversely, carburetor engines are still found on older cars and motorcycles because they’re simple to use and require little maintenance compared to fuel injection ones do. For many drivers, however, the benefits of fuel injection outweigh all other considerations when choosing an engine for their vehicle or motorcycle.

Does fuel injection give more horsepower?
Not necessarily. Carburetors and fuel injection both allow for optimal control of power production depending on the engine’s needs at any given moment, just in different ways.
Both systems offer advantages over the other, with fuel-injection systems offering more flexibility than carburetors do and carburetors offering the same level of optimization over a wider range of possible conditions than fuel injection ones can. For this reason, many new vehicle models use fuel injection while some older ones still use carburetion for simplicity and reliability.
Carburetors and fuel injection systems work much the same way except for one major difference. Carburetors atomize gasoline through a suction tube while fuel injections do so under high pressure.
Fuel injection is more efficient and offers better performance than carburetor engines do, and many modern engine designs have eliminated the carburetor altogether because of these reasons. Conversely, carburetor engines are still found on older cars and motorcycles because they’re simple to use and require little maintenance compared to fuel injection ones do, but that’s changing as new technology becomes available. Because both systems offer advantages over the other depending on how your engine works, it may be useful to understand what kinds of factors affect how your car operates before deciding whether your vehicle should have a carburetor or fuel injection system.
