What happens when fuel injector atomization is poor?

Poor fuel injector atomization can lead to the following situations: 1. Engine shaking; 2. Reduced power and increased fuel consumption; 3. Increased exhaust emissions pollution; 4. Difficulty starting or even stalling; 5. Engine misfire; 6. Black smoke from the exhaust. A fuel injector is an electromagnetic valve that controls the formation of fuel spray entering the engine by opening and closing, which helps the fuel burn more completely. The cleaning method for fuel injectors is: 1. Hang the cleaning device on the front hood of the car; 2. Locate the engine's fuel supply and return lines; 3. Disconnect the return line from the engine and use a suitable plug to block the return line; 4. Connect the fuel supply line to the cleaning device's outlet line; 5. Open the fuel tank cap and remove the fuel pump fuse to stop the fuel pump from working, thus completing the process.
I've been driving that small car for several years, and recently found that poor fuel injector atomization is really troublesome. The engine sounds strange, and when stepping on the gas, the car feels weak, struggling even on slopes. Fuel consumption has been rising sharply - a full tank used to last 500 km, but now it barely makes 400 km, hitting my wallet hard. It's worse at idle - the whole car shakes, and it's prone to stalling when starting, making red lights extremely awkward. Long-term issues like this cause severe engine carbon buildup, with black smoke from the exhaust, frequently getting flagged at inspections. Even more annoying are occasional cold start difficulties, making morning departures stressful. If the injectors are clogged or worn out, they need immediate replacement to avoid ruining the entire car. Finding a reliable repair shop would save a lot of hassle.
Having issues with fuel injector atomization is no small matter in my driving experience. It causes uneven fuel spray, directly leading to incomplete combustion. This results in a lack of engine power, sluggish acceleration, and a significant increase in fuel consumption, costing you more money. The idle becomes unstable, with the car shaking like it's drunk, and in severe cases, it may even fail to start. It also affects emissions, with the exhaust pipe emitting thick black smoke or unpleasant odors, making it easy to fail environmental tests. Over time, severe carbon buildup occurs in the engine, accelerating component wear and doubling repair costs. I recommend checking the fuel system first, cleaning the injectors or trying additives. If they're truly damaged, replacing them is the only option—don't wait until the problem worsens. In short, address this issue early to avoid regret.
