What are the effects of severe carbon buildup in the intake manifold?
3 Answers
Severe carbon buildup in the intake manifold can lead to poor engine intake, resulting in engine power loss and idle vibration. 1. Effects: At the same time, the air-fuel mixture becomes too rich, causing noticeable power reduction and accompanied by a certain degree of increased fuel consumption. The increased fuel consumption occurs because to achieve the same power as before carbon buildup, it's necessary to increase the throttle opening angle and provide additional fuel supply. 2. Source of carbon buildup: The carbon deposits in the intake manifold mainly come from oil vapor separated by the crankcase oil separator. When severe carbon buildup occurs in the intake manifold, it affects the normal intake airflow of the engine, and in severe cases, may even obstruct normal engine intake. Additionally, if carbon deposits break off with the airflow and enter the engine interior, they may cause damage to the engine.
When my previous car had severe carbon buildup in the intake tract, it drove like it was gasping for air, with a significant drop in power. Overtaking on the highway took forever, and it would shake during acceleration. Originally, a full tank could last 600 kilometers, but now it ran dry before even hitting 500, with the fuel gauge dropping rapidly and money burning fast. After checking, I found out that the carbon buildup was blocking the intake tract, reducing air intake, causing incomplete fuel combustion, and even emitting black smoke from the exhaust, which was highly polluting. Later, I spent a few hundred to clean the intake tract, and it was back to normal. Regular maintenance with a good fuel additive can really avoid this hassle—saving trouble, money, and being more environmentally friendly.
Intake manifold carbon buildup is terrible. My personal experience with saving money on cars: fuel consumption has skyrocketed. Before, a full tank would last a week, now it's gone in three or four days, costing a lot more on fuel. Carbon buildup restricts air intake, requiring more fuel injection and resulting in poor combustion efficiency. The car feels sluggish, idles unevenly, and emits black smoke from the exhaust, affecting annual inspections. Over time, the engine gets damaged, leading to even higher repair costs. DIY won't cut it—you need a professional to clean the carbon buildup. Use high-quality gasoline regularly to prevent it.
