What are the symptoms of poor fuel injector atomization?
2 Answers
Symptoms of poor fuel injector atomization: 1. Poor engine combustion, shaking, and easy formation of carbon deposits; 2. Due to excessively large diesel droplets not being able to fully combust, they flow along the cylinder wall into the oil pan, increasing the oil level, reducing viscosity, worsening lubrication, and causing accidents such as bearing seizure and cylinder scuffing. The performance of the fuel injector plays a fundamental role in the power output of each engine. To prevent wear on the needle valve and its guide surface, it is necessary to maintain the diesel filter regularly, frequently drain the sediment from the filter and fuel tank to prevent the intrusion of dust and impurities that accelerate the wear of the needle valve assembly. For severely worn needle valves, the needle valve assembly should be replaced promptly with a new one.
My car has been feeling off lately. It's noticeably sluggish when accelerating, and when I press the gas pedal hard to overtake, the engine lacks power, like it's cramping. At idle, the car vibrates significantly, and the steering wheel shakes as if it's about to stall. Fuel consumption has also increased—it used to go 600 km on a full tank, but now it only reaches 550, which is both costly and frustrating. Worse still, it has trouble starting when cold; on winter mornings, it takes several attempts to get it going, and black smoke comes out of the exhaust, polluting the environment. A friend suggested that the fuel injectors might be atomizing poorly, causing large fuel droplets and incomplete combustion, which can lead to carbon buildup in the engine. If not repaired promptly, it could damage the piston rings, significantly increasing repair costs, so I need to get it checked at the garage ASAP. Driving safety is also affected, so it's important to address this issue without delay.
