Which is more prone to carbon buildup, multi-point fuel injection or direct injection?

[AdalineLee]

Direct injection is more prone to carbon buildup. The injector of direct injection extends into the cylinder, resulting in a harsher working environment compared to multi-point fuel injection, making it highly susceptible to carbon deposits. Below is an introduction to the hazards of carbon buildup: 1. Affects power output: Carbon buildup causes incomplete combustion of gasoline, leading to engine shaking. Engine carbon buildup has a significant impact on vehicles, primarily by reducing engine power, resulting in uneven power output and gradual degradation. 2. Increases fuel consumption: It raises fuel consumption, adding to your financial burden. It also makes cold starts difficult, causing ignition problems and making the vehicle harder to start. 3. Prone to detonation: Carbon buildup in the combustion chamber can cause cylinder knocking, producing noise during low-speed acceleration, damaging pistons and crankshafts, and leading to engine overheating, which severely affects vehicle safety. Additionally, it causes excessive emissions, not only failing annual inspections but also significantly worsening environmental pollution.
