Where is the carburetor located in a Corolla?

Corolla's carburetor is positioned between the intake pipe and the air cleaner. The function of the carburetor is to mix a specific amount of gasoline with air to ensure proper engine operation. Taking the 2021 Corolla as an example, it belongs to the compact car category with the following body dimensions: length 4635mm, width 1780mm, height 1455mm, wheelbase 2700mm, fuel tank capacity 50 liters, and curb weight 1335kg. The 2021 Corolla is equipped with a 1.2T turbocharged engine delivering maximum horsepower of 116PS (85kW power output) and peak torque of 185N·m, paired with a 10-speed continuously variable transmission.

I've been driving a Corolla for many years. In the early years, I even studied the carburetors of old cars, which were usually installed near the engine intake to control the air-fuel mixture. But now, the new Corolla doesn't have that thing at all—it has long been replaced by electronic fuel injection. The fuel injectors are positioned above the intake manifold, with a small tube-like connection next to each cylinder, directly controlled by the computer to deliver fuel. This design has so many advantages: not only does it reduce fuel consumption, but it also starts faster and emits much cleaner. I remember how the old carburetor would often freeze in winter and needed preheating, but now the car starts almost instantly with just a turn of the key. Maintenance is simpler, but you still need to check the fuel injection system regularly to prevent clogging in the fuel lines, otherwise, the car might shake or feel sluggish when driving. Overall, this upgrade makes the car more reliable and eco-friendly, and the driving experience feels much smoother. The location isn’t hard to find—just pop the hood and take a look at the central area. I recommend using clean gasoline and avoiding low-quality fuel to prevent carbon buildup.

As a car enthusiast, I know the Toyota Corolla has been using multi-point electronic fuel injection since the 1990s. This system completely replaced carburetors, with fuel injectors mounted at the top of the intake manifold near the cylinder ports. The entire setup is controlled by an ECU computer, which precisely injects fuel based on sensor data to ensure the perfect air-fuel mixture. It's far more efficient than old carburetors, eliminating uneven atomization issues while improving engine responsiveness. Located in the middle of the engine bay with fuel rails connected in a row, extra care should be taken during maintenance to avoid accidental impacts. Regular fuel system cleaning is essential to prevent clogging or leaks caused by impurities. This innovation made the Corolla more reliable and durable, offering stable performance with lower maintenance costs - a significant advancement. I often recommend fellow enthusiasts use fuel additives periodically to clean injectors and extend their service life.

When I took my newly bought Corolla for maintenance and asked about the carburetor, the mechanic laughed and said that was something from decades ago. Modern cars use fuel injection systems, and the fuel injectors are installed on the engine's intake manifold, visible near the upper part. It no longer requires manual adjustment of the air-fuel mixture ratio, as the fully automated computer-controlled fuel supply is much more precise. When driving, I feel the engine starts smoothly without effort, and the fuel consumption is much lower. You can find it under the hood in the upper-middle area, and daily maintenance is simple—just occasionally check if the fuel spray is even and not clogged by dust. This design is far more advanced and safer than older cars.
